 - [BUGFIX] Patch RPATHs of non-Python extension dependencies ([#136](https://github.com/pypa/auditwheel/issues/136), [#298](https://github.com/pypa/auditwheel/pull/298))
 - [BUGFIX] Ensure policies in `policy.json` are compliant with PEP600 ([#287](https://github.com/pypa/auditwheel/pull/287))
-  - This removes 2 non existing symbols from manylinux1 i686 policy and removes ncurses librairies from manylinux1 whitelist.

   - The platform tag passed to `auditwheel repair` `--plat` argument can use either the PEP600 tag or the legacy tag. The repaired wheel will get both platform tags.
   - Inform about aliases in `auditwheel repair --help`
 - [FEATURE] Always repair as a single wheel ([#289](https://github.com/pypa/auditwheel/pull/289))
-  - Add argument `--only-plat` to `auditwheel repair` for those who were keeping only the lowest priority tag wheel (i.e. the one requested by `--plat` argument).
