We are delighted to announce the immediate availability of NovaMind 5.2 for Mac. This release brings a wide range of behind the scenes improvements, and some user-visible changes.
The biggest single change is the complete replacement of the data layer of the application with a new one that is designed to be faster, more stable, and easier to maintain. During the course of the development of the new data layer, we have been encouraged to find out how easy it was to track down and correct issues, in comparison to the old framework, where we were often unable to reproduce issues, which made them very difficult to fix.
You can get the new version either by clicking the Download button on the NovaMind web site, or if you already have NovaMind 5 installed, it will automatically be found by the update system. This update is currently only available for NovaMind 5 when running on MacOS X 10.6 and 10.7
Although there are hundreds of improvements throughout the application, here are some of the main new features, improvements, and bug fixes:
- Concurrent document opening on OSX 10.6 and 10.7 – this means that NovaMind can be opening multiple documents at the same time, and present them to you as they each become available, without holding you up from working.
- Native autosave system – we can now work with the system native autosave system without having to use the one we wrote, right back to OSX 10.5. This means that when you drag a file from the title bar, it will be the one you expect, instead of the one we had to hide away in a working folder, and all the operating system level operations for automatically opening autosaved files etc work as they would for other applications.
- Dynamic autosave delay in OSX 10.7, so that the autosave adjusts to how long it took last time automatically.
- Asynchronous file writing in OSX 10.7 – this means that when either you save a file or the autosave system saves a file, it will return control to you as soon as physically possible (in most cases instantaneously), while the program goes on and saves the file in the background.
- Significantly improved error reporting – this means that we are much more likely to be able to find and fix a problem from the very first report.
- Improved performance on the updates of the inspectors.
- Improved performance for all editing operations.
- Improved handling of undo and redo.
- Additional tweaks to work more nicely with some of the new features of Mac OS X 10.7 Lion.
