@@ -126,6 +126,10 @@ Docs: https://docs.openclaw.ai
 - Telegram/network: preserve sticky IPv4 fallback state across polling restarts so hosts with unstable IPv6 to `api.telegram.org` stop re-triggering repeated Telegram timeouts after each restart. (#48282) Thanks @yassinebkr.
 - Plugins/subagents: forward per-run provider and model overrides through gateway plugin subagent dispatch so plugin-launched agent delegations honor explicit model selection again. (#48277) Thanks @jalehman.
 - Agents/compaction: write minimal boundary summaries for empty preparations while keeping split-turn prefixes on the normal path, so no-summarizable-message sessions stop retriggering the safeguard loop. (#42215) thanks @lml2468.
+- Models/chat commands: keep `/model ...@YYYYMMDD` version suffixes intact by default, but still honor matching stored numeric auth-profile overrides for the same provider. (#48896) Thanks @Alix-007.
+
+### Fixes
+
 - Agents/bootstrap warnings: move bootstrap truncation warnings out of the system prompt and into the per-turn prompt body so prompt-cache reuse stays stable when truncation warnings appear or disappear. (#48753) Thanks @scoootscooob and @obviyus.
 - Telegram/DM topic session keys: route named-account DM topics through the same per-account base session key across inbound messages, native commands, and session-state lookups so `/status` and thread recovery stop creating phantom `agent:main:main:thread:...` sessions. (#48204) Thanks @vincentkoc.
 - macOS/node service startup: use `openclaw node start/stop --json` from the Mac app instead of the removed `openclaw service node ...` command shape, so current CLI installs expose the full node exec surface again. (#46843) Fixes #43171. Thanks @Br1an67.
