14 DAY TRIAL // Here's another Christmas present for all fans of the Open Source ecosystem, as Calibre developer Kovid Goyal announced the availability of Calibre 2.75.1 maintenance update on Christmas Day.
The fact of the matter is that Calibre 2.75.0 arrived two days before Christmas Day, but the small 2.75.1 bugfix release landed a couple of days later, on December 25, 2016, to address a regression in version 2.75.0 that broke the Live CSS feature in the editor, which might have also caused various other minor issues in the viewer.
However, the biggest new feature of the Calibre 2.75.x release is support for new 4.2 firmware version for Kobo e-book readers, along with the ability to use the amazon_com, amazon_au, and amazon_in identifiers in the Book details panel. Of course, lots of bugs reported by users since Calibre 2.74.0 have been resolved.
Improved news sources, bug fixes
The Ambito Financiero, Irish Times, Guardian, Independent, Ambito.com, and Die Zeit (subscription) news sources have been updated as well in Calibre 2.75, and among the bugs fixed, we can mention an issue with the Kobo driver that would have sent incorrectly sized covers to some Kobo e-book readers.
The Edit Book component appears to have received the most attention in this new maintenance update of Calibre, and the developer patched a bug that wouldn't allow newlines to be matched by the "Search ignoring markup" tool, and made the "Customize Template" window to be freely resizable.
Also for the Edit Book component, the Search panel and "Spell Check" dialog can now be made much narrower than before, and the "Search ignoring markup tool" will now correctly ignore comments and processing instructions. Other than that, there's a patch for the "is" and "is not" rules to match currentColor in the CSS Transforms component.
The E-book Viewer component has been updated as well, and it looks like JavaScript code in a book won't be able to access files on the host computer using the XMLHttpRequest API, and the swipe-up gesture was made to allow users to move to next section instead of previous one.
Last but not least, the EPUB Input feature can now correctly handle HTML files that are located in a folder above the OPF file. You can download Calibre 2.75.1 for GNU/Linux, macOS, and Microsoft Windows operating systems right now from our website. Check out the full changelog attached below for more details on the changes.
