Open-source software evolves with the constant feedback of users. New improvements often come with new bugs, bug reports and then bug fixes. This mechanism works only if most users keep on updating regularly the software.
With Brainstorm, we're trying to provide fast solutions to new problems that users report. If you follow our debugging guidelines, you would get a fix for the bugs you reported within a few days, and the entire community of users would benefit from it.
If you'd like to contribute to the constant improvement of tools: please help us with the debugging.
If you don't, rather than using outdated versions of Brainstorm, you might be interested in using other tools, probably commercial solutions that would include less options and no updates, but less bugs.
This is free open-source software, you are free to use it the way you want, but note that we can't provide any help through the forum for versions of Brainstorm that are not up-to-date. Unfortunately we don't have the necessary resource to maintain multiple versions simultaneously. There are no "stable" releases of Brainstorm.
