man-pages-3.21 is released

A few days ago, I uploaded man-pages-3.21 into the release directory (or view the online pages). Notable changes in man-pages-3.21 are:

• A new pthread_setconcurrency(3) page documents pthread_setconcurrency() and pthread_getconcurrency().
• A new pthread_yield(3) page documents pthread_yield().
• The feature_test_macro(7) page adds information on the changes that glibc 2.10 makes for alignment with POSIX.1-2008, and adds an example program that can be used to display the feature test macros that are implicitly defined by particular glibc versions and as a consequence of explicitly setting macros.
