This script has been obsoleted by phab:T207562 (and gerrit:640761), which implemented the functionality of this script in MediaWiki.
Historically, this script made the timestamps in Special:Log into links; the link for each entry went to the Special:Log page for only that entry.
The script was started on 16 August 2018 and had most recently been updated on 10 May 2020; the original idea for the script came from L235.
The source code can be found at the history of User:Enterprisey/links-in-logs.js.
