A big thanks to @ezdiy and @benoit-pierre for taking on the major effort of updating MuPDF (https://github.com/koreader/koreader/pull/11940). Unfortunately or hopefully you won't notice a thing, but some edge cases in PDF rendering have been fixed.

Likewise our gratitude to @Commodore64user for the many non-touch/keyboard focused improvements.

If you used the built-in update to try out a development version in the last week of June you might need to overwrite the install manually, see https://github.com/koreader/koreader/issues/12115.

This month's logo was contributed by @Sonnenfee
