 # Optimizely Python SDK Changelog
 
+## 5.8.0
+October 30th, 2026
+
+### Changed
+
+**Local Holdouts: rule evaluation continues after a holdout hit**: 
+When a user matches a local holdout on a rule, the SDK now excludes the user from that rule only 
+and continues evaluating the remaining rules, instead of returning the holdout variation and skipping 
+the rest of the flag. Each local holdout hit sends its own holdout impression event (using the 
+existing event format), regardless of `sendFlagDecisions`. Global holdouts are unchanged.
+
+- Continue rule evaluation after local holdout hit ([#525](https://github.com/optimizely/python-sdk/pull/525))
+- Remove dead Python 3.7 typing guards ([#526](https://github.com/optimizely/python-sdk/pull/526))
