this is only for setting the default user language during registration based on the browsers accept language headers.

this is likely related to https://github.com/LemmyNet/lemmy/issues/4971

this isn't true. it was incorrectly stated in the upgrade guide but has been removed a while ago. it was supposed to be a recommendation due to some issues with postgres 15. there is no postgres upgrade required between 0.19 releases.

account names cannot be changed.

you can only change your display name, which is available in the settings.

whether display names or usernames are shown depends on the interface/client and user settings where available.

the only way to change the username is to create a new account.

it seems to have become more frequent recently.

i've been experiencing the same on firefox and i've also heard other people report the same on firefox, which happened around the time of the firefox 129 release. i didn't see anything noteworthy in the release notes though that'd explain this. it seems like it might be related to enhanced tracking protection and cookie isolation.

this is a lemm.ee limitation, not a Lemmy limitation, so this is the wrong community.

if you look at the instance sidebar at https://lemm.ee/ you can see that it's 4 weeks.

for sure, but they're neither mentioned on https://join-lemmy.org/docs/users/02-media.html nor on the linked CommonMark tutorial.

It's not even just that. It seems that the extra @ acts as a separator, so you can't even autocomplete e.g. @threelonmusketeers@sh as that'll try to autocomplete @sh instead of taking the instance domain as part of the mention.

I've raised a GitHub issue for this now: https://github.com/LemmyNet/lemmy-ui/issues/2652

on firefox, if i type @gedal and click or press tab once it replaces the text with [@gedaliyah@lemmy.world](https://lemmy.world/u/gedaliyah) . the behavior is the same whether i hit tab, enter or click the text.

just as great as lemmy-ui

it does, but only if you use the autocomplete feature. it's also a bit delayed without any indicator that it's loading.

if you type @gedal and wait a moment it'll load @gedaliyah@lemmy.world to be selected:
