Just curious, as a move to v5 will likely end up needing some regression testing on all of our projects. Were there any bug fixes between v4 and v5 that would make the move more likely to be beneficial?

Hi Jonathan,
We talk about the major changes we implemented into Automise 5 in our blog post about the release.
[https://www.finalbuilder.com/resources/blogs/postid/744/automise-5-released](https://www.finalbuilder.com/resources/blogs/postid/744/automise-5-released)
The highlights of this are:
- New stepping engine. Meaning faster builds.
- Action list dependencies. Meaning you can link action lists together, and force their run as prerequisite.
- Break point conditions for debugging.
- New project formats. Makes merging changes to projects easier.
- New actions. Amazon S3 and Azure.
In addition to this we will only be adding new features and actions to Automise 5. Automise 4 & 5 will both get bug fixes, but that will only last for another year for Automise 5.
