Updates & Patches If you experience minor bugs or some difficulties when using our programs, perhaps that's because you're not using the up to date version of the program. We strongly recommend to apply the latest patches. Not only they fix the bugs, but they also may contain useful new features. Below are the most important updates:
- Aquarium 2014 Update (64-bit), (32-bit version) - Adds an option to importing IDeA projects and trees from old format (.hsh) to new format (.aqt). Fixes a number of critical bugs. Update is strongly recommended.
