 # Release Notes for C++ Edition - 3.x
 
+## 3.6.1000 (07/23/2026)
+
+### Highlights
+
+#### Multimodal PDF Content Extraction
+
+- **New PDF Reading Mode** - Added [`PDFRM_MULTIMODAL`]({{ site.dcvb_cpp_api }}core/enum-pdf-reading-mode.html) to [`PDFReadingMode`]({{ site.dcvb_cpp_api }}core/enum-pdf-reading-mode.html), now the default for [`PDFReadingParameter`]({{ site.dcvb_cpp_api }}core/basic-structures/pdf-reading-parameter.html). It extracts vector graphics, text content, and embedded images from PDF files, enabling stronger barcode reading performance in multimodal PDF scenarios.
+- **Performance Behavior Update** - Compared with full-page raster rendering, [`PDFRM_MULTIMODAL`]({{ site.dcvb_cpp_api }}core/enum-pdf-reading-mode.html) usually improves speed by avoiding unnecessary rendering of irrelevant regions.
+
+#### Multi-Threaded Barcode Decoding
+
+- **Get results sooner with parallel processing** - Barcode decoding now uses a breadth-first strategy that decomposes a single DBR Task into one Localization Work and one or more Decoding Works. This improves thread utilization and reduces the chance that a slow `DeblurMode` attempt blocks other faster decoding attempts, helping valid results come back sooner.
+
+#### DataMatrix Color Inversion Detection
+
+- **Handle normal and inverted DataMatrix more efficiently** - Added [`AutoDetectColorInversion`]({{ site.dcvb_parameters_reference }}barcode-format-specification/auto-detect-color-inversion.html) to automatically handle both normal and inverted DataMatrix barcodes. Instead of processing the whole image twice, the SDK applies dual-polarity handling only to localized DataMatrix regions, which makes processing faster in dual-polarity scenarios.
+
+#### Barcode Layout Analysis
+
+- **Decode dense grid barcodes more completely** - Added [`CLayoutAnalyzer`]({{ site.dcvb_cpp_api }}utility/layout-analyzer.html) to organize barcode locations into logical line or matrix layouts and infer unrecognized barcode regions when gaps exist, enabling workflows such as fast first-pass decoding, missing-region inference, and targeted second-pass decoding on dense N*M barcode layouts.
+
+#### Cross-Version License Support
+
+- **Use a single license across SDK versions** - Full License 1.0 keys (starting with "f") that are non-perpetual are no longer version-checked, so the same key can be used across SDK versions without reactivation.
+
+#### Text Line Orientation Detection
+
+- **Support text lines in arbitrary orientations more automatically** - Added [`OrientationDetectionModes`]({{ site.dcvb_parameters_reference }}label-recognizer-task-settings/orientation-detection-modes.html) to automatically detect text line orientation and correct the orientation of text lines for further processing. Two modes are available: `ODM_SPATIAL_REFERENCES` and `ODM_CHARS_ORIENTATION_NEURAL_NETWORK`.
+
+### New
+
+- Added [`PDFRM_MULTIMODAL`]({{ site.dcvb_cpp_api }}core/enum-pdf-reading-mode.html) value to [`PDFReadingMode`]({{ site.dcvb_cpp_api }}core/enum-pdf-reading-mode.html) enumeration for multimodal PDF content extraction.
+
+- Added [`AutoDetectColorInversion`]({{ site.dcvb_parameters_reference }}barcode-format-specification/auto-detect-color-inversion.html) parameter for `BarcodeFormatSpecification` to support automatic color-inversion detection for DataMatrix barcodes.
+
+- Added a new overload of [`CaptureMultiPages()`]({{ site.dcvb_cpp_api }}capture-vision-router/single-file-processing.html#capturemultipages) that accepts a [`CFileFetcher`]({{ site.dcvb_cpp_api }}utility/file-fetcher.html) parameter for more flexible file input handling.
+
+- Added [`CLayoutAnalyzer`]({{ site.dcvb_cpp_api }}utility/layout-analyzer.html) class with [`Analyze()`]({{ site.dcvb_cpp_api }}utility/layout-analyzer.html#analyze) and [`ReleaseResult()`]({{ site.dcvb_cpp_api }}utility/layout-analyzer.html#releaseresult) static methods for quadrilateral layout analysis.
+
+- Added [`LayoutPattern`]({{ site.dcvb_cpp_api }}utility/enum-layout-pattern.html) enumeration with values `LP_UNKNOWN`, `LP_LINES`, and `LP_MATRIX`.
