v1.8.5 - Spanish Locale & Token-Based Chunking

on GitHub

Highlights

• 🇪🇸 Spanish (es-ES) language support with full translation coverage
• Token-based embedding chunking — better handling of CJK and mixed-language content
• Resilient credential handling — broken/mismatched encryption keys no longer crash the API

Added

• Spanish (es-ES) locale with 930+ translation keys and language toggle entry (#757) — thanks @chemazener!

Changed

• Embedding chunking is now token-based instead of character-based, improving chunk sizing consistency for CJK and mixed-language content (#542, #749) — thanks @unendless314!
• OPEN_NOTEBOOK_CHUNK_SIZE and OPEN_NOTEBOOK_CHUNK_OVERLAP semantics changed from characters to tokens; default reduced from 1200 characters to 400 tokens to stay safely below the 512-token ceiling of BERT-family embedders (e.g. mxbai-embed-large). Existing stored embeddings are unaffected — only new ingestions use the new chunking.
• Internal: migrated i18n from the custom Proxy pattern to standard react-i18next t() function for better tooling compatibility (#755)

Fixed

• Credentials endpoint no longer crashes (500) when the encryption key doesn't match stored credentials (#740, #753)
• Broken credentials are now shown with a decryption warning and can still be deleted
• DELETE endpoint for broken credentials supports model migration via the migrate_to parameter
• Azure credentials: base_url now correctly maps to endpoint (#741)

Docs

• Improved local quick-start documentation (#734) — thanks @vincentrou!
