New version of pcsc-lite: 2.4.1

I have just released a new version of pcsc-lite 2.4.1.

pcsc-lite is a Free Software implementation of the PC/SC (also known as WinSCard) API for Unix systems. It provides an API for using smart cards and smart card readers.

This version offers backwards compatibility for both the client and server components. It should now be easier to mix and match different versions of pcscd and libpcsclite (and using different internal protocol versions).

Changes:

2.4.1: Ludovic Rousseau

  • Add backward version support on the client side

  • meson: install systemd files even if libsystemd is not used

  • Some other minor improvements
