From 252457d4b21f46889eebad61d4c0a65331919cec Mon Sep 17 00:00:00 2001 From: Jack Rosenthal Date: Thu, 4 Nov 2021 12:11:58 -0600 Subject: ish: Trim down the release branch In the interest of making long-term branch maintenance incur as little technical debt on us as possible, we should not maintain any files on the branch we are not actually using. This has the added effect of making it extremely clear when merging CLs from the main branch when changes have the possibility to affect us. The follow-on CL adds a convenience script to actually pull updates from the main branch and generate a CL for the update.
