If anything, the CB user community would be far better served by following the TortoiseSVN release management structure.
Why? Who cares if a new nightly suddenly has some bugs? It is trivially easy to go back to an older version.
TortoiseSVN is a totally different topic. For a start TortoiseSVN is rather "hard" to install. It inserts itself deeply into the system and even requires a reboot. If anything goes wrong here, that could be rather fatal.
But Code::Blocks? Okay, maybe some function will fail. That is hardly a drama. Going back to an older version takes at most two minutes (less, if you keep the older version installed in parallel).
And the chance for a data-loss or any other kind of damage is rather minimal too. Please note, that the embedded text-editor is a separate project, which AFAIK is going through a more ridigd release procedure. Adding to this any sane developer will use some kind of version control system, so even in the rather unlikely event, that some files are damaged, the damage would be limited to the work since the last commit.
Sorry, but worrying about the risk and the consequences of a malefunctioning nightly is extremly irrational in my opinion.
I would prefer it if the regular releases would be completely abolished. There are a waste of developer time IMHO.
