Steps required are:
* Bump release version (in cmake and spec files). git commit -m "Release of x.x.x"
* Merge to master
* Create signed release tag: git tag -u $EMAIL -s vx.x.x -m "Release of x.x.x"
* Upload release tarball: ftp://upload.kde.org/README
* Create sysadmin tickets to move release tarballs to the desired location (include sha256)
* Blog about release
* Announce release on kde-apps-announce and pim mailinglist
We will need to release:
* (kasync)
* (kimap2)
* (kdav2)
* sink
* kube

Tarballs are created and uploaded like this (sha256 for sysadmins):
```
$ git archive --format=tar.xz --prefix=kasync-0.1.0/ v0.1.0 > kasync-0.1.0.tar.xz
$ sha256sum kasync-0.1.0.tar.xz
7cc451662fcf5c2f67cbebdeb03020 kasync-0.1.0.tar.xz
$ curl -T kasync-0.1.0.tar.xz ftp://upload.kde.org/incoming/
```
