Oct 1, 2025October 2025 (HTCondor) monthly summary for htcondor/htcondor focused on storage management, release engineering, and test infrastructure. Delivered Volume Manager storage management and LVM reporting enhancements with robust handling for hyphenated LVM device names, proper escaping, improved LVM path construction (doubling hyphens), and refined total disk space reporting that separates detected, free, and non-Condor space. Cleaned up release notes and version history documentation across v25 series to improve clarity and consistency. Strengthened testing infrastructure for job submission tests by refactoring test_job_submit_method_recording.py to speed up tests and reduce flakiness through helper utilities and structured testing across HTCondor submission tools.
