What is the different between them?

Hi! I get a little confuse with PHP version x.x.xpl1 and version x.x.xpl2. What is the different between them?

pl1= patch level 1, pl2 = patch level 2

patch levels are used to indicate bug-fixes that were not severe enough to warrant a new version number.

4.1.1 = new release
4.1.1pl1 = 4.1.1 with some bugs fixed
4.1.1.pl2 = 4.1.1 with more bugs fixed
4.1.2 = 4.1.1 with bugs fixed and new features added/changes made.