+
+- Added [`LayoutElementSource`]({{ site.dcvb_cpp_api }}utility/enum-layout-element-source.html) enumeration with values `LES_NONE`, `LES_INPUT`, and `LES_INFERRED`.
+
+- Added [`MeasureUnit`]({{ site.dcvb_cpp_api }}core/enum-measure-unit.html) enumeration with values `MU_PIXEL` and `MU_PERCENTAGE`.
+
+- Added structures [`LayoutAxis`]({{ site.dcvb_cpp_api }}utility/layout-axis.html), [`LayoutAnalysisParameter`]({{ site.dcvb_cpp_api }}utility/layout-analysis-parameter.html), [`LayoutElement`]({{ site.dcvb_cpp_api }}utility/layout-element.html), and [`LayoutAnalysisResult`]({{ site.dcvb_cpp_api }}utility/layout-analysis-result.html) for layout analysis configuration and results.
+
+- Added a new `GridBarcodeScanner` sample (with `sample_grid.png`) to demonstrate how to use [`CLayoutAnalyzer`]({{ site.dcvb_cpp_api }}utility/layout-analyzer.html) for barcode grid layout detection and logical row/column mapping.
+
+- Added [`OrientationDetectionModes`]({{ site.dcvb_parameters_reference }}label-recognizer-task-settings/orientation-detection-modes.html) parameter for the [`SST_LOCALIZE_TEXT_LINES`]({{ site.dcvb_parameters_reference }}label-recognizer-task-settings/stage-localize-text-lines.html) stage with two supported modes: `ODM_SPATIAL_REFERENCES` and `ODM_CHARS_ORIENTATION_NEURAL_NETWORK`.
+
+- Added `TextLineOrientationCls.data` model file for text line orientation classification.
+
+- Added a new overload of [`FindPortraitZone()`]({{ site.dcvb_cpp_api }}id-utility/identity-processor.html#findportraitzone) that accepts an additional `isBlankPortrait` output parameter, which indicates whether the detected portrait zone is blank.
+
+### Changed
+
+- Default [`PDFReadingMode`]({{ site.dcvb_cpp_api }}core/enum-pdf-reading-mode.html) in [`PDFReadingParameter`]({{ site.dcvb_cpp_api }}core/basic-structures/pdf-reading-parameter.html) constructor changed from [`PDFRM_RASTER`]({{ site.dcvb_cpp_api }}core/enum-pdf-reading-mode.html) to [`PDFRM_MULTIMODAL`]({{ site.dcvb_cpp_api }}core/enum-pdf-reading-mode.html).
+
+- [`MaxParallelTasks`]({{ site.dcvb_parameters_reference }}capture-vision-template/max-parallel-tasks.html) now controls the total number of concurrent Work threads in the CVR thread pool. For DBR tasks, each Localization Work and Decoding Work occupies one thread slot. DLR and DDN tasks continue to occupy one thread per task.
+
+- [`SetDeviceFriendlyName()`]({{ site.dcvb_cpp_api }}license/license-manager.html#setdevicefriendlyname) now enforces parameter constraints: maximum 64 characters, allowed characters are letters (a-z, A-Z), digits (0-9), hyphen (-), underscore (_), and period (.), and must start and end with a letter or digit. Returns [`EC_PARAMETER_VALUE_INVALID`]({{ site.dcvb_cpp_api }}core/enum-error-code.html) if constraints are not met.
+
+- The Linux ARM64 minimum requirement is now glibc 2.27 (Ubuntu 18.04+, Debian 10+, and CentOS/RHEL 8+).
+
+- The Visual Studio minimum requirement is now VS2015.
+
+### Improved
+
+- Updated `MRZLocalization.data` model for improved portrait zone detection accuracy.
+
+- [`FindPortraitZone()`]({{ site.dcvb_cpp_api }}id-utility/identity-processor.html#findportraitzone) now returns the portrait zone quadrilateral with the top-left corner of the upright portrait as the first point.
+
+- Improved `idNumberType` field extraction accuracy for `SOUTH_AFRICA_DL` parsing.
+
+### Fixed
+
+- Fixed a crash that could occur in AWS Lambda environments under certain conditions.
+
+- Fixed an issue in GS1-Databar AI `17` (YYMMDD) results where the month field could be missing a leading zero.
