GET /releases/branches.php serves stale/inconsistent latest from CDN edge cache #2007
Closed as not planned
Description
Affected Page URL
https://www.php.net/releases/branches.php
Describe the bug
Since around the 8.5.10 release, repeated requests for this endpoint intermittently return "latest": "8.5.9" or "latest": "8.5.10" for the 8.5 branch.
Steps to reproduce
Some package managers rely on this for latest release detection, as evidenced by version checks and upgrades flapping between two versions.

- https://github.com/ScoopInstaller/Versions/commits/master/bucket/php84.json
- https://github.com/ScoopInstaller/Versions/commits/master/bucket/php85.json
Expected behavior
/releases/branches.php should be effectively up-to-date and consistent for consumers. Ideally the CDN purges /releases/branches.php whenever release data is deployed.

As the cache expired or the CDN cache was purged, this issue no longer occurred. Hope this API endpoint is more reliable.

It seems to have happened again. Any updates on investigating what went wrong?

Did I miss something? Is there any specific reason the CDN cache for this API is set to expire in 30 days and is not purged?
