系统要求

A detailed description of the system requirements for installing and using MERLIC on Windows and Linux systems is provided in the MERLIC manual on the page System Requirements .

Major New Features

主要新功能

New Versioning and Licensing

新版本号与许可协议

With MERLIC 26.03, the transition to the unified MVTec versioning nomenclature in the format Year.Month (YY.MM) takes place. Additionally, customers benefit from a new licensing model. It is simpler and more flexible, as there are now only two packages available: "MERLIC" and "MERLIC Professional."

The "MERLIC" package offers an ideal entry point into the machine vision world. It includes all rule-based features and functions of MERLIC, as well as the two tools “Read Text and Numbers with Deep Learning” and “Count with Deep Learning”.

With MERLIC Professional, users gain access to all remaining deep learning functionalities, as well as all features included in the base package. Additionally, MERLIC Professional allows for the integration of custom MERLIC tools.

For even more customization, MERLIC 26.03 offers two add-ons that can be added to the "MERLIC" package as needed: "MERLIC Deep Learning Add-On" & "MERLIC Custom Tools Add-On". This allows users to select exactly the features they need. The previous limitation on the number of cameras has been removed. Both packages now support an unlimited number of cameras, within technical limits. For users, this means maximum flexibility, easy scalability, and complete future-proofing – regardless of how the application evolves.

"Frontend Observability"

“前端可观测性”

MERLIC 26.03 introduces a new feature that enables complete observability for certain user interactions in the MERLIC Frontend. Users benefit from seamless traceability, knowing who made which changes and when. This ensures secure and transparent operation during ongoing processes and provides all information required to create an audit trail.

MERLIC provides an open interface through which activities like parameter changes or user logins can be automatically transferred to existing observability or audit systems. This not only enhances transparency but also supports compliance and quality requirements in regulated production environments.

Improved "Write Access" Widget

改进的“写入权限”小工具

MERLIC 26.03 makes working with write permissions in the Frontend easier and more secure. The write access widget now clearly indicates whether changes are permitted and whether unsaved changes are pending. This ensures users always maintain full visibility.

Additionally, two new approval actions are available: automatic saving or a save dialog to confirm or discard changes. In combination with user management, different roles can be configured with appropriate approval options – ideal for professional and regulated production environments.

The result: greater usability, enhanced transparency, and controlled, traceable change management during ongoing operations.

New Concept Tool "Tile Images"

新功能“平铺图片”

MERLIC 26.03 introduces the new concept tool “Tile Images.” It allows users to tile two images with the same number of channels into a single composite image – either horizontally or vertically. By applying the tool multiple times, larger image compositions can be created step by step. This helps structure image data clearly and supports efficient downstream processing.

In combination with acquisition sequences, images acquired from line scan or area cameras can be combined into a continuous overall image.

As a concept tool, “Tile Images” is still in an early stage of development. Users are invited to test the functionality and contribute feedback to help shape future MERLIC versions.

Improvements for Deep OCR

深度OCR的改进

The tool "Read Text and Numbers with Deep Learning" now provides a compact, high-performance, and memory-efficient deep learning model. In addition, models optimized for one of MVTec’s AI² interfaces can be used. Advanced parameters provide users with more control over recognition and reading behavior.

Improved print quality verification for 2D Code Quality

改进的二维条码质量打印质量验证

The 2D code tools in MERLIC now support the latest international quality standards ISO/IEC 15415:2024 for printed 2D codes and ISO/IEC 29158:2025 for direct part marking (DPM). This enables more precise and standard-compliant quality inspections.

Compatibility

兼容性

Since the last MERLIC version we have been working hard to improve MERLIC in every way. This has, however, resulted in a few incompatibilities. We apologize for the inconvenience.

• Communication Plug-in SDK       通信插件 SDK

• The communication plug-in support library method " MVPlugin::Config::Builder::WithName() "        has been deprecated and will be removed in a future version. Plug-in        authors should switch to the new " WithKey() "        method instead. If the plug-in's configuration should remain compatible        across the switch, users might need to strip non-alphanumeric characters        manually. For example, " WithName("config_parameter") "        would need to become " WithKey("configparameter") "        to still refer to the same configuration parameter. If compatibility        with plug-in versions using the old " WithName() "        is not a concern, non-alphanumeric characters can be used together with        " WithKey() " and will use the parameter key        as-is. More        information.

