Thanks for offering these translations @mrmuminov.

I can look to merge these in for the next feature release.
Providing translations via GitHub, especially with this many changes, can cause trouble with our primary system of translation (Our Crowdin Project).

To include these changes, I would look to upload your changes via Crowdin, so they're included back into the project via Sync from Crowdin, rather than merging this GitHub PR.
Are you okay with that? You won't show as a contributor via Git history via this but you will be added to the translator contributor list.

@ssddanbrown good
I agree
main thing for me is to accept changes and improve and develop my (Uzbek) language.

Thanks for confirming @mrmuminov,
Translations are now in Crowdin at https://crowdin.com/project/bookstack/uz, these will enter BookStack via #4523 for next release.

Language & attribution added in 4ec600a.
Will therefore close this off.
