Additional Context
Affected file
1.architectures/2.aws-parallelcluster/README.md — three occurrences:
| Line | Current | Fix |
|---|---|---|
| 68 | export PCLUSTER_VERSION=3.13.1 |
export PCLUSTER_VERSION=3.14.2 |
| 336 | PCLUSTER_VERSION: 3.13.1 (example config) |
PCLUSTER_VERSION: 3.14.2 |
| 413 | "version": "3.13.0" (example JSON output) |
"version": "3.14.2" |
Note: line 413 already has a minor inconsistency — it says 3.13.0 while the rest of the file says 3.13.1. This should also be corrected to 3.14.2.
