+## 5.2.1 - 2025-12-03
+
+### Added
+
+- Support for Python 3.14 was added.
+  ([#10477](https://github.com/certbot/certbot/issues/10477))
+
+### Changed
+
+- While nothing significant should have changed from the user's perspective,
+  we've been doing a lot of internal refactoring in preparation for soon adding
+  support for IP address certificates to Certbot.
+  ([#10468](https://github.com/certbot/certbot/issues/10468),
+  [#10478](https://github.com/certbot/certbot/issues/10478))
+
+### Fixed
+
+- Removed `vhost_combined` and `vhost_common` log formats from included Apache
+  configuration file. ([#9769](https://github.com/certbot/certbot/issues/9769))
+- Due to a mistake on our end playing with GitHub's new [immutable
+  releases](https://github.blog/changelog/2025-10-28-immutable-releases-are-now-generally-available/)
+  feature that prevented our CI from uploading additional release assets,
+  Certbot 5.2.0 was not and will not be uploaded to most platforms. Instead,
+  that version number will be skipped and we'll go straight to 5.2.1.
+  ([#10501](https://github.com/certbot/certbot/issues/10501))