• MERLIC RTE Setup   MERLIC       RTE 设置

• The MERLIC RTE Setup is only compatible with MERLIC servers        of the same major version. As a result, the MERLIC RTE Setup of MERLIC        26.03 cannot connect to the MERLIC Creator or MERLIC RTE of MERLIC 5.x        versions. Likewise, the MERLIC RTE Setup of MERLIC 5.x versions cannot        connect to a MERLIC Creator or MERLIC RTE of MERLIC 26.03.

• Tools   工具

• Due to various improvements in MERLIC tools and Designer        widgets, the internal file version of MERLIC Vision Apps (MVApps) has        been increased to version 7. When opening example MVApps created with        earlier MERLIC versions, a conversion dialog is displayed. It is        recommended to review the MVApp after conversion, as the changes may        affect its functionality.

• The MERLIC tool "Acquire Image from Camera" is no        longer available in MERLIC. It has been removed from the        "Legacy" category in the Tool Library. For the image        acquisition from camera devices, we recommend using the Image Source        Manager. More        information.

• The MERLIC tools "Read from Socket" and "Write        to Socket" are no longer available in MERLIC. They have been        removed from the "Legacy" category in the Tool Library. For        the communication via sockets, we recommend using the communication        plug-in "TCP Socket", which is available as an additional        communication plug-in for MERLIC in MVTec Software Manager. More        information.

• Due to the parameter changes for the tool "Read QR        Code", exisiting MERLIC Vision Apps (MVApps) using this tool must        be converted to the new MERLIC version. It is further recommended to        check the functionality of the tool after the MVApp conversion and        adjust the configuration if required. More        information.

• Due to the parameter changes for the tool "Read Text and        Numbers with Deep Learning", exisiting MERLIC Vision Apps (MVApps)        using this tool must be converted to the new MERLIC version. It is        further recommended to check the functionality of the tool after the        MVApp conversion and adjust the configuration if required. More        information.

• MERLIC now supports the newest version of the print quality        inspection standards ISO/IEC 15415:2024 and ISO/IEC 29158. Due to this        update, one of the parameter values for the "Print Quality"        parameter in MERLIC tools for reading 2D data codes has changed.        Therefore, it is recommended to check and update MERLIC Vision Apps        (MVApps), which use these tools and the respective verification        standard. More        information.

• MERLIC tools with deep learning functionality no longer        support deep learning models that were optimized for TensorRT on GPUs        with a compute capability lower than 7.5. The error handling of the        affected tools has been updated accordingly.

• Licensing   许可

• Due to the new licensing model of MERLIC, a new license is        required to use MERLIC 26.03. If MERLIC is started without an activated        license, it will run in trial mode.

• Miscellaneous   其他

• Due to the new underlying HALCON version, the behavior of        existing custom tools may have changed since the last MERLIC version.        Therefore, it is recommended to check the functionality of existing        custom tools in this MERLIC version. More        information.

Security-Related Topics

与安全相关的主题

The following issues are relevant in the context of cybersecurity:

• New Features    新功能

• The release notes now contain an additional section for all        issues that are relevant for cybersecurity.

• The MERLIC manual has been extended with a new page        "Auxiliary Information > Cybersecurity", which provides        security information on MERLIC.

• Fixed Problems 已修复的问题

• If the MERLIC Frontend was connected to an MVApp with user        management and a user was already logged in, the authentication state        could persist when loading another MVApp with its own user management,        for example, when preparing a different recipe or connecting to a        different server. In cases where both MVApps define a user with the same        username but different passwords, the MERLIC Frontend may have granted        access to the newly loaded MVApp without requiring re‑authentication.        This problem has been fixed.

• Internal security checks identified the security        vulnerability CVE-2026-27171 (zlib). The vulnerability concerns the        functions crc32_combine64 and crc32_combine_gen64. These functions are        neither called by MERLIC nor by any third-party libraries used by MERLIC.        Exploitation in the context of MERLIC is therefore not possible and the        CVE is not applicable to our product.

