We have sunsetted support for our kubernetes and helm chart managed self-hosted offering. This means we no longer offer support for fixing to specific versions of PostHog. A docker image is pushed for each commit to master. Each of those versions is immediately deployed to PostHog cloud.
The deploy-hobby script allows you to set a POSTHOG_APP_TAG
environment variable and fix your docker-compose deployed version of PostHog. Or you can edit your docker-compose file to replace each instance of image: posthog/posthog:$POSTHOG_APP_TAG
with a specific tag e.g. image: posthog/posthog:9c68581779c78489cfe737cfa965b73f7fc5503c
Changes to PostHog are listed in our changelog, and in GitHub.
