What's new:

• Added support for Claude Sonnet 4.6 and Claude Sonnet 4.6 (1M) (1 million token context window variant). They’re smarter than Sonnet 4.5, at the same price.

• Support deleting unused Knowledge Base tags

  

Bug fixes & improvements:

• Fixed the "Use now" button in the Prompts Library page not working on the first click.

• Fixed attachment rendering for clipboard-pasted/legacy attachments, preventing "No valid blob source" errors.

• Fixed the copy button under messages not working correctly in some cases; text extraction now includes all text blocks instead of only the first match, preventing incomplete/empty copied content.

• Fixed errors caused by empty content: [] arrays in assistant messages during OpenAI response transformation/streaming.
