Subject: PVXS release 1.5.0 and P4P 4.2.2

PVXS 1.5.0 and P4P 4.2.2 are now available in the usual places. 

These are bug fix releases.  The switch from PVXS 1.4.x to 1.5x is due to an ABI change in libpvxsIoc to avoid a symbol name clash with libqsrv.

I anticipate that these will be the final releases supporting python 2.7 or 3.7.

For these releases, the set of binaries uploaded to pypi.org is reduced to only cpython 3.8 through 3.14 for Linux/amd64, OSX/universal, and Win64.  py2.7 and py3.7 support is still tested, but anyone still using these versions will need to build from source.
