If you have installed package, newer than available in repo, you can use sudo pacman -Syuu(here must be to “uu”, it is not mistake),which downgrade your packages.Gotten from https://bbs.archlinux.org/viewtopic.php?id=128502.
That is true but you should really investigate why that is the case before downgrading.
In many cases, you should be switching to a more up to date mirror instead of downgrading.
In other cases, it may be deliberate or OK.
I am not sure why? If I just want to have more stable release, why downgrading not good here?
Also seems I have seen regression: in this week I twice have problems with sound: first was when pc does not play any sound before I didn’t restart it. Second was yesterday, when clicking in the sound widget in the KDE Plasma panel played sound in the connected Bluetooth-Headset, but when I closed widget and just scrolled to sound icon in the panel, sound played in the pc dynamics,not in the headset.
Had you been installing “stuff” from the Testing repo?
If not, sync your local data base to more up to date servers.
And run sudo pacman -syu
You’ll be on Stable.
I had Arch updates, today I changed all hooks again to EndeavourOS
Also, can I ask you: Arch uses have Plasma 6.7, but in EndeavourOs I didn`t have it. EOS receive update later?
EOS uses Arch’s repo as is plus its small own repo.
99.99x % of things you install in your EOS systems comes to you from ARCH.
So keep your system updated and rolling. You’ll get the “Latest && Greatest” !
Don’t you be worried!
Arch users don’t have Plasma 6.7. Just take a look, It’s only in testing repo. So if you want it, just take Plasma 6.7 from testing repo
Just checked on my Arch install no Plasma 6.7
Operating System: Arch Linux
KDE Plasma Version: 6.6.5
KDE Frameworks Version: 6.27.0
Qt Version: 6.11.1
Kernel Version: 7.0.12-arch1-1 (64-bit)
Graphics Platform: Wayland
Processors: 12 × AMD Ryzen 5 7600 6-Core Processor
Memory: 16 GiB of RAM (14.7 GiB usable)
Graphics Processor: AMD Ryzen 5 7600 6-Core Processor
It hasn’t been released yet though. It’s still in testing.
Yes I know that because I also checked the packages list on the Arch website but there is a certain user that seems to be a bit confused , that’s why i posted it. 
Fedora user said that he had plasma 6-7.
So in real Fedora with bleeding edge, not Arch?
Arch is rolling, that doesn’t necessarily mean bleeding edge all the time.
From that I read in the net , Ubuntu is for typical users, Debian is for user, wh o needs have very-very stable OS, which use LTS.Fedora for users,who want try new, Arch for users, who want have new mpre than have stable linux, with bleeding edge.
I know, rolling and blleding edge mean different.
But in my PC EndeavourOS work without bugs,when in Fedora I had them many.
This was copied from the Fedora forum https://discussion.fedoraproject.org/t/kde-plasma-6-7-0-is-out/193936
The reality is pushing the update to stable is just one part of the process for making it installable via a dnf update. Depending on lots of factors, it can take a day (or even more) for individual mirrors to make the update available for installation. If you absolutely, positively, need the update yesterday, pull it from the koji builds, or build it yourself.
So the user you are talking about might have used one of the two methods mentioned on the last line to get the update.
From what I can tell, Fedora’s developement team updates Plasma much more regularly because once KDE releases a new version of Plasma, that’s the only version supported and often it doesn’t line up at all with a Fedora’s point release schedule. Plus, KDE IIRC pretty much said LTS releases that ship Plasma kind of don’t make sense due how to they operate regarding things like bugs and security vulnerabilities. Fedora KDE works more similarly to a semi-rolling release distro, where the desktop can change mid-way through the 6 months between Fedora releases, but important system packages and libraries don’t get updated with new features until the new point release.
Bleeding edge doesn’t mean you get the new packages with no testing. There is at least some basic testing done to check for issues, but it isn’t as riguros as stable releases or LTS releases.
Sometimes Fedora releases it first, other times it’s Arch.
Can confirm that Fedora is on Plasma 6.7
