+# Release v0.31.3
+
+## Notes
+
+Thank you to all that contributed with flushing out issues and enhancements for K9s!
+I'll try to mark some of these issues as fixed. But if you don't mind grab the latest rev
+and see if we're happier with some of the fixes!
+If you've filed an issue please help me verify and close.
+
+Your support, kindness and awesome suggestions to make K9s better are, as ever, very much noted and appreciated!
+Also big thanks to all that have allocated their own time to help others on both slack and on this repo!!
+
+As you may know, K9s is not pimped out by corps with deep pockets, thus if you feel K9s is helping your Kubernetes journey,
+please consider joining our [sponsorship program](https://github.com/sponsors/derailed) and/or make some noise on social! [@kitesurfer](https://twitter.com/kitesurfer)
+
+On Slack? Please join us [K9slackers](https://join.slack.com/t/k9sers/shared_invite/enQtOTA5MDEyNzI5MTU0LWQ1ZGI3MzliYzZhZWEyNzYxYzA3NjE0YTk1YmFmNzViZjIyNzhkZGI0MmJjYzhlNjdlMGJhYzE2ZGU1NjkyNTM)

+## Maintenance Release!
+
+The aftermath...
+
+Thank you all for pitching in and helping flesh out issues!!
+
+Please make sure to add gory details to issues ie relevant configs, debug logs, etc...
+
+Comments like: `same here!` doesn't really help us zero in. Everyone has slightly different settings/platforms so every little bits of info helps with the resolves.
+Thank you!!
