@@ -78,6 +78,7 @@ Status: beta.
 - Web UI: auto-expand the chat compose textarea while typing (with sensible max height). (#2950) Thanks @shivamraut101.
 - Gateway: prevent crashes on transient network errors (fetch failures, timeouts, DNS). Added fatal error detection to only exit on truly critical errors. Fixes #2895, #2879, #2873. (#2980) Thanks @elliotsecops.
 - Agents: guard channel tool listActions to avoid plugin crashes. (#2859) Thanks @mbelinky.
+- Providers: update MiniMax API endpoint and compatibility mode. (#3064) Thanks @hlbbbbbbb.
 - Gateway: suppress AbortError and transient network errors in unhandled rejections. (#2451) Thanks @Glucksberg.
 - TTS: keep /tts status replies on text-only commands and avoid duplicate block-stream audio. (#2451) Thanks @Glucksberg.
 - Security: pin npm overrides to keep tar@7.5.4 for install toolchains.
