Hello all,

The time in the year has come again!

You can find a release candidate for OpenSC version 0.24.0 for testing 
on Github:

The notable changes include potential PIN bypass in PIV driver as well 
as several potentially security related memory or buffer issues found by 
oss-fuzz. We also enabled file caching by default, improved support for 
several IDPrime card types, implemented Secure Messaging for PIV and 
added support for EC in Minidriver.
