OS X El Capitan and CCID evolution

In a previous blog article "OS X El Capitan and CCID driver upgrades" I mentioned the evolution of the CCID driver for the same major release of OS X 10.11.x.

With the availability of the source code at Apple Open Source it is easy to see what happened.

OS X Version	SmartcardCCID	CCID
10.11	SmartcardCCID-55008	1.4.14
10.11.1	SmartcardCCID-55008	1.4.14
10.11.2	SmartcardCCID-55008.20.1	1.4.20
10.11.3	SmartcardCCID-55008.20.1	1.4.20
10.11.4	SmartcardCCID-55008.40.1	1.4.21
10.11.5	SmartcardCCID-55008.40.1	1.4.21
10.11.6	SmartcardCCID-55008.40.1	1.4.21

I will try to closely follow the evolution of macOS Sierra (10.12) source code to avoid surprises in the future.
