@@ -118,6 +118,7 @@ Docs: https://docs.openclaw.ai
 - Gateway/session stores: regenerate the Swift push-test protocol models and align Windows native session-store realpath handling so protocol checks and sync session discovery stop drifting on Windows. (#44266) thanks @jalehman.
 - Context engine/session routing: forward optional `sessionKey` through context-engine lifecycle calls so plugins can see structured routing metadata during bootstrap, assembly, post-turn ingestion, and compaction. (#44157) thanks @jalehman.
 - Agents/failover: classify z.ai `network_error` stop reasons as retryable timeouts so provider connectivity failures trigger fallback instead of surfacing raw unhandled-stop-reason errors. (#43884) Thanks @hougangdev.
+- Config/Anthropic startup: inline Anthropic alias normalization during config load so gateway startup no longer crashes on dated Anthropic model refs like `anthropic/claude-sonnet-4-20250514`. (#45520) Thanks @BunsDev.
 - Memory/session sync: add mode-aware post-compaction session reindexing with `agents.defaults.compaction.postIndexSync` plus `agents.defaults.memorySearch.sync.sessions.postCompactionForce`, so compacted session memory can refresh immediately without forcing every deployment into synchronous reindexing. (#25561) thanks @rodrigouroz.
 - Telegram/model picker: make inline model button selections persist the chosen session model correctly, clear overrides when selecting the configured default, and include effective fallback models in `/models` button validation. (#40105) Thanks @avirweb.
 - Telegram/native command sync: suppress expected `BOT_COMMANDS_TOO_MUCH` retry error noise, add a final fallback summary log, and document the difference between command-menu overflow and real Telegram network failures.
