BuildStream 1.6.3 released

[Tristan Van Berkom <tr...@codethink.co.uk>]

Hi all,

This is another bugfix release in the 1.6.x stable series, it
essentially bumps the minimum required version of grpcio, and overhauls
our CI, fixing some minor issues which arise when testing against more
recent versions of python libraries.


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 1.6.3
=================

  o Support for python 3.9 now being tested in CI

  o CI overhaul to work more like it does in master

  o Refresh all dependencies which are being tested in CI, addressing
    a corner case crash that would occur when using bash completions
    and bleeding edge versions of the click library

  o Updated minimum required version of grpcio library to 1.30, as
    older versions are not working properly with existing artifact
    cache services.
