The new Release 20.03 is out! You can download binaries for Windows and many major Linux distros here .
Do you have the SmartIndent plugins installed and enabled?
Where can I plug Smartident? I installed codeblocks-contrib taken from "deb http://apt.jenslody.de/testing testing main". I write in C. In the list of plugins Smartiden not.
sudo dpkg-reconfigure codeblocks-contrib
