[Trisquel-announce] Release announcement: Trisquel 9.0.1 Etiona security update

[Ruben Rodriguez]

[Re-sending announcement due to previous issues in the mail servers]

Images are available at https://trisquel.info/download or directly at
https://cdimage.trisquel.info/ and its mirrors.

This minor update to the 9.x "Etiona" series is intended to provide an
up to date set of ISO images, both for use as an installation medium and
as a live environment with newer packages. This addresses two main
security concerns in the 9.0 original ISO images:

 * An outdated Certificate Authority collection (package
ca-certificates) included an expired root certificate for LetsEncrypt,
resulting in blocked access to repositories for new packages or updates.

 * Overlooked binary blobs were found in versions of Linux-Libre prior
to v5.14. Updated packages were added to the Trisquel repositories to
correct the issue, and new ISO images were produced to include the fix.

Along with those fixes, the release includes any other security update
published upstream since we published Etiona, and the latest version of
the Mozilla-based "Abrowser" (v93).

These updates will contribute to keep the v9.0 branch in good working
order as it will continue to be actively maintained until April 2023.

In other news, the development of Trisquel 10 is ongoing at great pace,
with initial ISO images being now available for testing at
https://cdbuilds.trisquel.org/nabia/ Please note that these images are
not yet intended for production usage, so use them only for testing and
development or (as it is true in any case) at your own risk.
