   * Remove pointless Recommends from launchpad-dependencies to
     launchpad-database-dependencies.
   * Remove Recommends on postgresql-doc-9.3; wasn't up to date, and can
     easily be viewed online.
+  * Remove Recommends on bzr-lpreview-body, no longer relevant now that we
+    use git.
+  * Remove Recommends on pyflakes; we use pre-commit for lint checking
+    nowadays.
+  * Remove dependency on bzr.
+  * Remove Recommends on subunit; zope.testrunner uses this from Launchpad's
+    virtualenv, while buildbot workers use subunit-2to1 either from the
+    system package on the worker host (currently) or the virtualenv (soon).
+  * Remove dependency on postgresql-plpython-10, since we no longer use
+    PL/Python 2.
+  * Remove python-convoy, now that production uses python3-convoy.
+  * Add gnupg2 to launchpad-dependencies so that we can migrate to it.
+
+  [ Andrey Fedoseev ]
+  * Add firefox-geckodriver to launchpad-developer-dependencies;
+    this is required for Selenium-based test browser
+  * Remove gir1.2-* dependencies; it is superseded with firefox/selenium.
+
+  [ Guruprasad Lakshmi Narayanan ]
+  * Add PostgreSQL 12 support.
+  * Depend on libgpgme-dev if libgpgme11-dev is unavailable.
