 - Security/external content: treat whitespace-delimited `EXTERNAL UNTRUSTED CONTENT` boundary markers like underscore-delimited variants so prompt wrappers cannot bypass marker sanitization. (#35983) Thanks @urianpaul94.
 - Telegram/network env-proxy: apply configured transport policy to proxied HTTPS dispatchers as well as direct `NO_PROXY` bypasses, so resolver-scoped IPv4 fallback and network settings work consistently for env-proxied Telegram traffic. (#40740) Thanks @sircrumpet.
 - Agents/memory flush: forward `memoryFlushWritePath` through `runEmbeddedPiAgent` so memory-triggered flush turns keep the append-only write guard without aborting before tool setup. Follows up on #38574. (#41761) Thanks @frankekn.
+- CI/CodeQL Swift toolchain: select Xcode 26.1 before installing Swift build tools so the CodeQL Swift job uses Swift tools 6.2 on `macos-latest`. (#41787) thanks @BunsDev.
