After 5 months we are releasing a new version of plasma-nm for KDE 4.x containing a lot of bugfixes, minor design improvements and internal changes (see my previous blog post). This is probably last major release since we are now focused to KF5/Plasma 5 version, but we will be still backporting all fixes and you can expect at least one more bugfix release in future.
You can get a tarball from usual location, compile it from git or wait for an update in your distribution.
Also if you want to discuss things related to plasma-nm personally, suggest new ideas, complain about it, or just buy me or to anyone from our small plasma-nm team a beer you will have an opportunity, because

it failed to build here,buld log is at[1]

Hmm, that’s weird. I updated it yesterday for Fedora and everything was compiled without an error. In what distribution you are trying to compile it? Do you have installed development libraries for Qt?
i tried to build on pclinuxos.
The build process continued after i included QTextStream header so the problem was a missing header.
See https://bugs.kde.org/show_bug.cgi?id=338124. Once I find the problem I’ll create a new tarball.
I am using nm with the plasma 5 supplied by opensuse. Initially it worked well, but now it makes the plasmashell crash systematically. Any idea what I can do about it? Should I compile your latest version (not that I dream about doing that)?
The best thing you can do is to report a bug in KDE Bugzilla and attach a backtrace from your crash, otherwise there is no chance how I could find identify your problem.
that’s probably beyond my capabilities … maybe I better revert to kde4 then.
actually, finding the backtrace was easier than I thought. Shall I send that to you by direct mail – or post here?
Would be better to fill a bug here [1], so we can track it and keep it for other people having the same problem. Just select your version, platform and so on and attach there your backtrace. Also if you could install debug symbols for plasma-nm and libnm-qt libraries and provide a backtrace with installed debug symbols that would be perfect.

will do. Interestingly, I don’t seem to have libnm-qt in any repository. Does that already indicate something?
You have it installed, because it’s a hard dependency for plasma-nm. It’s probably called networkmanager-qt or something like that, just check dependencies for plasma-nm.
although it did tell me this:
loading repository data…
Reading installed packages…
No provider of ‘debuginfo(build-id) = d3ca8665813dd850a9dc3d83639d23b9dd099cf2’ found.
Resolving package dependencies…
The following 9 NEW packages are going to be installed:
libKF5Declarative5-debuginfo libKF5ModemManagerQt5-debuginfo libQt5Core5-debuginfo libQt5Gui5-debuginfo libQt5Widgets5-debuginfo
libQtQuick5-debuginfo plasma5-workspace-debuginfo plasma-framework-private-debuginfo plasma-nm5-debuginfo
9 new packages to install.
so maybe that will do it
