 - Slack/runtime defaults: trim Slack DM reply overhead, restore Codex auto transport, and tighten Slack/web-search runtime defaults around DM preview threading, cache scoping, warning dedupe, and explicit web-search opt-in. (#53957) Thanks @vincentkoc.
 - Discord/timeouts: send a visible timeout reply when the inbound Discord worker times out before a final reply starts, including created auto-thread targets and queued-run ordering. (#53823) Thanks @Kimbo7870.
 - Models/google: normalize bare Google Generative AI API roots for custom provider names, and keep built-in Google model-id rewrites working when `api` is declared only on individual models, so custom Google lanes and older configs stop missing `/v1beta` or preview-id normalization. (#44969) Thanks @Kathie-yu.
+- Gateway/ports: parse Docker Compose-style `OPENCLAW_GATEWAY_PORT` host publish values correctly without reviving the legacy `CLAWDBOT_GATEWAY_PORT` override. (#44083) Thanks @bebule.
