Main novelties of Caliber 6
This new version of Caliber 6 that is presented, most of its changes, are features that were introduced during the development of the 5x branch and of the most notable is the “Full Text Search”, in which caliber can optionally index the full text of the books in the library to allow instant word searches within any book.
It is mentioned that to use this functionality, just click on the FT button on the left edge of the search bar. Once indexing is complete, all text in the entire library can be searched. When you add new books to the library, they will be automatically indexed in the background.
Another of the changes that stands out in this new version are the new CPU architectures which has added support for the Apple Silicon CPU architecture on macOS and the ARM CPU architecture on Linux.
In addition, has removed support for 32-bit CPUs because Qt (one of its dependencies) has removed 32-bit CPUs. In particular, on Windows, the caliber installer will now automatically uninstall 32-bit caliber and replace it with 64-bit caliber, plus it's also worth mentioning that support for Windows 8 was dropped in this new release.
On the other hand, the new feature of read aloud in the ebook viewer. In order to access it, simply click the "Read Aloud" button in the viewer controls to start reading the text of the book aloud from the current page. This works through the operating systems' text-to-speech engines.
Regarding incompatibilities What's in this new version:
- Because caliber has now moved to Qt 6, some third-party plugins will no longer work, until they are also ported to Qt 6.
- If caliber 5 and caliber 6 are used in the same library, books added with caliber 5 will not be automatically indexed for full-text search, so the index will need to be rebuilt periodically.
