v1.4.5

Added

• Translate the browser interface from JSON catalogs. Every file under web/src/locales is a language, so a fork adds one by dropping a file there and running make ui. The choice is stored in the m365bridge_lang cookie, English is the default, and a language the build does not carry resolves to English and rewrites the cookie
• Render an answer and its reasoning block as markdown, so a comparison table is a table and a citation is a link rather than a bare URL in the middle of a sentence. A user message stays literal
• Give every conversation its own address, /c/{session id}, so it can be reloaded onto, linked to, and reached with the browser's back and forward buttons
• Ask for a rename or a delete inside the page instead of through the browser's own dialogs
• Read the session id an agent client stamps on its request: X-Claude-Code-Session-Id from Claude Code and Session-Id from Codex, both below any session the caller names explicitly
• Accept stop on /v1/chat/completions and /v1/completions, and stop_sequences on /v1/messages and /v1/complete, on both the streaming and the non-streaming paths
• Report the stop sequence that ended a completion, as null rather than an empty string when the answer ended on its own
• Honour parallel_tool_calls: false and disable_parallel_tool_use by returning a single tool call

Fixed

• Store a session's conversation before writing the end of a response, never after. A client that read the terminator and asked about its session at once was told the session does not exist, which made the browser interface show one conversation as two rows
• Delete a conversation on both sides whichever side starts, and clear every session bound to it, because more than one session can point at one conversation
• Keep each column's scrollbar inside its own column in the browser interface; a long conversation used to scroll the whole page and the sidebar list never scrolled on its own
• Report created_at on every Responses lifecycle event
• Read a bare url under an image_url or input_image block, which is the form several clients send
• Carry a developer message as instructions, the role OpenAI's reasoning models use in place of system
• Honour a json_schema response format
• End a completion at its stop sequence, including a sequence split across two upstream chunks
• Stop reading an answer that discusses sandboxes as a refusal
• Bound the request body every handler reads and every upstream response body this proxy reads
• Replace every state file in one step instead of truncating it, so a failed write cannot leave a half-written credential store
• Cut text on a rune boundary wherever a byte cap applies
• Report a response body that failed to encode instead of sending a truncated one

Changed

• Resolve every request's session through one order, so /v1/completions, /v1/messages and /v1/complete read session_id and user from the body like the other endpoints
• Cut text on a character boundary from one place rather than at each call site
• Drop the unused scoped token exchange from the authentication layer
• Remove the dependabot configuration
• Rewrite both READMEs against the running service: the Go floor, the package list, the Anthropic SDK base URL, the capability tree shape, the MCP tool arguments, the image backend name, 413 request_too_large, and what an unserved model name returns
