The important part right now is that we get on top with fixing them. For 5.18 there was /waaaay/ too much feature pushing for this release. Even if the new stuff itself doesn't introduce breakages, it takes developer and review time away from what should be a month of being totally on top of bugzilla.
It's better to have a minor bug that you know, than uncertainty of new code. I don't know if it's because of the LTS or because of proximity to Christmas. Our next LTS should be better as we'll be doing any big work on Plasma6 during the prep time. It can have a 4 month feature freeze. I'm also seeing a rising amount of pushing without review on the core repos. I would like for us all to (nicely) call that out if we see any instances. Reviews are super important, the best time to fix a bug is before it even happens. Even for small commits and "safe" commits. -- Other positive steps, can everyone please go to bugzilla -> preferences -> saved searches and add "Plasma5-All-Critical" to their footer. Saved searches are a good thing to make use of, so please share any other useful ones, and help keep these ones up to date with changing plasma products. David
