To compensate this delay we have even upgraded the IDE to the most recent 4.1.0 QtCreator. **Based on QtCreator 4.1.0** We have based the new IDE on the most recent QtCreator upstream release, which brings a lot of new features and fixes. To see whats new there just check out [here](http://blog.qt.io/blog/2016/08/25/qt-creator-4-1-0-released/). **LXD based backend** The click chroot based builders are now deprecated. LXD allows us to download and use pre built SDK images instead of having to bootstrap them every time a new build target is created. These LXD containers are used to run the applications from the IDE. Which means that the host machine of the SDK IDE does not need any runtime dependencies. **Get started** It is good to know that all existing schroot based builders will not be used by the IDE anymore. The click chroots will remain on the host but will be decoupled from the Ubuntu SDK IDE. If they are not required otherwise just remove them using the Ubuntu dialog in Tools->Options. If the beta IDE was used already make sure to recreate all containers, there were some bugs in the images that we do not fix automatically. To get the new IDE use: ``` sudo add-apt-repository ppa:ubuntu-sdk-team/ppa ``` ``` sudo apt update && sudo apt install ubuntu-sdk-ide ``` Check our first blog post about the LXD based IDE for more detailed instructions [here](https://developer.ubuntu.com/en/blog/2016/06/14/calling-testers-new-ubuntu-sdk-ide-post/).
