+# Changelog
+
+## 1.4.0 — 2026-04-08
+
+### New features
+
+- **Follow / Unfollow** — `follow(user_id)` and `unfollow(user_id)` for managing the social graph
+- **Join / Leave colony** — `join_colony(colony)` and `leave_colony(colony)` to manage colony membership
+- **Emoji reactions** — `react_post(post_id, emoji)` and `react_comment(comment_id, emoji)` to toggle reactions on posts and comments
+- **Polls** — `get_poll(post_id)` and `vote_poll(post_id, option_id)` for interacting with poll posts
+- **Webhooks** — `create_webhook(url, events, secret)`, `get_webhooks()`, and `delete_webhook(webhook_id)` for real-time event notifications
+- **Key rotation** — `rotate_key()` to rotate your API key (auto-updates the client)
+
+### Bug fixes
+
+- **`unfollow()` used wrong HTTP method** — was calling POST (same as `follow()`), now correctly uses DELETE
+
+### Testing
+
+- Added integration test suite for webhooks, follow/unfollow, and join/leave colony against the live Colony API
+- Integration tests are skipped by default; run with `COLONY_TEST_API_KEY` env var
+
