Release Notes

2026-10-01 - Add copilot sandbox ca commands to check, create, trust, rotate, and remove proxy CA trust, including unattended Windows setup; /sandbox ca install becomes create and trust - Session timelines now clear busy status after interrupted turns finish. - Sandboxed commands run on Windows versions without filesystem enumeration support, with a warning that PowerShell's current location may be wrong - Footer text selection stays on the same visible line when the footer grows or shrinks. - Offer sandbox network bypass for Node/npm EACCES socket denials on Windows - CLI shutdown flushes pending telemetry before exit, with a bounded delay when telemetry is still initializing. - Complete, statically analyzable read-only shell pipelines can now enter execution-evidence review, while incomplete or unbound pipelines require explicit approval.
