# 16.2. PRRTE v2.x series

This file contains all the NEWS updates for all the PRRTE v2.x series, in reverse chronological order.

## 16.2.1. 2.0.2 – 11 Feb 2022

Important

This release contains a workaround that resolves the prior conflict with HWLOC versions 2.5.0 through 2.7.0 (inclusive). Those versions of HWLOC are now supported.

- PR #1197: Cleanup a bit in prep for PMIx v5 release

- PR #1195: Remove HWLOC version block

- PR #1190: Add missing examples to tarball

- PR #1189: Ensure an error gets reported when rankfile fails

## 16.2.2. 2.0.1 – 1 Feb 2022

Important

As of v2.0.1, PRRTE no longer has a dependency on “pandoc” for building and installing man pages.

Important

PRRTE has identified a bug in HWLOC versions 2.5.0 thru 2.7.0 (inclusive) that causes PMIx to segfault during certain operations. We have worked with the HWLOC developers to fix that problem, and the fix will be included beginning in HWLOC version 2.7.1. Accordingly, PRRTE now checks for the problem HWLOC versions and will error out of configure if they are encountered.

## 16.2.3. 2.0.0 – 29 Jul 2021

Important

This is the initial production release of the PRRTE software system. It contains full support of the PMIx v4.1 Standard plus extensions as provided by OpenPMIx v4.1. It therefore requires support from that release or above.

Delineating all the changes from the original v1.0.0 tarball would be overwhelming. The original tarball was provided solely as a means for packagers to prepare for the eventual production version and was not intended for general use. As expected, the code base has been extensively revised/rewritten since that time.

Further changes shall be tracked here in follow-on releases.
