Public API changes and backwards compatibility

This section lists all public API changes introduced in Aspose.OCR for C++ 26.8.0 that may affect the code of existing applications.

Added public APIs:

The following public APIs have been introduced in this release:

`language::latin`

Uses the new Latin OCR model for recognizing Latin-script text.

`language::ext_latin`

Uses the extended Latin alphabet with the legacy recognition model. Set this language explicitly if your application needs the previous extended Latin recognition behavior.

`detect_areas_mode_enum::UNIVERSAL`

Adds a universal areas detection mode.

Updated public APIs:

`RecognitionSettings::language_alphabet`

The default recognition language has been changed to language::latin.

To keep the previous extended Latin recognition behavior, explicitly set RecognitionSettings::language_alphabet to language::ext_latin.

`detect_areas_mode_enum`

The following area detection mode values have been renamed:

Old value	New value
`detect_areas_mode_enum::NONE`	`detect_areas_mode_enum::LEAN`
`detect_areas_mode_enum::DOCUMENT`	`detect_areas_mode_enum::MULTICOLUMN`

The numeric values are preserved: LEAN = 0, MULTICOLUMN = 1.

Removed public APIs:

The following area detection mode names have been removed:

detect_areas_mode_enum::NONE
detect_areas_mode_enum::DOCUMENT

Package changes

The Windows CPU NuGet package includes ONNX Runtime 1.22.1 binaries.
The Windows GPU NuGet package depends on Microsoft.ML.OnnxRuntime.Gpu.Windows 1.18.1 and requires the matching NVIDIA CUDA runtime dependencies on the target machine.
