 ## [Unreleased]
 
+### New Features
+
+- Extensions and SDK callers can attach a `prepareArguments` hook to any tool definition, letting them normalize or migrate raw model arguments before schema validation. The built-in `edit` tool uses this to transparently support sessions created with the old single-edit schema. See [docs/extensions.md](docs/extensions.md)
+
 ### Breaking Changes
 
 - `ModelRegistry` no longer has a public constructor. SDK callers and tests must use `ModelRegistry.create(authStorage, modelsJsonPath?)` for file-backed registries or `ModelRegistry.inMemory(authStorage)` for built-in-only registries. Direct `new ModelRegistry(...)` calls no longer compile.

 ### Fixed
 
-- Fixed extension-queued user messages to refresh the interactive pending-message list while preserving `input` event source semantics for `pi.sendUserMessage()` ([#2674](https://github.com/badlogic/pi-mono/pull/2674) by [@mrexodia](https://github.com/mrexodia))
+- Fixed extension-queued user messages to refresh the interactive pending-message list so messages submitted while a turn is active are no longer silently dropped ([#2674](https://github.com/badlogic/pi-mono/pull/2674) by [@mrexodia](https://github.com/mrexodia))
+- Fixed monorepo `tsconfig.json` path mappings to resolve `@mariozechner/pi-ai` subpath exports to source files in development checkouts ([#2625](https://github.com/badlogic/pi-mono/pull/2625) by [@ferologics](https://github.com/ferologics))
+- Fixed TUI cell size response handling to consume only exact `CSI 6 ; height ; width t` replies, so bare `Escape` is no longer swallowed while waiting for terminal image metadata ([#2661](https://github.com/badlogic/pi-mono/issues/2661))
