June 2025 — Azure/telescope: Delivered one bug fix and one feature, strengthening build reliability and governance. Key changes include a default for SKIP_RESOURCE_DELETION to prevent unbound variable errors during builds, plus a fail-fast guard when SKIP_RESOURCE_DELETION is true for Manual builds, prompting manual resource deletion. Also clarified CCP-owned pipeline ownership by updating CODEOWNERS, defining responsibility for performance evaluation and scheduler benchmark configurations. These changes reduce production risk, improve triage speed, and enhance cross-team accountability. Commits: c17dbfc85364ad6d58c1bc13e81f7aa066bfd14b; 409db26eadd10e9c1a22bfd78f1a5d7caa63783f.
