Please upgrade to 1.16.1, and feel free to reopen if there is still an issue.

Hmm, I found that there is a bug:

Introduced by:

• Add simple update checker to Gitea #17212

Need to improve:

1. Incorrect leading "
2. No i18n
3. <a> should have target=_blank
4. {{.AppVer ... is incorrect, "AppVer" is a function, so it should be {{AppVer ...}}

				<p>"Gitea {{.RemoteVersion | Str2html}} is now available, you are running {{.AppVer | Str2html}}. Check the <a href="https://blog.gitea.io">blog</a> for more details.</p>
