tankerkiller125 it's safer to run composer update
with some more arguments in order to not update everything at once. I believe you could do something like (written out of the top of my head, untested) composer update s9e/text-formatter
to update just the text formatter, or composer update flarum/core --with-all-dependencies
to update core and all its dependencies.
Running update without arguments will also update all extensions immediately and could make it harder to debug an issue if something breaks after the command.
