This is the second release in the v6 family.

IMPORTANT
The release is based on a refork of the PMIx master branch as the changes since v6.0.0 were extensive. Many of the changes were bug fixes, but the following significant changes are included:

• build requirements for Git clones includes a minimum
  Python version of 3.6 - the requirement does not apply
  to builds from tarball
• server upcalls no longer require that the upcall return
  prior to the server executing the provided callback
  function
• all APIs are now threadshifted prior to execution for
  thread safety. Hosts that are providing their own
  progress engine (in lieu of using the PMIx internal
  progress thread) must ensure that progress is being
  provided sufficient to avoid threadlock when calling
  PMIx APIs.
• listener thread ports can now be specified as a comma-delimited
  list of ranges instead of only a single port
• connection authentication has been tightened and greater
  controls provided via attributes
• support for process and node statistics gathering has
  been added as per the Standard
• a new API (PMIx_Progress_thread_stop) has been added to
  direct that the internal progress thread be stopped. This
  allows the host to stop the progress thread independent
  from calling a PMIx "finalize" routine.

NOTE
The v5.0 release series may be going dormant after this release.

IMPORTANT
This release includes three critical changes:

• a fix for a bug that apparently went undetected for a long time. The bug prevented selection of the loopback interface on a node for use by the PMIx messaging system, even when no remote connections were allowed. This prevented PMIx from working in an environment where only loopback devices were available.
• re-enabling of the compression support. An undetected typo caused PMIx to disable compression even when the supporting libz (or libzng) libraries were present
• repair of the indirect debugger connection procedure. Hardening of the authentication procedure inadvertently prevented tools fork'd by PMIx itself from connecting back to the server.

Detailed changes include:

• PR #3781: Multiple commits
  • Update NEWS and VERSION for release
  • Improve description of PMIx_Compute_distances API
  • Silence valgrind issues

This is the first release in the v6 family. The intent for this series is to provide regular "reference tags", effectively serving as milestones for any development that might occur after the project achieved a stable landing zone at the conclusion of the v5 series. It is expected, therefore, that releases shall be infrequent and rare occurrences, primarily driven by the completion of some significant feature or some particularly critical bug fix.

For this initial release, that feature is completion of the Group family of APIs. This includes support for all three of the group construction modes, including the new "bootstrap" method. A description of each mode can be found in the Group Construction section of the documentation.

A few notes:

1. Proper execution of the various group construction modes requires that the host provide the necessary backend support. Please check with your host provider to ensure it is available, or feel free to use the PMIx Reference RunTime Environment - you will require v4.0 or above.

2. Starting with this release, PMIx requires Python >= v3.7 to build a Git clone (ie., not a tarball). Certain elements of the code base are constructed at build time, with the construction performed by Python script. The constructed elements are included in release tarballs.

3. PRRTE < v4.0 is not compatible with PMIx >= v6.0 due to internal changes (e.g., show-help messages are now contained in memory instead of on-disk files).

A full list of individual changes will not be provided here, but will commence with the v6.0.1 release.

** WARNING **
This release contains a patch required for all servers that enable tool connections. Minus the patch, PMIx may over-aggressively cleanup files from the temporary directory that it did not create. The precise timing of the bug's introduction to the release series is unclear. Thus, all users are advised to update to this version as soon as possible.

Detailed changes include:

• PR #3479: Multiple commits
  • Cleanup a segfault when the host refuses group construct support
  • Update PRRTE CI to point at PRRTE v3.0 branch
