+          - Updates \`${CHANGELOG_FILE}\` with a new section since the last tag
+          - Updates \`${README}\` version header
+
+          Note: \`composer.json\` is intentionally untouched. Packagist reads the version from the git tag, and there is no \`version\` field in \`composer.json\` to bump.
+
+          ### After merging
+          1. Push tag \`${TAG}\` from the merge commit on \`master\` to trigger the publish workflow:
+             \`\`\`
+             git checkout master && git pull
+             git tag ${TAG}
+             git push origin ${TAG}
+             \`\`\`
+          2. The publish workflow validates the tag and creates a draft GitHub release. Packagist auto-syncs from its GitHub webhook on tag push, so there is no upload step.
+          3. Review the draft GitHub release and click **Publish release** to make it live.

+## [2.5](https://github.com/mixpanel/mixpanel-php/tree/2.5)

+- `timeout` option now refers to `CURLOPT_TIMEOUT` instead of `CURLOPT_CONNECTTIMEOUT` in non-forked cURL calls, it has been removed from the SocketConsumer in favor of a new `connect_timeout` option.
+- Added a new `connect_timeout` option for CURLOPT_CONNECTTIMEOUT in non-forked cURL calls (CurlConsumer) and the socket timeout (SocketConsumer)
+- Set default timeout (CURLOPT_TIMEOUT) to 30 seconds in non-forked cURL calls

+## [2.0](https://github.com/mixpanel/mixpanel-php/tree/2.0)
+
+- Changed the default consumer to be 'curl' (CurlConsumer)
+- Changed the default setting of 'fork' to false in the Curl Consumer. This means that by default, events and profile updates are sent synchronously using the PHP cURL lib when using the Curl Consumer.
+- 'createAlias' uses the CurlConsumer with 'fork' explicitly set to false (as we need this to be synchronous) instead of the SocketConsumer.
+- Fixed bug where max_queue_size was never read
