In reading many post for the past few months one of the main reasons Discourse admins run into problems is that certain plugin upgrades cause problems.
If certain plugin versions are marked as stable then for those not needing the latest and greatest versions, we can wait for a stable version instead of clicking the upgrade button and crossing our fingers.
The new plugin version pinning feature is the way forward.
In the meanwhile, for plugins that do not support that (yet), we - as an independent third party - maintain a Github account with plugin forks on commits that are compatible with latest stable. Most plugins there are also tagged for older versions.
Espero que o novo sistema de fixação reduza os problemas de manutenção para todos os lados!
A Communiteq (antiga DiscourseHosting) provavelmente percebe isso com mais frequência, já que vocês seguem a versão estável por padrão, enquanto a hospedagem da CDCK segue a versão tests-passed. Sinta-se à vontade para enviar PRs com arquivos .discourse-compatibility para que possamos dar o pontapé inicial, pelo menos para os plugins populares e principais!
