4.8.8

Bug Fixes

• Fixed an issue that could have caused some timers, like the one responsible for Symbol Database uploads, to fire repeatedly after the first execution.

• internal: This fix resolves a memory leak where reference cycles through PeriodicThread callbacks were invisible to Python's cyclic garbage collector and could accumulate when threads used bound methods as targets.

• profiling: Fixes a memory leak in native frame tracking caused by unbounded native call-site metadata growth.

• SCA: This fix resolves an issue where unresolved runtime reachability targets could accumulate across Software Composition Analysis updates, causing resident memory usage to grow over time.

• sqlalchemy: Fixes duplicate SQLAlchemy event listeners when trace_engine() is called repeatedly for the same engine.

• dynamic instrumentation: fixes an issue where the Symbol Database uploader sends empty payloads on a recurring timer.
