I actually want to wait until 2.6.0 - it's almost out: https://github.com/vuejs/vue/projects/4
The main reason for waiting for 2.6.0 and not upgrading to 2.5.22 now is that I don't really want to do regression testing twice, as version upgrade is a rather major change.
The main reason for 2.6.0 instead of 2.5.22 is that it will improve TimeSpan integration in template, allowing to omit .toString() calls: vuejs/vue#8093

Feel free to remove the branch

If this is the approach, what are you going to do when 2.6.1 comes out?

Depends on what it brings to the table; we will skip it if we won't benefit from the update. If it does have something useful, then it depends; if it has some critical stuff - we will update to 2.6.1 right away; if it has only minor improvements, we will check what will be in 2.6.2 - if nothing, we will update to 2.6.1 right away, otherwise wait for 2.6.2.

2.6.1 is going to be a buxfix release. If you at, for example, 2.5.18 (which had some features), everything after that (really, including 2.5.22) was bugfixes. Some of the most common bugs that vue tends to have, given the release history, are memory leaks. Not something that we have been trying to catch.

2.6 is going to inherit all of 2.5.22's features and fixes. So, in all likelihood, any regressions from switching to 2.5.22 will show up in 2.6.0.

I am not even sure what you mean by regression testing. It's not like we have a separate GUI test process. People just point out glitches as they see them.
