Welcome to 2023. This month’s newsletter is mostly about development updates, but we also want to know what you think about Zeek!

We’re running a survey until 10 February – no login or identifiers required unless you want to talk with us directly. Share your thoughts on how you use Zeek to defend your environment or conduct network research:


Development Updates

On 5 January, Arne Welzel announced that Krisan Timur had transferred control of the “zeek” Docker Hub account to the Zeek project. Tags from the old zeekurity/zeek account have been re-pushed to zeek/zeek and the latest documentation is now updated. We plan to retire the “zeekurity” account in the future and recommend changing to “zeek” if you’re consuming these images.

On 9 January, Tim Wojtulewicz announced the release of Zeek 5.0.5, a bug fix release. Please update Zeek as soon as possible.

See the release notes for details:

On 20 January, Benjamin Bannier announced the release of Spicy 1.5.3. This is a bug fix release for the 1.5 Spicy release series we maintain for long-term support in Zeek LTS.

On 25 January, Benjamin Bannier announced the release of Spicy 1.6.1. See the NEWS file for a high-level summary, or the CHANGES file for a detailed list of changes.
