In the past couple months I've been busy porting KDE Telepathy project over to Qt5 and KDE Frameworks 5. I'm happy to announce that the ports have been completed and after about a month of testing, KDE Telepathy was moved to join the KDE Application releases with the nearest release being the 15.04 one. This should ensure more regular releases with new version every 4 months.
KDE Telepathy stayed moreless the same in the UIs, but lots of things have changed under the hood. First of all KDE Telepathy will now adopt the KDE Applications versioning scheme, meaning that the next release and first Qt5/KF5 based will be version 15.04. There's only little sense in maintaining different internal versions, that just makes things unnecessarily complicated.
Very important change is the switch to an account management infrastructure based on the Accounts SSO project, which is used eg. in Ubuntu's Unity (as well as on the Ubuntu Phone) and in a form also in Gnome or ElementaryOS. The KDE's project integrating Accounts SSO carries the name KAccounts and is now the new way to set up and configure your KDE Telepathy accounts. This will be part of KDE Applications 15.04 release.
KAccounts does have a simple migration of your current KDE Telepathy accounts into KAccounts, it just cannot migrate your passwords, therefore when you first try to connect, you will get prompts for passwords to your accounts, just put them in and tick "Save password" and your password will now be stored with KAccounts. If you're not already using some daily builds of KDE Telepathy with KAccounts, I'd advise to wait with upgrading till beta 2 as I'm working on couple improvements to the migration step.
Next big~ish change is within the metacontacts/contact aggregation framework KPeople. It used to depend on kdepimlibs but after revising some things, the dependency was dropped and KPeople is now fully self-contained framework, transitively meaning no more kdepimlibs dependency for KDE Telepathy.
Both of these transitions were quite complex and so there might be bugs. Please take the opportunity of KDE Applications 15.04 betas and test if everything works to your standards and please report any bugs you encounter at bugs.kde.org product Telepathy or KAccounts or KPeople, so that we may fix them before the final release.
The 15.04 release unfortunately will not feature the calling component of KDE Telepathy, the Call UI. The team is simply undermanned and nobody particularly understands the whole Telepathy calling stack. Therefore it's now left out of releases until it finds a new maintainer who can take care of it and bring it to the standards of the rest of KDE Telepathy suite.
There will be one more KDE Telepathy 0.9 (kdelibs4 based) release, featuring updated translations and couple improvements to the Call UI, after that only critical security fixes will be released for the 0.9 line and all focus will go to the Qt5/KF5 versions.
