I did some tests with epub in 3.3.0 and 3.5.0 (
https://wiki.mobileread.com/wiki/EPub_Reader_Test), I noticed:
- Even with 3.3.0, I didn't see the long paragraph bug in the sample text. Maybe I'd need longer paragraphs, but as noted that was enough to trigger the bug in the Orizon.
- Auto margins work! It should now be possible to center blocks of text or tables.
- The bug with low-bitdepth PNGs seems fixed!
- Missing characters do not show as a question mark or rectangle, instead they show blank or as some other character, which may be more confusing.
- Left-to-right text works! At least in Hebrew, Arabic ligatures are probably more demanding.
