So in order to understand what went wrong it is best not to update.
Absolutely no. There are some many great features coming which you are missing just because of that dummy message!
I see the green successful compilation message also in Lazarus trunk. Be assured that it was not removed. There's probably some option buried between the many settings which turns this line off.
Find out where your user profile is stored: "View" > "IDE Internals" > "Global IDE options" - the line "Primary config directory" tells you the corresponding folder. Then make a backup copy of this folder, just in case something goes wrong with the next tests. Always exit Lazarus before each test. At first rename the entire folder so that the IDE does not find it any more. The next time you start Lazarus the profile will be recreated with default parameters. Recompile some simple project (all your installed components will not be found now) and see if the green line appears. If not - I am wrong and the error is somewhere else. But if yes you know that the bug is somewhere in the profile.
Now you have two options: either keep the new profile, install all your components again and restore your settings. Or do the same trick with the inidividual files in the folder - i.e. rename one file by one to have the IDE replace it by a default file and see whether the green line is back. If it does not delete the newly created file and restore the old one, then proceed with the next file.