+
+### Deprecations
+
+- Marked `PDFRM_VECTOR` as deprecated (covered by [`PDFRM_MULTIMODAL`]({{ site.dcvb_cpp_api }}core/enum-pdf-reading-mode.html)).
+
 ## 3.4.3000 (06/30/2026)

-
-Specifies the minimum time interval (in milliseconds) allowed between consecutive image captures.
-
-```csharp
-int minImageCaptureInterval;
-```
-
-**Remarks**
-
-This property represents the minimum time interval (in milliseconds) that must elapse before the next image capture operation can be initiated.
-Setting a larger value for this property will introduce a delay between image captures, while setting a smaller value allows for more frequent captures. It can be used to reduce the computational frequency, which can effectively lower energy consumption. Please note that the actual time interval between captures may be longer than the specified minimum interval due to various factors, such as image processing time and hardware limitations.

 # Release Notes for .NET Edition - 3.x
 
+## 3.6.1000 (07/23/2026)
+
+### Highlights
+
+#### Multimodal PDF Content Extraction
+
+- **New PDF Reading Mode** - Added [`PDFRM_MULTIMODAL`]({{ site.dcvb_dotnet_api }}core/enum-pdf-reading-mode.html) to [`PDFReadingMode`]({{ site.dcvb_dotnet_api }}core/enum-pdf-reading-mode.html), now the default for [`PDFReadingParameter`]({{ site.dcvb_dotnet_api }}core/basic-classes/pdf-reading-parameter.html). It extracts vector graphics, text content, and embedded images from PDF files, enabling stronger barcode reading performance in multimodal PDF scenarios.
+- **Performance Behavior Update** - Compared with full-page raster rendering, [`PDFRM_MULTIMODAL`]({{ site.dcvb_dotnet_api }}core/enum-pdf-reading-mode.html) usually improves speed by avoiding unnecessary rendering of irrelevant regions.
+
+#### Multi-Threaded Barcode Decoding
+
+- **Get results sooner with parallel processing** - Barcode decoding now uses a breadth-first strategy that decomposes a single DBR Task into one Localization Work and one or more Decoding Works. This improves thread utilization and reduces the chance that a slow `DeblurMode` attempt blocks other faster decoding attempts, helping valid results come back sooner.
+
+#### DataMatrix Color Inversion Detection
+
+- **Handle normal and inverted DataMatrix more efficiently** - Added [`AutoDetectColorInversion`]({{ site.dcvb_parameters_reference }}barcode-format-specification/auto-detect-color-inversion.html) to automatically handle both normal and inverted DataMatrix barcodes. Instead of processing the whole image twice, the SDK applies dual-polarity handling only to localized DataMatrix regions, which makes processing faster in dual-polarity scenarios.
+
+#### Barcode Layout Analysis
+
+- **Decode dense grid barcodes more completely** - Added [`LayoutAnalyzer`]({{ site.dcvb_dotnet_api }}utility/layout-analyzer.html) to organize barcode locations into logical line or matrix layouts and infer unrecognized barcode regions when gaps exist, enabling workflows such as fast first-pass decoding, missing-region inference, and targeted second-pass decoding on dense N*M barcode layouts.
+
+#### Cross-Version License Support
+
+- **Use a single license across SDK versions** - Full License 1.0 keys (starting with "f") that are non-perpetual are no longer version-checked, so the same key can be used across SDK versions without reactivation.
+
+#### Text Line Orientation Detection
+
+- **Support text lines in arbitrary orientations more automatically** - Added [`OrientationDetectionModes`]({{ site.dcvb_parameters_reference }}label-recognizer-task-settings/orientation-detection-modes.html) to automatically detect text line orientation and correct the orientation of text lines for further processing. Two modes are available: `ODM_SPATIAL_REFERENCES` and `ODM_CHARS_ORIENTATION_NEURAL_NETWORK`.
+
+### New
+
+- Added a DLL build targeting .NET 8.
+
+- Added [`PDFRM_MULTIMODAL`]({{ site.dcvb_dotnet_api }}core/enum-pdf-reading-mode.html) value to [`PDFReadingMode`]({{ site.dcvb_dotnet_api }}core/enum-pdf-reading-mode.html) enumeration for multimodal PDF content extraction.
+
+- Added [`AutoDetectColorInversion`]({{ site.dcvb_parameters_reference }}barcode-format-specification/auto-detect-color-inversion.html) parameter for `BarcodeFormatSpecification` to support automatic color-inversion detection for DataMatrix barcodes.
