This one is particularly critical to your intended meaning as I read it:
-before a <tt class="docutils literal"><span class="pre">.post345</span></tt> marker.
+before a <tt class="docutils literal"><span class="pre">.post456</span></tt> marker.

Technical question:

I don't know what notation this versioning schema was trying for, especially in regards to what the +'s mean:
N.N[.N]+[abc]N[.N]+[.postN+][.devN+]
Am I missing something here? You could maybe explain what the pluses mean in the PEP, and why some are inside the [] and others are outside.

Or a regular expression version like this might be more specific. 
N.N(.N)?([abc]N(.N)?)?(.postN)?(.devN)?

Or an linux help version like this may be more readible.
N.N[.N][{abc}N[.N]][.postN][.devN]
