[BuildStream] BuildStream 1.4.3 released

[Tristan Van Berkom <tristan vanberkom codethink co uk>]

Hi all,

Here is another bugfix release in the 1.4.x series.

This one has a couple of critical bugfixes, if you have experienced
BuildStream no longer working when trying to download files from
gitlab.com as of recently, this release fixes that issue.


What is BuildStream ?
=====================
BuildStream is a Free Software tool for building/integrating software
stacks. It takes inspiration, lessons and use-cases from various
projects including OBS, Reproducible Builds, Yocto, Baserock,
Buildroot, Aboriginal, GNOME Continuous, JHBuild, Flatpak Builder and
Android repo.

BuildStream supports multiple build-systems (e.g. autotools, cmake,
distutils, make, meson), and can create outputs in a range of formats
(e.g. debian packages, flatpak runtimes, sysroots, system images) for
multiple platforms and chipsets.


=================
buildstream 1.4.3
=================

  o Fix support for conditional list append/prepend in project.conf,
    Merge request !1857

  o Fix internal imports to import from "collections" instead
    of "collections.abc", this improves support for Python 3.8,
    see issue #831

  o Fix some downloads from gitlab.com by setting custom user agent,
    fixes issue #1285

  o Work around python API break from ostree's
    repo.remote_gpg_import(), this was changed in ostree commit
    v2019.2-10-gaa5df899, and we now have a fallback to support both
    versions of the API, see merge request !1917.
