回答1:

According to the abstract in the online edition,

POSIX.1-2008 is simultaneously IEEE Std 1003.1™-2008 and The Open Group Technical Standard Base Specifications, Issue 7. This 2013 Edition includes IEEE Std 1003.1-2008/Cor 1-2013 incorporated into IEEE Std 1003.1-2008 (the base document). The 2013 edition incorporates Technical Corrigendum 1 addressing problems discovered since the approval of the 2008 edition.

Technical Corrigendum 1, containing the change-set as a big, disorganized "patch," is freely available from IEC. It appears that most if not all changes can also be browsed in their bug tracker by querying attached bugs to the tc1-2008 tag. A quick glance shows minor clarifications and changes covering everything from regular expressions to the filesystem to setjmp.
