 ### Bugs Fixed
 
+- [[#7223]](https://github.com/Azure/azure-dev/pull/7223) Improve `.funcignore` handling for flex-consumption function apps by inferring `remoteBuild` from file contents and failing fast on incompatible configurations.
 - [[#7274]](https://github.com/Azure/azure-dev/pull/7274) Revert env-flag change from v1.23.11 to fix regression where the `-e` shorthand for `--environment` conflicted with extension commands that use `-e` for their own flags (e.g., `--project-endpoint` in `azure.ai.models` and `azure.ai.finetune`), restoring compatibility with those extensions.