+
+- Added a new overload of [`CaptureMultiPages()`]({{ site.dcvb_dotnet_api }}capture-vision-router/single-file-processing.html#capturemultipages) that accepts a [`FileFetcher`]({{ site.dcvb_dotnet_api }}utility/file-fetcher.html) parameter for more flexible file input handling.
+
+- Added [`LayoutAnalyzer`]({{ site.dcvb_dotnet_api }}utility/layout-analyzer.html) class with [`Analyze()`]({{ site.dcvb_dotnet_api }}utility/layout-analyzer.html#analyze) static method for quadrilateral layout analysis.
+
+- Added [`LayoutPattern`]({{ site.dcvb_dotnet_api }}utility/enum-layout-pattern.html) enumeration with values `LP_UNKNOWN`, `LP_LINES`, and `LP_MATRIX`.
+
+- Added [`LayoutElementSource`]({{ site.dcvb_dotnet_api }}utility/enum-layout-element-source.html) enumeration with values `LES_NONE`, `LES_INPUT`, and `LES_INFERRED`.
+
+- Added [`MeasureUnit`]({{ site.dcvb_dotnet_api }}core/enum-measure-unit.html) enumeration with values `MU_PIXEL` and `MU_PERCENTAGE`.
+
+- Added structures [`LayoutAxis`]({{ site.dcvb_dotnet_api }}utility/layout-axis.html), [`LayoutAnalysisParameter`]({{ site.dcvb_dotnet_api }}utility/layout-analysis-parameter.html), [`LayoutElement`]({{ site.dcvb_dotnet_api }}utility/layout-element.html), and [`LayoutAnalysisResult`]({{ site.dcvb_dotnet_api }}utility/layout-analysis-result.html) for layout analysis configuration and results.
+
+- Added a new `GridBarcodeScanner` sample (with `sample_grid.png`) to demonstrate how to use [`LayoutAnalyzer`]({{ site.dcvb_dotnet_api }}utility/layout-analyzer.html) for barcode grid layout detection and logical row/column mapping.
+
+- Added [`OrientationDetectionModes`]({{ site.dcvb_parameters_reference }}label-recognizer-task-settings/orientation-detection-modes.html) parameter for the [`SST_LOCALIZE_TEXT_LINES`]({{ site.dcvb_parameters_reference }}label-recognizer-task-settings/stage-localize-text-lines.html) stage with two supported modes: `ODM_SPATIAL_REFERENCES` and `ODM_CHARS_ORIENTATION_NEURAL_NETWORK`.
+
+- Added `TextLineOrientationCls.data` model file for text line orientation classification.
+
+### Changed
+
+- Default [`PDFReadingMode`]({{ site.dcvb_dotnet_api }}core/enum-pdf-reading-mode.html) in [`PDFReadingParameter`]({{ site.dcvb_dotnet_api }}core/basic-classes/pdf-reading-parameter.html) constructor changed from [`PDFRM_RASTER`]({{ site.dcvb_dotnet_api }}core/enum-pdf-reading-mode.html) to [`PDFRM_MULTIMODAL`]({{ site.dcvb_dotnet_api }}core/enum-pdf-reading-mode.html).
+
+- [`MaxParallelTasks`]({{ site.dcvb_parameters_reference }}capture-vision-template/max-parallel-tasks.html) now controls the total number of concurrent Work threads in the CVR thread pool. For DBR tasks, each Localization Work and Decoding Work occupies one thread slot. DLR and DDN tasks continue to occupy one thread per task.
+
+- [`SetDeviceFriendlyName()`]({{ site.dcvb_dotnet_api }}license/license-manager.html#setdevicefriendlyname) now enforces parameter constraints: maximum 64 characters, allowed characters are letters (a-z, A-Z), digits (0-9), hyphen (-), underscore (_), and period (.), and must start and end with a letter or digit. Returns [`EC_PARAMETER_VALUE_INVALID`]({{ site.dcvb_dotnet_api }}core/enum-error-code.html) if constraints are not met.
+
+- Removed the VC++ Redistributable runtime dependency for the native C DLL on Windows (runtime linkage changed from MD to MT).
+
+### Improved
+
+- Updated `MRZLocalization.data` model for improved portrait zone detection accuracy.
+
+- [`FindPortraitZone()`]({{ site.dcvb_dotnet_api }}id-utility/identity-processor.html#findportraitzone) now returns the portrait zone quadrilateral with the top-left corner of the upright portrait as the first point.
