v1.20.0

[1.20.0] - 2026-08-11

Added

• Added support for using multiple glossaries in text and document translation
  via the TranslateTextOptions::GLOSSARY_IDS and
  TranslateDocumentOptions::GLOSSARY_IDS options (up to 5 glossary IDs).
• Added support for style rules in document translation via the
  TranslateDocumentOptions::STYLE_ID option.
• Added support for translation memories in document translation via the
  TranslateDocumentOptions::TRANSLATION_MEMORY_ID and
  TranslateDocumentOptions::TRANSLATION_MEMORY_THRESHOLD options.
• Added support for the translation memory management endpoints in the
  DeepLClient class: getTranslationMemory(),
  listTranslationMemorySegments(), deleteTranslationMemory(),
  createTranslationMemoryImport(), uploadTranslationMemoryFile(),
  createTranslationMemoryExport(), getTranslationMemoryJob(),
  waitUntilTranslationMemoryJobDone(), downloadTranslationMemoryExport(),
  importTranslationMemoryFromFilepath() and
  exportTranslationMemoryToFilepath().
  waitUntilTranslationMemoryJobDone() polls through the 'awaiting_input'
  status, which an import job keeps reporting for a while after its file has
  been uploaded, and accepts an optional timeout in seconds, as do
  importTranslationMemoryFromFilepath() and
  exportTranslationMemoryToFilepath().
• Added new model classes TranslationMemorySegment,
  TranslationMemoryTargetSegment, TranslationMemorySegments,
  TranslationMemorySegmentsOptions, TranslationMemoryImport,
  TranslationMemoryExport, TranslationMemoryJob and
  TranslationMemoryJobResult.
• Added the creationTime and updatedTime properties to
  TranslationMemoryInfo.

Changed

• Requests to the pre-signed storage URLs used for translation memory import and export now
  go through a separate HTTP client that is constructed without the DeepL Authorization
  header, instead of stripping it per request. Headers supplied via TranslatorOptions::HEADERS
  are no longer sent to those URLs either — only the User-Agent and the per-request
  Content-Type. Proxy settings are unaffected.
