>log in to commentHey everyone, wanted to share some cool updates for Happy Changelog pipelines for GitHub and GitLab! I figured some of you might benefit from them. I've added the ability to use customizable templates for your changelog version titles, giving you more control over the look. There's a new option for injecting custom scripts before new changelog is committed! This will help you automate other file changes after a version is created - update README, other version files, or whatever you need. Both workflows already use this for readme updates if you need a place to copy from. Plus, I enhanced the integration with the Changelog Browser. You can now provide a custom URL for your Changelog Browser and control exactly how the links are generated, choosing between the default branch (which is now the new default!), a specific commit, or a version tag. I realize it's not that useful for SaaS GitLab where public files are CORS-ed, but I'll work on that as well on Changelog Browser Side at some point.
