With 1297 changes, we're a bit lower than the previous cycle that had a
bit more than 1400 changes, but we're still very active. These
contributions came from 119 contributors, a number that is stable
compared to our previous release. This seems to be very much in line
with how Buildroot has been developed over the past few years, through
a continuous and regular stream of contributions, coming from a
significant contributor base.

Of noteworthy new features/changes in this release we have:

 - Addition of support for gobject-introspection: both the
   gobject-introspection package itself, but also introspection
   support was enabled in a number of other packages.

 - Support for Qt 5.6 was dropped as its support was dropped
   upstream, only one version of Qt is supported at the moment:
   Qt 5.14.2.

 - Addition of support for the apparmor Linux security module, by
   adding the necessary user-space packages.

 - Addition of a qmake package infrastructure, now used by most
   Qt-related packages.

 - The Luarocks package infrastructure has been extended to
   support build host packages.

 - The package infrastructure was improved to allow each package
   to indicate the Linux kernel configuration options it needs.

 - Addition of support for generating filesystem images using the
   EROFS filesystem.

 - The logic that calculates the list of files installed by each
   package was reworked to be compatible with the top-level
   parallel build functionality.

 - Addition of a package for a pre-compiled ARM32 bare-metal
   toolchain, which can be used to build ARM32 code in ARM64
   configurations, such as firmware/bootloader code.

 - The Qemu defconfigs are now boot-tested in Qemu as part of the
   Gitlab continuous integration.

 - Toolchain: gcc 9.x bumped to 9.3.0, gcc 8.x bumped to 8.4.0,
   gdb bumped to 8.3.1.

 - New packages: apcupsd, apparmor, arm-gnu-a-toolchain, bearssl,
   belle-sip, belr, cage, chartjs, erofs-utils, exfatprogs,

You can expect the final 2020.05 release by the end of May. Since -rc1
has been released, we will now only merge fixes into the master branch,
which will become the final 2020.05 release at the end of May. However,
in order to not stop the merging of new features for 2020.08, we have
also opened a 'next' branch in which new features and version bumps
that are not security updates will be merged.

Best regards,

Thomas Petazzoni
