Werner posted about this new release at the tail end of another thread, but I think that's too hidden and that it rates it's own thread.
[ Cross posted from the Google Discuss Group:
Be advised that a new version - version 1.4 - of TTFA was released a few days ago.
This is substantial upgrade:
Version 1.4 (2015-Oct-04)
-------------------------
* Support for Thai and Lao scripts.
* Support for the Arabic script.
* Better support for scripts that contain superscript-like and
subscript-like glyphs, e.g., the International Phonetic Alphabet (IPA).
* Accents and other `non-base' glyphs are now hinted without snapping to
blue zones.
* A new control instruction syntax form was added to adjust the mapping
between glyphs and styles. Right now, its usage is quite limited; a
forthcoming version will give much more flexibility.
* The `touch` keyword in a delta instructions file was buggy: If used for a
point `P` at a ppem value `s`, it sometimes led to unwanted movements
of `P` for ppem values unequal to `s`, thus causing outline distortions.

Note that the last bulleted item above is a rather nasty bug that got fixed and is documented in this previous thread on Typedrawers:
So if you use TTFA, downloading this version seems de rigeur.
Also, if you want to learn more about using TTFA, the Typedrawers thread begins with a link to a demonstration video showing how TTFA is used by designer Jasper de Waard. It was created by Jasper at Dave Crossland's request and it's very informative:
Much gratitude to TTFA's main developer Werner Lemberg.
And thanks also to Mike Duggan and Greg Hitchcock of Microsoft, as well as knowlegeable designers like David Berlow, who have all contributed their thoughts and ideas to make TTFA a better tool for all.