• While opening an MVApp with enabled user management in MERLIC        Creator, it was possible to time the connection of a connecting Frontend        such that the user login was bypassed and the unauthenticated Frontend        received views that it should not have been privy to. These views        remained usable until the Frontend was reconnected. This problem has        been fixed. The user's authentication is now continuously validated and        the Frontend session expires when opening a new user management        database. Note that this problem did not affect MERLIC RTE.

Image Source Manager

图像源管理器

• Enhancements   改进

• The “File” image acquisition interface used by the Image        Source Manager (ISM) and the MERLIC tool “Acquire Image from File” has        been updated to revision 24.11.8.

MERLIC RTE

MERLIC运行时

• New Features    新功能

• MERLIC RTE now supports the transmission of observability        data. For this, MERLIC is instrumented to allow observability of the        MERLIC Frontend via the OpenTelemetry framework. Users may track user        interactions that were made in the MERLIC Frontend while MERLIC RTE is        running. To enable the export of the observability data, MERLIC provides        a new MERLIC INI option " OtlpHttpEndpoint " in        category " [OpenTelemetry] ", which allows setting        the endpoint to which the data shall be sent. If this option is enabled,        MERLIC RTE records and sends observability data regarding the following        actions:

• User logins, user logouts, and password changes

• Acquiring and releasing write access the MERLIC Frontend

• Changing parameter values

• Saving and reverting the program

• MERLIC RTE now allows defining a custom name for a MERLIC RTE        instance to facilitate identifying the instance, for example, when using        the new Frontend obserability feature and monitoring recorded data. The        name can be defined via the new command line option " --name "        or via the MERLIC INI file with the new INI option " InstanceName "        in category " [ProcessIntegration] ". If no instance        name is defined when starting MERLIC RTE, a unique name in the form of a        UUID (universally unique identifier) is assigned by default. The        instance name is also written to the MERLIC log file.

• Fixed Problems 已修复的问题

• MERLIC RTE crashed when the MVApp referenced by a recipe        could not be read at the time the recipe was prepared. This problem has        been fixed. Now, preparing the recipe will fail gracefully, causing        MERLIC RTE to remain in the "Initialized" state and emit an        "Error" event.

Plug-ins for MERLIC RTE

MERLIC运行时插件

• Enhancements   改进

• The OPC UA plug-in has been improved and updated to version        2.4.0. The plug-in now redirects the "trace" information from        the stack and application directly into the MERLIC RTE log files        removing the need of a separate log file. The plug-in configuration has        been adjusted accordingly. The following user parameters have been        removed from the "OPC UA Trace" category as they are no longer        needed:

• Disable flushing of the trace file

• Maximum number of trace entries per file

• Maximum number of trace backup files

• Trace file location

• The configuration options for the OPC UA plug-in have been        improved:

• The category "Endpoint Connection" has been         extended by two new parameters: "Address" and         "Port". They can be used to define the IP address (IPv4 or         IPv6) or host machine of the server, and the port for the connection.         In contrast, the "URL" parameter has been removed from the         configuration because it is no longer needed.

• In the category "Server Certificate", the default         value of the parameter "Domain name" has been changed from         " [NodeName] " to " [HostName] ".         However, using the " [NodeName] " for the parameter         is still possible.

• In the category "Endpoint Security Overrides", the         following parameters have been renamed for more clarity:

• "Accept missing CRLs" has been renamed to          "Accept missing certificate revocation lists"

• "Disable ApplicationUri check" has been renamed          to "Disable application uri check"

• "Disable UserToken PolicyId check" has been          renamed to "Disable user token policy id check

• The Unified Automation OPC UA SDK has been updated to version        2.0.1.

Communication Plug-in SDK

通信插件 SDK

• New Features    新功能

• The MERLIC executable        "merlic_communication_plugin_host.exe" provided for the        development of communication plug-ins has been extended with a new        command line option " --override ". It can be used        to override individual configuration parameters, for example, for        debugging purposes. Additionally, the executable will now print the        configuration parameters that will be used by the plug-in.

• In the communication plug-in support library, " MVPlugin::Config::Builder "        has been extended with the method " WithKey() ",        which allows adding configuration parameters with keys. This keys can        contain dashes ( - ) and underscores ( _ ) in        addition to alphanumeric characters. This method supersedes " WithName() ",        which drops all non-alphanumeric characters and has been deprecated.        Note that this change affects the compatibility. Read        more.

