From 463d126a9f1ae20a9c34c8026b3b9a6ac6f7200e Mon Sep 17 00:00:00 2001 From: Cody Boone Ferguson <53008573+xexyl@users.noreply.github.com> Date: Thu, 18 Apr 2024 04:14:51 -0700 Subject: [PATCH 1/2] Improve thanks-for-fixes up through 1992 For each YYYY header it is a link to the respective index.html page.