+
+- Improved `idNumberType` field extraction accuracy for `SOUTH_AFRICA_DL` parsing.
+
+### Fixed
+
+- Fixed a crash that could occur in AWS Lambda environments under certain conditions.
+
+- Fixed an issue in GS1-Databar AI `17` (YYMMDD) results where the month field could be missing a leading zero.
+
+### Deprecations
+
+- Marked `PDFRM_VECTOR` as deprecated (covered by [`PDFRM_MULTIMODAL`]({{ site.dcvb_dotnet_api }}core/enum-pdf-reading-mode.html)).
+
 ## 3.4.3000 (06/30/2026)

 # Release Notes for Java Edition - 3.x
 
+## 3.6.1000 (07/23/2026)
+
+### Highlights
+
+#### Multimodal PDF Content Extraction
+
+- **New PDF Reading Mode** - Added [`PDFRM_MULTIMODAL`]({{ site.dcvb_java_api }}core/enum-pdf-reading-mode.html) to [`PDFReadingMode`]({{ site.dcvb_java_api }}core/enum-pdf-reading-mode.html), now the default for [`PDFReadingParameter`]({{ site.dcvb_java_api }}core/basic-classes/pdf-reading-parameter.html). It extracts vector graphics, text content, and embedded images from PDF files, enabling stronger barcode reading performance in multimodal PDF scenarios.
+- **Performance Behavior Update** - Compared with full-page raster rendering, [`PDFRM_MULTIMODAL`]({{ site.dcvb_java_api }}core/enum-pdf-reading-mode.html) usually improves speed by avoiding unnecessary rendering of irrelevant regions.
+
+#### Multi-Threaded Barcode Decoding
+
+- **Get results sooner with parallel processing** - Barcode decoding now uses a breadth-first strategy that decomposes a single DBR Task into one Localization Work and one or more Decoding Works. This improves thread utilization and reduces the chance that a slow `DeblurMode` attempt blocks other faster decoding attempts, helping valid results come back sooner.
+
+#### DataMatrix Color Inversion Detection
+
+- **Handle normal and inverted DataMatrix more efficiently** - Added [`AutoDetectColorInversion`]({{ site.dcvb_parameters_reference }}barcode-format-specification/auto-detect-color-inversion.html) to automatically handle both normal and inverted DataMatrix barcodes. Instead of processing the whole image twice, the SDK applies dual-polarity handling only to localized DataMatrix regions, which makes processing faster in dual-polarity scenarios.
+
+#### Barcode Layout Analysis
+
+- **Decode dense grid barcodes more completely** - Added [`LayoutAnalyzer`]({{ site.dcvb_java_api }}utility/layout-analyzer.html) to organize barcode locations into logical line or matrix layouts and infer unrecognized barcode regions when gaps exist, enabling workflows such as fast first-pass decoding, missing-region inference, and targeted second-pass decoding on dense N*M barcode layouts.
+
+#### Cross-Version License Support
+
+- **Use a single license across SDK versions** - Full License 1.0 keys (starting with "f") that are non-perpetual are no longer version-checked, so the same key can be used across SDK versions without reactivation.
+
+#### Text Line Orientation Detection
+
+- **Support text lines in arbitrary orientations more automatically** - Added [`OrientationDetectionModes`]({{ site.dcvb_parameters_reference }}label-recognizer-task-settings/orientation-detection-modes.html) to automatically detect text line orientation and correct the orientation of text lines for further processing. Two modes are available: `ODM_SPATIAL_REFERENCES` and `ODM_CHARS_ORIENTATION_NEURAL_NETWORK`.
+
+### New
+
+- Added [`PDFRM_MULTIMODAL`]({{ site.dcvb_java_api }}core/enum-pdf-reading-mode.html) value to [`PDFReadingMode`]({{ site.dcvb_java_api }}core/enum-pdf-reading-mode.html) enumeration for multimodal PDF content extraction.
+
+- Added [`AutoDetectColorInversion`]({{ site.dcvb_parameters_reference }}barcode-format-specification/auto-detect-color-inversion.html) parameter for `BarcodeFormatSpecification` to support automatic color-inversion detection for DataMatrix barcodes.
+
+- Added a new overload of [`captureMultiPages()`]({{ site.dcvb_java_api }}capture-vision-router/single-file-processing.html#capturemultipages) that accepts a [`FileFetcher`]({{ site.dcvb_java_api }}utility/file-fetcher.html) parameter for more flexible file input handling.
