Important

feat(environment-variables): Removed Is Build variable? option from everywhere.
This means that all environment variables are available by default during buildtime and runtime.
But in the same time, we introduced a Buildtime Only? feature, which will let you set an env variable to available ONLY during buildtime - it is useful for special secrets, like npm auth tokens that are only required durind buildtime, etc.

Others

feat(ui): Show current version in changelog view, so you will know which releases you should check.
feat(core): All ssh commands will use retry mechanism to prevent one-time network/other related issues.
feat(pull request): By default, only repository (or organization) collaborators or people with higher privileges could auto-deploy pull requests. You can allow anyone to be able to do this in the Advanced settings (if you have pull requests enabled).
fix(ui): Wrong link in email settings page.
fix(api): Regenerate labels if domain changed through the API.
fix(changelogs): Instances fetch Github Releases from our custom CDN to prevent Github rate limit.
