 Starting with Sentry `21.8.0`, if you need to have Sentry access services which do not have TLS certificates from publicly trusted CA roots, it's now possible to easily add them to the containers. Just add the certificates to the `certificates` folder inside the root of your Sentry install and restart the containers. Your custom CA roots will be used in addition to the publicly trusted CA roots.

 Sentry can use [MaxMind's free `GeoLite2-City` database](https://dev.maxmind.com/geoip/geoip2/geolite2/) to geolocate IP addresses, providing additional context for error events where the end user's IP address is known and for the session history of users logging into your Sentry installation. We bundle MaxMind's [`geoipupdate`](https://hub.docker.com/r/maxmindinc/geoipupdate) tool for this purpose.

 Sentry cuts regular releases for self-hosting to keep it as close to [sentry.io](https://sentry.io) as possible. We decided to follow a monthly release schedule using the [CalVer](https://calver.org/#scheme) versioning scheme, with a primary release on the [15th of each month](https://github.com/getsentry/self-hosted/blob/704e4c3b5b7360080f79bcfbe26583e5a95ae675/.github/workflows/release.yml#L20-L24). We don't patch old versions, but if a bug is bad enough we may cut an out-of-cycle point release, which, like our regular monthly releases, is a snapshot of the latest versions of all of our components. You can find the [latest release](https://github.com/getsentry/self-hosted/releases/latest) over at the [releases section of our self-hosted repository](https://github.com/getsentry/self-hosted/releases/).