+
+- Added [`LayoutAnalyzer`]({{ site.dcvb_java_api }}utility/layout-analyzer.html) class with [`analyze()`]({{ site.dcvb_java_api }}utility/layout-analyzer.html#analyze) static method for quadrilateral layout analysis.
+
+- Added [`LayoutPattern`]({{ site.dcvb_java_api }}utility/enum-layout-pattern.html) enumeration with values `LP_UNKNOWN`, `LP_LINES`, and `LP_MATRIX`.
+
+- Added [`LayoutElementSource`]({{ site.dcvb_java_api }}utility/enum-layout-element-source.html) enumeration with values `LES_NONE`, `LES_INPUT`, and `LES_INFERRED`.
+
+- Added [`MeasureUnit`]({{ site.dcvb_java_api }}core/enum-measure-unit.html) enumeration with values `MU_PIXEL` and `MU_PERCENTAGE`.
+
+- Added structures [`LayoutAxis`]({{ site.dcvb_java_api }}utility/layout-axis.html), [`LayoutAnalysisParameter`]({{ site.dcvb_java_api }}utility/layout-analysis-parameter.html), [`LayoutElement`]({{ site.dcvb_java_api }}utility/layout-element.html), and [`LayoutAnalysisResult`]({{ site.dcvb_java_api }}utility/layout-analysis-result.html) for layout analysis configuration and results.
+
+- Added a new `GridBarcodeScanner` sample (with `sample_grid.png`) to demonstrate how to use [`LayoutAnalyzer`]({{ site.dcvb_java_api }}utility/layout-analyzer.html) for barcode grid layout detection and logical row/column mapping.
+
+- Added [`OrientationDetectionModes`]({{ site.dcvb_parameters_reference }}label-recognizer-task-settings/orientation-detection-modes.html) parameter for the [`SST_LOCALIZE_TEXT_LINES`]({{ site.dcvb_parameters_reference }}label-recognizer-task-settings/stage-localize-text-lines.html) stage with two supported modes: `ODM_SPATIAL_REFERENCES` and `ODM_CHARS_ORIENTATION_NEURAL_NETWORK`.
+
+- Added `TextLineOrientationCls.data` model file for text line orientation classification.
+
+### Changed
+
+- Default [`PDFReadingMode`]({{ site.dcvb_java_api }}core/enum-pdf-reading-mode.html) in [`PDFReadingParameter`]({{ site.dcvb_java_api }}core/basic-classes/pdf-reading-parameter.html) constructor changed from [`PDFRM_RASTER`]({{ site.dcvb_java_api }}core/enum-pdf-reading-mode.html) to [`PDFRM_MULTIMODAL`]({{ site.dcvb_java_api }}core/enum-pdf-reading-mode.html).
+
+- [`MaxParallelTasks`]({{ site.dcvb_parameters_reference }}capture-vision-template/max-parallel-tasks.html) now controls the total number of concurrent Work threads in the CVR thread pool. For DBR tasks, each Localization Work and Decoding Work occupies one thread slot. DLR and DDN tasks continue to occupy one thread per task.
+
+- [`setDeviceFriendlyName()`]({{ site.dcvb_java_api }}license/license-manager.html#setdevicefriendlyname) now enforces parameter constraints: maximum 64 characters, allowed characters are letters (a-z, A-Z), digits (0-9), hyphen (-), underscore (_), and period (.), and must start and end with a letter or digit. Returns [`EC_PARAMETER_VALUE_INVALID`]({{ site.dcvb_java_api }}core/enum-error-code.html) if constraints are not met.
+
+- The Linux ARM64 minimum requirement is now glibc 2.27 (Ubuntu 18.04+, Debian 10+, and CentOS/RHEL 8+).
+
+- Removed the VC++ Redistributable runtime dependency for the JNI DLL on Windows (runtime linkage changed from MD to MT).
+
+### Improved
+
+- Updated `MRZLocalization.data` model for improved portrait zone detection accuracy.
+
+- [`findPortraitZone()`]({{ site.dcvb_java_api }}id-utility/identity-processor.html#findportraitzone) now returns the portrait zone quadrilateral with the top-left corner of the upright portrait as the first point.
+
+- Improved `idNumberType` field extraction accuracy for `SOUTH_AFRICA_DL` parsing.
+
+### Fixed
+
+- Fixed a crash that could occur in AWS Lambda environments under certain conditions.
