v1.18.0

Added

• Added CustomInstructions property to TextTranslateOptions to customize translation behavior with up to 10 instructions (max 300 characters each). Only supported for target languages: de, en, es, fr, it, ja, ko, zh and their variants. Note: using the CustomInstructions parameter will use quality_optimized model type as the default. Requests combining CustomInstructions and the LatencyOptimized model type will be rejected.

v1.17.0

Added

• Added support for style rules in text translation via the StyleId property in TextTranslateOptions.
• Added GetAllStyleRulesAsync() method to DeepLClient to retrieve all available style rules with optional pagination and detailed configuration.
• Added new model classes: StyleRuleInfo, ConfiguredRules, and CustomInstruction to support style rules functionality.

v1.16.0

Added

• Added ExtraBodyParameters option to text and document translation methods to pass arbitrary parameters in the request body. This can be used to access beta features or override built-in parameters (such as target_lang, source_lang, etc.).

v1.15.0

Added

• Added support for the /v3 Multilingual Glossary APIs in the client library while providing backwards compatability for the previous /v2 Glossary endpoints. Please refer to the README or upgrading_to_multilingual_glossaries.md for usage instructions.

v1.14.0

Added

• Added support for the output_format parameter when translating documents.
  • #50 thanks for JuergenRB

v1.13.0

Added

• Added support for the Write API in the client library, the implementation
  can be found in the DeepLClient class. Please refer to the README for usage
  instructions.

Fixed

• Fixed code example for getting glossary entries in the README
  • #58 thanks to KurtBildeSDU

Changed

• The main functionality of the library is now also exposed via the DeepLClient
  class. Please change your code to use this over the Translator class whenever
  convenient.

v1.12.0

Added

• Added document minification as a feature before document translation, to
  allow translation of large docx or pptx files. For more info check the README.
• Note that there might be a small delay with the nuget package release.

v1.11.0

Added

• Added ModelType option for text translation to use models with higher
  translation quality (available for some language pairs), or better latency.
  Options are:
  • ModelType.QualityOptimized ('quality_optimized'),
  • ModelType.QualityOptimized ('latency_optimized'), and
  • ModelType.QualityOptimized ('prefer_quality_optimized')
• Added the ModelTypeUsed field to text translation response, that
  indicates the translation model used when the ModelType option is
  specified.

v1.10.0

Added

• Added BilledCharacters to the translate text response.

v1.9.0

Added

• New language available: Arabic (MSA) ('ar'). Add language code constants and tests.

  Note: older library versions also support the new language, this update only
  adds new code constants.

  • #44 thanks to Ilmalte

Fixed

• Change document upload to use the path /v2/document instead of /v2/document/ (no trailing /).
  Both paths will continue to work in the v2 version of the API, but /v2/document is the intended one.
• Made DeepLException and subclasses, Usage and JsonFieldsStruct constructors public, to allow for easier mocking of the ITranslator interface.
