As this is the first blog post in 2020, first of all: Happy New Year to all of you! 🥳

This fourth RC of 1.4.0 fixes some regressions and issues in the new functionality observed with the prior RCs:

You can find the full changelog and release notes as usual on Github.

Special thanks to everyone who contributed to this release candidate and provided full, analyzable bug reports, and also @CapnBry and @fieldOfView for their fixes!

As the past RCs have shown me that a lot of people appear to be unaware of this: Please do not install this RC if you expect a fully stable version. It is not a stable release, it is a release candidate, and of the next big release to boot: severe bugs may occur, and they might be bad enough that they make a manual downgrade to an earlier version necessary - maybe even from the command line.

You should feel comfortable with and capable of possibly having to do this before installing an RC.

If you want to and can help test this release candidate, you can find information on how to switch to the “Maintenance RCs” release channel in this guide if not already done (also linked below). This is the first RC of the 1.4.0 series that is also available on the “Maintenance RCs” channel, the prior RCs were only pushed to the “Devel RCs” release channel. If you are tracking “Devel RCs” you will also get an update notification for this, since “Devel RCs” also tracks releases on the “Maintenance RCs” and “Stable” channels, so no need to switch.

Please provide feedback on this RC. For general feedback you can use this ticket on the tracker. The information that everything works fine for you is also valuable feedback 😄. For bug reports please follow “How to file a bug report” - I need logs and reproduction steps to fix issues, not just the information that something doesn’t work so make sure to fill out all fields of the issue template.


Depending on the feedback regarding this version I’ll look into fixing any observed regressions and bugs and pushing out a follow-up version as soon as possible and necessary.
