Written by AI from the official notes. Check them for exact details.

New features include full-screen diffs for file creations and improvements to OAuth print mode. Lag issues have also been addressed.

Added full-screen diffs for file creations with an 'f' shortcut.
Improved OAuth code pasting in print mode for headless runs.
Enhanced responsiveness for large conversations, reducing CPU lag.
Fixed print mode model resolution issues with actionable error messages.
Resolved permission check issues for nested command substitutions.

Why it matters: Users relying on file creation and OAuth features should update to benefit from improved performance and usability.

Added full-screen diffs for file creations, OAuth authorization code pasting in print mode, and 5000+ step latency optimizations.

Added an f (full diff) shortcut to the create-file tool review screen so new-file confirmations can open a full-screen diff view, matching the existing file-edit experience.
Added support for pasting the OAuth authorization code in print mode (-p) via the controlling terminal (/dev/tty on POSIX and CONIN$ on Windows) when stdin is consumed by a piped prompt, and made truly headless runs fail fast with an actionable message instead of blocking.
Improved responsiveness on large conversations (5000+ steps) in no flickering mode by switching hot-path line-count methods to pointer receivers, cutting the per-frame prefix-sum cost and eliminating sustained 99% CPU and keystroke lag.
Fixed print mode silently downgrading to the default model when --model cannot be resolved by hard-failing with a non-zero exit and listing the available models, while interactive sessions keep the fallback-with-warning behavior.
Fixed permission checks not respecting the allowlist for nested command substitutions, so a command like echo "$(dirname $(git rev-parse --show-toplevel))" now runs without prompting when echo and git are allowlisted, instead of double-counting the nested command and prompting for review.
Fixed the CLI keybindings file staying out of sync with /keybindings when new default bindings are introduced by persisting the injected defaults while preserving user overrides.
Fixed garbled builtin tool headers such as CodeSearch(4 files found...) by mapping generic tool steps back to clean summaries like Read(/path) and CodeSearch(query).
Fixed mcp manager failing to resolve tool schema paths in standalone mode and leaking MCP server subprocesses after shutdown, which previously caused panics and cleanup failures for custom agents loading MCP tools.
Fixed a data race and copy-on-write violation when updating subagent states by cloning their stats before in-place mutation, preventing corrupted step counts and status for parallel subagents.
