Amazon has released a firmware update for its current generation Kindle. It brings it to version 4.10 and among the important features is a new font.
Personally the font does seem to be a bit crisper than it was previously, but some may not see much of a difference. What is also noticeable is there seems to be less ghosting of previous text if you don’t have full refresh on page flip enabled. It also has grouped all the dictionaries into one group which is nice.
It hasn’t auto pushed to mine yet so I jumped here to download it and install it manually.