+
+- Fixed an issue in GS1-Databar AI `17` (YYMMDD) results where the month field could be missing a leading zero.
+
+### Deprecations
+
+- Marked `PDFRM_VECTOR` as deprecated (covered by [`PDFRM_MULTIMODAL`]({{ site.dcvb_java_api }}core/enum-pdf-reading-mode.html)).
+
 ## 3.4.3000 (06/30/2026)

 # Release Notes for Python Edition - 3.x
 
+## 3.6.1000 (07/23/2026)
+
+### Highlights
+
+#### Multimodal PDF Content Extraction
+
+- **New PDF Reading Mode** - Added [`PDFRM_MULTIMODAL`]({{ site.dcvb_python_api }}core/enum-pdf-reading-mode.html) to [`PDFReadingMode`]({{ site.dcvb_python_api }}core/enum-pdf-reading-mode.html), now the default for [`PDFReadingParameter`]({{ site.dcvb_python_api }}core/basic-classes/pdf-reading-parameter.html). It extracts vector graphics, text content, and embedded images from PDF files, enabling stronger barcode reading performance in multimodal PDF scenarios.
+- **Performance Behavior Update** - Compared with full-page raster rendering, [`PDFRM_MULTIMODAL`]({{ site.dcvb_python_api }}core/enum-pdf-reading-mode.html) usually improves speed by avoiding unnecessary rendering of irrelevant regions.
+
+#### Multi-Threaded Barcode Decoding
+
+- **Get results sooner with parallel processing** - Barcode decoding now uses a breadth-first strategy that decomposes a single DBR Task into one Localization Work and one or more Decoding Works. This improves thread utilization and reduces the chance that a slow `DeblurMode` attempt blocks other faster decoding attempts, helping valid results come back sooner.
+
+#### DataMatrix Color Inversion Detection
+
+- **Handle normal and inverted DataMatrix more efficiently** - Added [`AutoDetectColorInversion`]({{ site.dcvb_parameters_reference }}barcode-format-specification/auto-detect-color-inversion.html) to automatically handle both normal and inverted DataMatrix barcodes. Instead of processing the whole image twice, the SDK applies dual-polarity handling only to localized DataMatrix regions, which makes processing faster in dual-polarity scenarios.
+
+#### Barcode Layout Analysis
+
+- **Decode dense grid barcodes more completely** - Added [`LayoutAnalyzer`]({{ site.dcvb_python_api }}utility/layout-analyzer.html) to organize barcode locations into logical line or matrix layouts and infer unrecognized barcode regions when gaps exist, enabling workflows such as fast first-pass decoding, missing-region inference, and targeted second-pass decoding on dense N*M barcode layouts.
+
+#### Cross-Version License Support
+
+- **Use a single license across SDK versions** - Full License 1.0 keys (starting with "f") that are non-perpetual are no longer version-checked, so the same key can be used across SDK versions without reactivation.
+
+#### Text Line Orientation Detection
+
+- **Support text lines in arbitrary orientations more automatically** - Added [`OrientationDetectionModes`]({{ site.dcvb_parameters_reference }}label-recognizer-task-settings/orientation-detection-modes.html) to automatically detect text line orientation and correct the orientation of text lines for further processing. Two modes are available: `ODM_SPATIAL_REFERENCES` and `ODM_CHARS_ORIENTATION_NEURAL_NETWORK`.
+
+### New
+
+- Added [`PDFRM_MULTIMODAL`]({{ site.dcvb_python_api }}core/enum-pdf-reading-mode.html) value to [`PDFReadingMode`]({{ site.dcvb_python_api }}core/enum-pdf-reading-mode.html) enumeration for multimodal PDF content extraction.
+
+- Added [`AutoDetectColorInversion`]({{ site.dcvb_parameters_reference }}barcode-format-specification/auto-detect-color-inversion.html) parameter for `BarcodeFormatSpecification` to support automatic color-inversion detection for DataMatrix barcodes.
+
+- Added a new overload of [`capture_multi_pages()`]({{ site.dcvb_python_api }}capture-vision-router/single-file-processing.html#capture_multi_pages) that accepts a [`FileFetcher`]({{ site.dcvb_python_api }}utility/file-fetcher.html) parameter for more flexible file input handling.
+
+- Added [`LayoutAnalyzer`]({{ site.dcvb_python_api }}utility/layout-analyzer.html) class with [`analyze()`]({{ site.dcvb_python_api }}utility/layout-analyzer.html#analyze) static method for quadrilateral layout analysis.
