enhancementReview CHANGELOG before upgrading
The release notes published here are sparse. Before rolling this out, pull the full CHANGELOG-3.5.md directly from the etcd repo to identify any bug fixes or behavioral changes that affect your cluster. Patch releases on 3.5 have historically included compaction fixes and lease handling improvements — worth verifying what specifically landed here.
breakingCheck the upgrade guide even for patch versions
The etcd team explicitly calls out that breaking changes can appear in patch releases. Don't skip the upgrade guide assuming this is safe to apply blindly. Verify any API or storage format changes against your current deployment before scheduling maintenance.
