Ledger updated firmware for their Nano S version and latest version is now 2.0.0 with some important changes, and one thing I noticed is they again reduced available space for apps to only
144Kb because their operating system size increased.
They claim there are some new important features and enhancements, but we can't really review their closed source code and we can't verify anything they say.
According to ledger blog, most of the changes are related with redesign, better user experience and supporting altcoins like eth2.0.
They added progress bar that I noticed while updating my device, and added separate settings for PIN Lock and screensaver, and removed firmware upgrade identifier.
Read more details in their blog post and let the testing begin
I see people already started to complain in twitter...
