 Also, the PBS "release tag" will be inferred for PBS releases supplied via the `--python-build-standalone-known-python-versions` option from the given URLs if those URLs conform to the naming convention used by the PBS project. The new advanced option `--python-build-standalone-require-inferrable-release-tag` controls whether Pants requires the tag to be inferrable. This option currently defaults to `False`, but will be migrated to `True` in a future Pants release. (The release tag cannot currently be specified via `--python-build-standalone-known-python-versions` since changing that option would not be a backward compatible change.)
