Fixed a potential race condition edge case in CryoSPARC Live session compaction that could cause unintended deletion of additional files outside the session directory. **Users of versions v5.0.0-v5.0.7 should not use the [session compaction tool](https://guide.cryosparc.com/setup-configuration-and-management/software-system-guides/guide-data-cleanup-v4.3#compacting-a-live-session)** and should upgrade to v5.0.8.

Cleanup Data tool no longer clears final preprocessing jobs when both "Include final ancestor jobs" and "Clear non-final jobs" are selected.

Attaching a project containing jobs with unrecognized result data types no longer fails.

Very large Workflow JSON files no longer fail to import.

Updated dependency package version of `brotli` compression library to address CVE-2026-111497.