MERLIC RTE Setup

MERLIC运行时设置

• Enhancements   改进

• In the "Recipes" tab of the MERLIC RTE Setup, the        display of the recipe and MVApp descriptions have been improved.        Previously, the texts were wrapped character by character which could        make it hard to read the text. Now, the texts are wrapped word by word.

• Fixed Problems 已修复的问题

• When dragging a section in the configuration area of any tab        in the MERLIC RTE Setup to the right and then reducing the window width,        the contents of the respective section were not visible anymore. This        problem has been fixed.

• In case the MVApp referenced by a recipe could not be parsed,        for example, due to lacking file permissions or a compatibility issue,        the section "Recipe interface" on the "Recipes" tab        of the MERLIC RTE Setup potentially showed follow-up errors pertaining        to ostensibly superfluous recipe values. This problem has been fixed.        The validation of the recipe interface is now skipped in this case.

MERLIC Creator

MERLIC创造器

• New Features    新功能

• The “File” menu of MERLIC Creator and MERLIC Frontend now        includes the new entry “Revert to Last Saved”. It can be used to restore        an MVApp or a recipe to its last saved state.

• Improved Usability  提升了易用性

• Saving write-protected MVApps has been improved. Attempting        to save a write protected MVApp would present a pop-up error stating the        issue, but offering no alternative to save the changes. This problem has        been fixed. The pop-up error now prompts the user to save the MVApp in a        different file.

Frontend Designer

前端设计器

• Fixed Problems 已修复的问题

• The context menu of some widgets in the Frontend Designer        erroneously listed tools without any compatible parameters for the        selected widget. Therefore, widgets could only be connected reliably to        tool parameters and results via the widget properties panel. This        problem has been fixed.

• When resizing the "easyTouch Button" widget in the        Frontend Designer, the background and handle of the widget were not        correctly aligned anymore when the height-to-width ratio of the widget        became too large. This problem has been fixed. Both the handle and        background of the widget are now anchored to the top of the widget.

• If the user canceled the dialog for saving an MVApp in MERLIC        Creator, the menu and controls within the Frontend Designer were still        erroneously disabled. The Frontend Designer could not be used before any        MVApp was actually saved. This problem has been fixed. The Frontend        Designer is now correctly enabled regardless of whether the saving        process was finished or cancelled by the user.

MERLIC Frontend

MERLIC 前端

• New Features    新功能

• The write access mode of the MERLIC Frontend and the        respective Designer widget have been improved. Previously, the        "Write Access" widget could also be used when the MERLIC        Frontend was connected to MERLIC Creator although the write access is granted        by default for connections to MERLIC Creator. As this might have led to        confusion on the intended use, the "Write Access" widget is        now disabled by default if the MERLIC Frontend is connected to MERLIC        Creator. It will only be enabled when the MERLIC Frontend is connected        to a MERLIC RTE instance.
         Additionally, the "Write Access" widget has been extended by a        new property "Release Action". It defines the action that will        be triggered when releasing write access in the MERLIC Frontend or when        the MERLIC Frontend is closed while there are still unsaved changes.        MVApp developers may choose between saving the changes automatically or        showing a save dialog. The save dialog allows Frontend users to specify        a reason for the change but also allows discarding the changes or        canceling the saving process.
         The icon for the "Write Access" widget has also been revised        to make it easier to differentiate the widget from the "easyTouch        Button" widget. It now indicates whether write access is currently        granted in the MERLIC Frontend and whether there are any unsaved        changes. The widget properties now also provide more customization        options for the color of the widget.

• The “File” menu of MERLIC Creator and MERLIC Frontend now        includes the new entry “Revert to Last Saved”. It can be used to restore        an MVApp or a recipe to its last saved state.

• Fixed Problems 已修复的问题

• When a Frontend design contained both an "easyTouch        Button" and a "Training" widget, easyTouch could not be        enabled while the training mode was still active. This problem has been        fixed. Now, both widgets can be enabled any time and, if necessary, the        other widget is automatically disabled.

• An intermittent connectivity issue caused the MERLIC Frontend        to briefly lose connection and then reconnect automatically. If write        access in the MERLIC Frontend was currently granted when the connection        was lost, write access was also released. This problem has been fixed.

