 ## [Unreleased]
 
+### New Features
+
+- Extension handlers can now use `ctx.signal` to forward cancellation into nested model calls, `fetch()`, and other abort-aware work. See [docs/extensions.md#ctxsignal](docs/extensions.md#ctxsignal) ([#2660](https://github.com/badlogic/pi-mono/issues/2660))
+- Built-in `edit` tool input now uses `edits[]` as the only replacement shape, reducing invalid tool calls caused by mixed single-edit and multi-edit schemas ([#2639](https://github.com/badlogic/pi-mono/issues/2639))
+- Large multi-edit results no longer trigger full-screen redraws in the interactive TUI when the final diff is rendered ([#2664](https://github.com/badlogic/pi-mono/issues/2664))
+
 ### Added
 
 - Added `ctx.signal` to `ExtensionContext` and wired it to the active agent turn so extension handlers can forward cancellation into nested model calls, `fetch()`, and other abort-aware work ([#2660](https://github.com/badlogic/pi-mono/issues/2660))
 
 ### Fixed
 
+- Fixed built-in `edit` tool input to use `edits[]` as the only replacement shape, eliminating the mixed single-edit and multi-edit modes that caused repeated invalid tool calls and retries ([#2639](https://github.com/badlogic/pi-mono/issues/2639))
 - Fixed edit tool TUI rendering to defer large multi-edit diffs to the settled result, avoiding full-screen redraws when the tool completes ([#2664](https://github.com/badlogic/pi-mono/issues/2664))
