2.9.10 Release

LinuxCNC 2.9.10 has been released.

"What happened to 2.9.9?" you might ask. The answer is that it was briefly
released then withdrawn when it was found that a bug-fix had broken
existing configs which were working-round the bug. 
Context in this [forum thread](forum.linuxcnc.org/38-general-linuxcnc-q...rd-behaviour?start=0)
 
Changelog for 2.9.10:

  * Merge pull request #4219 from grandixximo/fix/4216-applied-tlo-params
  * tests: restore #5401-#5409 loaded-offset assertions
  * interp: split loaded vs applied tool offset params (#5401-#5409, #5081-#5089)
  * Merge pull request #4211 from BsAtHome/fix_libboost_python-versioning-2.9
  * build: Select the libboost_python matching the python version.


And here is the 2.9.9 release note: 

This is a bugfix, feature improvement, and security enhancement release. 

To address the last part first, it has been noted by two separate people
that a weakness in the RTAPI allows for privilege escalation as it runs
as setuid root (to give direct access to hardware). 
Given the use-case for most LinuxCNC machines this is unlilely to be a
problem in the majority cases; most hobby users will have root access
anyway. The issue has been patched in both 2.9 and in the development
branch.