• When saving a large MVApp after changing a parameter in the        MERLIC Frontend, the connection could time out before the response of        the server for the saving process was sent back to the client. The        MERLIC Frontend then reconnected but without any indication of what        happened. This problem has been fixed. The timeout has been increased.        Additionally, the user is now notified with a dialog when the response        for the saving process exceeds the timeout.

• If the MERLIC Frontend was connected to an MVApp with user        management and a user was already logged in, the authentication state        could persist when loading another MVApp with its own user management,        for example, when preparing a different recipe or connecting to a        different server. In cases where both MVApps define a user with the same        username but different passwords, the MERLIC Frontend may have granted        access to the newly loaded MVApp without requiring re‑authentication.        This problem has been fixed.

• If an MVApp was reloaded in the MERLIC Frontend because of a        user login or unpreparing and preparing a recipe in MERLIC RTE, the        Frontend design of the MVApp sometimes appeared slightly shifted within        the MERLIC Frontend window. This problem has been fixed.

• When releasing write access in the MERLC Frontend while an        "easyTouch Button" widget or a "Training" widget was        engaged, the connected image display continued to be modified by the        widgets, even though it was not possible to interact with them anymore        until write access was acquired again. This problem has been fixed.        Either widget will now disengage when write access is released and the        image display will be restored accordingly.

• If an MVApp was loaded in MERLIC Creator while the user        management was currently enabled in the Frontend Designer, the Frontend        design was not restored properly. As a consequence, a MERLIC Frontend        connected to MERLIC Creator displayed a blank page instead of the        Frontend design of the loaded MVApp. This problem has been fixed.

• If the "Training" widget was used in a MERLIC        Frontend design in combination with an enabled user management, it did        not display any existing training data. It could be therefore not used        for training in the MERLIC Frontend. This problem has been fixed.

• While opening an MVApp with enabled user management in MERLIC        Creator, it was possible to time the connection of a connecting Frontend        such that the user login was bypassed and the unauthenticated Frontend        received views that it should not have been privy to. These views        remained usable until the Frontend was reconnected. This problem has        been fixed. The user's authentication is now continuously validated and        the Frontend session expires when opening a new user management        database. Note that this problem did not affect MERLIC RTE.

Tools

工具

• New Features    新功能

• The MERLIC tool "Read Text and Numbers with Deep        Learning" has been extended and improved in various ways. It now        supports using optimized Deep OCR models. Additionally, it now allows        setting different processing units and precisions for the detection        component and reading component of the Deep OCR model. For this, the        respective tool parameters and tool results have been replaced as        follows:

• "Processing Unit" has been replaced with         "Processing Unit - Reading" and "Processing Unit -         Detection"

• "Precision" has been replaced with "Precision         - Reading" and "Precision - Detection"

• "Used Processing Unit" has been replaced with         "Used Processing Unit - Reading" and "Used Processing         Unit - Detection"

• "Precision Data Type" has been replaced with         "Precision Data Type - Reading" and "Precision Data Type         - Detection"

As part of this change, further parameters that refer to specific components of the Deep OCR model have been renamed to ensure consistent naming:

• "Detection Model File" has been renamed to         "Model File - Detection"

• "Reading Model File" has been renamed to         "Model File - Reading"

• "Image Width for Reading" has been renamed to         "Image Width - Reading"

Note that this change affects the compatibility. Read more.

• MERLIC has been extended with a new concept tool "Tile        Images". It is available in the tool category "Concept Tools        > Preprocssing". The tool allows tiling two images with the same        number of channels into one image. The tool parameter "Mode"        allows users to choose whether the images are tiled horizontally or        vertically. The tool can be used multiple times to subsequently create        an image based on a sequence of tiled images. In combination with        acquisition sequences, the new concept tool can be used to tile images        that were acquired from a line scan or area camera before proceeding        with the actual image processing tasks.
         This concept tool can be used to evaluate the current stage of        development of this tool. MVTec appreciates any feedback on desired        changes or further feature requests. The feedback can be submitted on        the MERLIC feedback website which can be accessed from the MERLIC        Creator either via the feedback icon on the top right or via the        "Help" menu.

• Enhancements   改进

• The MERLIC tool "Acquire Image from Camera", which        had been deprecated since MERLIC 5.0, has been removed. The tool is no        longer available in the "Legacy" category of the Tool Library        in the MERLIC Creator. Note that this change affects the        compatibility. Read        more.

