| Summary -- Release highlights |
| ============================= |
| |
| Note Bene for alpha users: Do not upgrade unless you want to |
| test things out. Some changes will require a configuration change, |
| that won't be compatible with 2.x. For example some extensions |
| were removed in favor of a builtin message (``compare-to-zero`` |
| and ``compare-to-empty-string``). We'll make a configuration |
| upgrade tool available before 3.0.0 is out. |
| |
| Pylint now provides some important usability and performance improvements, |
| along with enacting necessary breaking changes and long-announced deprecations. |
| |
| There's going to be frequent beta releases, |
| before the official releases, everyone is welcome to try the betas |
| so we find problems before the actual release. |
| |
| The required ``astroid`` version is now 3.0.0. See the |
| `astroid changelog <https://pylint.readthedocs.io/projects/astroid/en/latest/changelog.html#what-s-new-in-astroid-3-0-0>`_ |
| for additional fixes, features, and performance improvements applicable to pylint. |
| |
| A new ``json2`` reporter has been added. It features an enriched output that is |
| easier to parse and provides more info, here's a sample output. |
