Significant change to invisible font system
...
to improve correctness and compatibility with
external programs, particularly ghostscript.
We will start mapping everything to a single glyph,
rather than allowing characters to run off the end
of the font.
A more detailed design discussion is embedded into
pdfrenderer.cpp comments. The font, source code
that produces the font, and the design comments
were contributed by Ken Sharp from Artifex Software.

Font and classifier output structure cleanup.
...
Font recognition was poor, due to forcing a 1st and 2nd choice at
a character level, when the total score for the correct font is often
correct at the word level, so allowed the propagation of a full set
of fonts and scores to the word recognizer, which can now decide word
level fonts using the scores instead of simple votes.
Change precipitated a cleanup of output data structures for classifier
results, eliminating ScoredClass and INT_RESULT_STRUCT, with a few
extra elements going in UnicharRating, and using that wherever possible.
That added the extra complexity of 1-rating due to a flip between 0 is
good and 0 is bad for the internal classifier scores before they are
converted to rating and certainty.

Major change to improve layout analysis for heavily diacritic languages:
...
Tha, Vie, Kan, Tel etc.
There is a new overlap detector that detects when diacritics
cause a big increase in textline overlap. In such cases, diacritics from
overlap regions are kept separate from layout analysis completely, allowing
textline formation to happen without them. The diacritics are then assigned
to 0, 1 or 2 close words at the end of layout analysis, using and modifying
an old noise detection data path.
The stored diacritics are used or not during recognition according to the
character classifier's liking for them.