• The MERLIC tools for reading 2D data codes now support the        newest version of the verification standards for print quality        inspection: ISO/IEC 15415:2024 for print quality inspection of        two-dimensional barcodes and the ISO/IEC 29158:2025 for assessing the        symbol quality of direct marked parts (DPM). This update affects the        following tools:

• Read Aztec Code

• Read Data Matrix ECC 200

• Read PDF417

• Read QR Code

When selecting the respective value in the "Print Quality" parameter, the print quality will be inspected based on the newest version of the seleted standard. Due to this update, the parameter value for the ISO/IEC 29158 standard has been renamed from "ISO/IEC TR 29158 (AIM DPM-1-2006)" to "ISO/IEC 29158". This change applies to the tools "Read Aztec Code", "Read Data Matrix ECC 200", and "Read QR Code". Note that this change affects the compatibility. Read more.

• The MERLIC tool "Read Bar Code" has been improved.        The parameter "Element Width Tolerant" is now also supported        for the code types "Code 128" and "GS1‑128".

• Starting with this MERLIC version, the tools "Read from        File", "Write Image to File", and "Write to        File" are set as legacy. The tools have been moved from the tool        category "File Access" to "Legacy > File Access".        They remain available to provide backward compatibility, but they will        no longer be maintained or updated in upcoming MERLIC versions. We        recommend using the communication plug-ins "save-results" and        "save-images" instead.

• The MERLIC tools "Read from Socket" and "Write        to Socket", which had been deprecated since MERLIC 5.0, have been        removed and are no longer available. As a result, the tools are no        longer provided in the "Legacy" category of the Tool Library        in the MERLIC Creator. Note that this change affects the        compatibility. Read        more.

• The tool parameter "Minimum Contrast" of the MERLIC        tool "Read QR Code" has been removed. The parameter was        already deactivated in the previous MERLIC version and is now no longer        available at this tool. As part of this change, also the respective tool        result "Minimum Contrast Out" has been removed. Note that this        change affects the compatibility. Read        more.

• The MERLIC tool "Read Text and Numbers with Deep        Learning" has been extended with a new Deep OCR reading model. The        respective model file        "pretrained_deep_ocr_reading_compact.hdl" can be selected at        the tool parameter "Model File - Reading". The new model is        slightly less precise than the default model, but it uses significantly        less memory and is much faster during inference.

• Fixed Problems 已修复的问题

• The MERLIC tools "Detect Anomalies" and        "Detect Anomalies in the Global Context" did not perform an        inference if the parameters defining the different thresholds were        modified during the execution, for example, by a connected tool or in        MERLIC RTE mode by an MVApp parameter. This problem has been fixed.

• In the MERLIC tools "Read PDF 417" and "Read        Aztec Code", the range of the parameter "Minimum        Contrast" was incorrectly narrowed to [10..100] . This        problem has been fixed. The valid range has been corrected to [1..255] .

• The parameter value of "Minimum Module Size" in the        MERLIC tool "Read Aztec Code" could not be modified using the        arrow buttons. Additionally, the tool reference of the tools "Read        Aztec Code", "Read Data Matrix ECC 200", and "Read        QR Code" did not mention the correct value range for the parameter        "Maximum Module Size". These problems have been fixed.

• MERLIC could crash when the parameter "Deformation        Tolerance" of the MERLIC tool "Read QR Code" was set to        "curved" and certain images of codes with defect error        corrections were used. This problem has been fixed.

• When loading an MVApp containing the MERLIC tool "Read        Text and Numbers with Deep Learning", a misleading error was logged        if the tool used an optimized recognition model and the parameter        "Recognition Alignment" was enabled. This problem has been        fixed.

• The Japanese translation of several tool parameters and tool        results was inaccurate and did not correctly convey their intended        meaning. For example, for results with the suffix “Out”, the suffix was        translated as 外れ or 値外,        which implies deviation or outliers. This problem has been fixed. The        Japanese translations have been revised to ensure consistent and        accurate representation of their meaning, for example by translating        “Out” as 出力 for output values.

