New version of pcsc-lite: 1.8.26

I just released a new version of pcsc-lite 1.8.26.
pcsc-lite is a Free Software implementation of the PC/SC (or WinSCard) API for Unix systems.

  • Doxygen: fix minor issues in the documentation

Motivation

The major change is the use of reader filtering by default. No need to rebuild pcsc-lite using --enable-filter any more.
The feature was introduced in 2015 and is documented at "Remove and/or customize PC/SC reader names".

This feature is requested in packages by some users.

To avoid that each GNU/Linux distribution changes the packaging configuration to enable the feature I decided to enable the feature by default in the upstream project.

This change should not have any bad side effect. Only root can modify the configuration file /etc/default/pcscd or the systemd file /etc/systemd/system/pcscd.service.d/override.conf.

For systemd use: sudo systemctl edit pcscd to add something like:
[Service]
Environment=PCSCLITE_FILTER_IGNORE_READER_NAMES=Nitrokey

You can get the previous behaviour by using
./configure --disable-filter
