Copilot CLI v1.0.52-2: Context Window Enforcement & Token Display
Copilot CLI 1.0.52-2 enforces context window tier selection end-to-end, fixes AI Credits display after Responses API sessions, and resolves tmux rendering stutter on Cygwin/mintty.
TL;DR
- Context window tier selection now actually enforced end-to-end across compaction and truncation
- Reasoning tokens now display inline with output token count
- Fixed AI Credits display after Responses API sessions and tmux rendering stutter
New
- Context window tier enforcement — Picking between ~200K and 1M token tiers now constrains compaction, truncation, and token display consistently across the CLI
Improved
- Reasoning token display — Reasoning tokens now show as a parenthetical on the output token count in the token usage summary, making it clearer what you're actually consuming
Fixed
- AI Credits usage now displays correctly after sessions using the Responses API
- Rendering no longer stutters when using tmux on Cygwin or mintty
- Slash command picker keeps experimental and staff labels orange when the row is selected
Update with: gh copilot update
