 ## [Unreleased]
 
+### New Features
+
+- **Extension compaction event context** - Extension `session_before_compact` and `session_compact` events now include `reason` and `willRetry`, so extensions can distinguish manual `/compact`, threshold auto-compaction, and overflow retry flows. See [session_before_compact / session_compact](docs/extensions.md#session_before_compact--session_compact) and [Custom Summarization via Extensions](docs/compaction.md#custom-summarization-via-extensions).
+- **Safer update flow** - `pi update` installs the exact checked Pi version, and update notices show the changelog URL, making upgrades more predictable. See [Install and Manage](docs/packages.md#install-and-manage).
+
+### Added
+
+- Added `reason` and `willRetry` metadata to extension `session_before_compact` and `session_compact` events so extensions can distinguish manual, threshold, and overflow compaction flows ([#5962](https://github.com/earendil-works/pi/pull/5962) by [@PizzaMarinara](https://github.com/PizzaMarinara)).
+
 ### Fixed
 
 - Fixed the `find` tool to respect nested git repository boundaries when parent `.gitignore` rules ignore the nested repo ([#5960](https://github.com/earendil-works/pi/issues/5960)).
 - Fixed the usage docs slash command table to include `/trust` and `/import` ([#5959](https://github.com/earendil-works/pi/issues/5959)).
+- Fixed inherited OpenAI-compatible streaming to preserve encrypted `reasoning_details` that arrive before matching tool call deltas ([#5114](https://github.com/earendil-works/pi/issues/5114)).
 - Fixed broken TUI documentation links to the plan-mode extension example ([#5957](https://github.com/earendil-works/pi/issues/5957)).
 - Fixed transient extension UI and session-start messages emitted during session replacement or reload so they remain visible, and kept reload input blocked until reload completes ([#5943](https://github.com/earendil-works/pi/issues/5943)).
 - Fixed the plan-mode example to preserve active custom tools, skip the action prompt when no plan is found, and queue refinement/execution follow-ups correctly from `agent_end` ([#5940](https://github.com/earendil-works/pi/issues/5940)).
 - Fixed `pi update` to install the exact version returned by the Pi update check, make `--force` reinstall that checked version, fail instead of falling back to an unversioned reinstall when no version is available, and report both the old and updated versions.
+- Fixed update notifications to display the actual changelog URL as the hyperlink text.
