Much improved Kobo support
calibre can now natively edit, view and convert KEPUB format files used by the Kobo. It also automatically converts EPUB to KEPUB when sending books to Kobo devices (can be configured by right clicking the kobo icon in calibre).
Connect to folder: Allow connecting a specific device
calibre can now connect to a folder and treat it as though it is a USBMS based device. This is useful particularly on Chromebooks where USB devices appear as folders rather than actual devices.

ToC editor: Allow moving of multiple selected items in the Table of Contents
macOS: The calibre application icons in the dock are now displayed in a white frame to follow Apple's current recommended icon style
Kobo driver: Add support for new firmware on Tolino devices
Book details: Add option in to suppress author search links

Fix a regression that broke tabbing to edit cells in the book list when some columns have been hidden or re-ordered
Catalog generation: Allow using templates that access the database for notes
Fix a bug when renaming authors to a name with commas in it
Full text search: Also index text in ZIP and RAR archives as these can be viewed by the calibre viewer
E-book viewer: Fix Table of Contents current entry tracking not working for some books
When reading metadata from HTML also recognize name="subject" meta tags as calibre tags
E-book viewer: Fix viewer not closing on the interrupt signal
Edit book: Download external resources: Fix incorrect filename if the server returns a generic Content-Type header
Metadata download: Publisher/series transform rules: Fix values with commas in them not working
