From: Jakub Jelinek <jakub@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org, libstdc++-cvs@gcc.gnu.org Subject: [gcc r11-6403] Rotate ChangeLog files - step 2 - remove 2020 entries from ChangeLog files. Date: Fri, 1 Jan 2021 16:30:51 +0000 (GMT) [thread overview] Message-ID: <20210101163051.C6DCA3858D29@sourceware.org> (raw) https://gcc.gnu.org/g:618e665a0f406a7b35f449a54b322d49f8eb62af commit r11-6403-g618e665a0f406a7b35f449a54b322d49f8eb62af Author: Jakub Jelinek <jakub@redhat.com> Date: Fri Jan 1 17:30:04 2021 +0100 Rotate ChangeLog files - step 2 - remove 2020 entries from ChangeLog files. Can't be committed together with the previous one due to the ChangeLog vs. other files restrictions.