• The values for the tool parameter "Precision" in        MERLIC tools with deep learning functionality have been improved.        Previously, the parameter could be set to "high" or        "medium", which related to the data types "float32"        and "float16". However, these values could lead to confusion        as it was not clear, which data type was internally used for the        respective value. Additionally, precisons other than "float32"        or "float16" were displayed as "unknown". Now, the        parameter values have changed to list the actual data types, for        example, "float32", "float16", or        "bfloat16".

Examples

示例

• New Features    新功能

• MERLIC has been extended with three new examples for Frontend        observabilty. The examples use Docker Compose to define multiple        containers, volumes, and networks in a reproducible way. The example        Dockerfiles and scripts are provided in the directory "examplescontainersobservability"        within the MERLIC installation. For each example, a "Readme"        file is provided, which contains information on the prerequisites and        how to run the example.

• Enhancements 改进

• The MVApp example        "evaluate_ecc_200_print_quality.mvapp" has been updated to the        new ISO/IEC 15415:2024 standard. Furthermore, some additional example        images have been added.

• Improved Usability  提升了易用性

• Saving write-protected MVApps has been improved. Attempting        to save a write protected MVApp would present a pop-up error stating the        issue, but offering no alternative to save the changes. This problem has        been fixed. The pop-up error now prompts the user to save the MVApp in a        different file.

• Fixed Problems 已修复的问题

• Some texts of MVApp examples were not correctly displayed in        the MERLIC Frontend because the specified font family was not available        on the system. The texts were sometimes truncated or displayed with the        system font instead of the specified font. This problem has been fixed.        MERLIC now embeds the font families "Open Sans", "Noto        HK", and "Source Code Pro". Additionally, the Frontend        texts of the example MVApps have been adapted to use the font family        "Open Sans" to ensure that the texts are displayed correctly        on each system.

Documentation

文档

• New Features    新功能

• The release notes now contain an additional section for all        issues that are relevant for cybersecurity.

• The MERLIC manual has been extended with a new page        "Auxiliary Information > Cybersecurity", which provides        security information on MERLIC.

• Enhancements   改进

• The system requirements in the MERLIC manual have been        updated to include Windows IoT Enterprise LTSC 2024.

• The documentation of the write access mode has been improved.        It now describes more clearly the intended use of the write access mode,        the differences depending on the server to which the MERLIC Frontend is        connected, and how to enable the write access in MERLIC RTE mode.

• Improved Usability 提升了易用性

• Accessing the MERLIC documentation via the graphical user        interface of the different MERLIC applications has been improved and        standardized to be more intuitive. The "Help" menus of MERLIC        Creator, Frontend Designer, and MERLIC Frontend now provide two        distinctive menu entries to access help: one for accessing the start        menu of the MERLIC manual and one to access the context-help of the        currently focused element. The menus also show the respective keyboard        shortcuts. Additionally, the MERLIC RTE Setup has been extended with a        help button on the top-right corner to access the context-help of the        current tab via mouse-click.

• Fixed Problems 已修复的问题

• The MERLIC manual did not provide any information on which        MQTT version is used by the MQTT plug-in. This problem has been fixed.

• In the MERLIC manual, the page "Installed File        Structure" has been renamed to "Created and Installed File        Structure". Furthermore, a new table has been added to provide a        clearer overview of additional configuration files and log files that        are created while working with MERLIC.

• In the MERLIC manual, some pages referring to resizing the        tool flow of an MVApp did not show the correct icon for the "Reset        zoom to 100%" button. This problem has been fixed.

• In the MERLIC manual, several terms referring to the OPC UA        plug-in and OPC UA server were not used correctly. This resulted in        inaccurate and inconsistent translations on some pages. This problem has        been fixed.

• On the page "Speed-Up Tips" in the MERLIC manual,        the section "Disabling Foreground Window Priority Boost" was        not translated. This problem has been fixed.

• In the MERLIC manual, various screenshots and screencasts of        the MERLIC Frontend were outdated. This problem has been fixed.

• In the MERLIC manual, equations containing text were not        displayed correctly accross all languages. The text font was set to        italic, which is appropriate for the English and German manual but not        for Chinese and Japanese. This problem has been fixed. Text within        equations are still displayed in italic font in the English and German        manuals. In the Chinese and Japanese manuals, however, the characters        are now displayed in regular (non-italic) font to ensure proper        readability and language-specific formatting.