+
+- Added [`LayoutPattern`]({{ site.dcvb_python_api }}utility/enum-layout-pattern.html) enumeration with values `LP_UNKNOWN`, `LP_LINES`, and `LP_MATRIX`.
+
+- Added [`LayoutElementSource`]({{ site.dcvb_python_api }}utility/enum-layout-element-source.html) enumeration with values `LES_NONE`, `LES_INPUT`, and `LES_INFERRED`.
+
+- Added [`MeasureUnit`]({{ site.dcvb_python_api }}core/enum-measure-unit.html) enumeration with values `MU_PIXEL` and `MU_PERCENTAGE`.
+
+- Added structures [`LayoutAxis`]({{ site.dcvb_python_api }}utility/layout-axis.html), [`LayoutAnalysisParameter`]({{ site.dcvb_python_api }}utility/layout-analysis-parameter.html), [`LayoutElement`]({{ site.dcvb_python_api }}utility/layout-element.html), and [`LayoutAnalysisResult`]({{ site.dcvb_python_api }}utility/layout-analysis-result.html) for layout analysis configuration and results.
+
+- Added a new `GridBarcodeScanner` sample (with `sample_grid.png`) to demonstrate how to use [`LayoutAnalyzer`]({{ site.dcvb_python_api }}utility/layout-analyzer.html) for barcode grid layout detection and logical row/column mapping.
+
+- Added [`OrientationDetectionModes`]({{ site.dcvb_parameters_reference }}label-recognizer-task-settings/orientation-detection-modes.html) parameter for the [`SST_LOCALIZE_TEXT_LINES`]({{ site.dcvb_parameters_reference }}label-recognizer-task-settings/stage-localize-text-lines.html) stage with two supported modes: `ODM_SPATIAL_REFERENCES` and `ODM_CHARS_ORIENTATION_NEURAL_NETWORK`.
+
+- Added `TextLineOrientationCls.data` model file for text line orientation classification.
+
+### Changed
+
+- Default [`PDFReadingMode`]({{ site.dcvb_python_api }}core/enum-pdf-reading-mode.html) in [`PDFReadingParameter`]({{ site.dcvb_python_api }}core/basic-classes/pdf-reading-parameter.html) constructor changed from [`PDFRM_RASTER`]({{ site.dcvb_python_api }}core/enum-pdf-reading-mode.html) to [`PDFRM_MULTIMODAL`]({{ site.dcvb_python_api }}core/enum-pdf-reading-mode.html).
+
+- [`MaxParallelTasks`]({{ site.dcvb_parameters_reference }}capture-vision-template/max-parallel-tasks.html) now controls the total number of concurrent Work threads in the CVR thread pool. For DBR tasks, each Localization Work and Decoding Work occupies one thread slot. DLR and DDN tasks continue to occupy one thread per task.
+
+- [`set_device_friendly_name()`]({{ site.dcvb_python_api }}license/license-manager.html#set_device_friendly_name) now enforces parameter constraints: maximum 64 characters, allowed characters are letters (a-z, A-Z), digits (0-9), hyphen (-), underscore (_), and period (.), and must start and end with a letter or digit. Returns [`EC_PARAMETER_VALUE_INVALID`]({{ site.dcvb_python_api }}core/enum-error-code.html) if constraints are not met.
+
+- The Linux ARM64 minimum requirement is now glibc 2.27 (Ubuntu 18.04+, Debian 10+, and CentOS/RHEL 8+).
+
+### Improved
+
+- Updated `MRZLocalization.data` model for improved portrait zone detection accuracy.
+
+- [`find_portrait_zone()`]({{ site.dcvb_python_api }}id-utility/identity-processor.html#find_portrait_zone) now returns the portrait zone quadrilateral with the top-left corner of the upright portrait as the first point.
+
+- Improved `idNumberType` field extraction accuracy for `SOUTH_AFRICA_DL` parsing.
+
+### Fixed
+
+- Fixed a crash that could occur in AWS Lambda environments under certain conditions.
+
+- Fixed an issue in GS1-Databar AI `17` (YYMMDD) results where the month field could be missing a leading zero.
+
+### Deprecations
+
+- Marked `PDFRM_VECTOR` as deprecated (covered by [`PDFRM_MULTIMODAL`]({{ site.dcvb_python_api }}core/enum-pdf-reading-mode.html)).
+
