As you can see below, there've been many changes since the last Brim GA release! Highlights include:

  • The storage used by Brim to hold your logs is now a Zed lake. Though the introduction of Zed lakes causes no immediate change to your favorite Brim workflows, they unlock powerful new functionality that will be revealed in Brim going forward, including Git-like branching. See the Zed lake README for details.
  • Enhancements have been made to the Zed language to unify search and expression syntax, introduce new operators and functions for data exploration and shaping, and more! Review the Zed language docs for details.
  • pcap processing is now handled by a separate, new component called Brimcap. Your favorite pcap workflows in Brim have not changed, but Brimcap also opens up new flexible custom configurations and can be used as a standalone tool. For more info, check out the Brimcap README and wiki.

Among the many detailed changes listed below, there're a few big ones in particular we'd like to bring to your attention first.

  • You will be prompted upon first launch of Brim v0.25.0 to allow auto-migration of saved data from your v0.24.0 Spaces to pools in Zed lakes. See the Space Migration article in the Brim wiki for details.

  • Brim v0.25.0 includes a new installer that will make upgrades to future versions more seamless. However, when making the jump from v0.24.0 to the newer release:

    • Windows users will not be prompted to auto-update as they were in the past. Windows users will also have to manually uninstall the old release before v0.25.0 will start. Auto-update notifications for Windows will resume on the next release. See the Installation article on the Brim wiki for details.
    • Linux users of RPM packages (such as for Red Hat-style distributions) will need to uninstall the older v0.24.0 release before the RPM package for v0.25.0 will successfully install. See the Linux RPM Upgrade article in the Brim wiki for details.

    Note that a Brim uninstall does not disturb the data you've saved in the app. See the Filesystem Paths article in the Brim wiki for details of how Brim stores user data separately from app binaries.

  • When upgrading to v0.25.0, the pre-installed entries in the Query Library are auto-updated to adapt to new Zed language syntax. However, if you've saved custom entries to the Query Library, you'll need to change these yourself. Some key changes include := now being used for assignment, == for equality comparisons, and string values must now be quoted in field/value matches.

The exhaustive set of changes is listed below. Come talk to us on Slack if you have additional questions.

  • Remove the legacy approach for applying Zed types to NDJSON input, as this is now done via Zed shapers (docs) (#1580, #1582)

NOTE - Beginning with this release, a subset of the source code in the github.com/brimsec/brim GitHub repository is covered by a source-available style license, the Polyform Perimeter License (PPL). We've moved the PPL-covered code under a ppl/ directory in the repository. The majority of our source code retains the existing BSD-3-Clause license.

The overwhelming majority of Brim users and developers will not be impacted by this change, including those using Brim in commercial settings. The use of the source-available Polyform Perimeter license prevents use cases like marketing a work as a replacement for the Brim desktop application while using material covered under the PPL.

In general, we are making this change to ensure technology giants can't use the PPL-covered code to make replacement offerings of our projects. We believe users and developers should have access to the source code for our projects, and we need a sustainable business model to continue funding our work. Using the source-available Polyform Perimeter license on portions of the source code lets us realize both.

For more detail regarding licensing, see the CONTRIBUTING.md doc, and feel free to come talk to us on Slack if you have additional questions.


NOTICE for users who have added custom entries to their Query Library:

We've become aware of an issue in Brim v0.22.0 where custom entries in the Query Library will not be saved if you quit by closing all your Brim windows (i.e. hitting the "X" in the upper-right of the window on Windows/Linux, or clicking the "red stoplights" on macOS). They are saved if you quit via the pull-down menu (File > Exit on Windows/Linux, Brim > Quit Brim on macOS). Therefore, when closing Brim in prep for the v0.23.0 upgrade, make sure you quit via pull-down menu. When you're prompted to auto-update to v0.23.0 on Windows/macOS, select the option to Restart Later so that way you can quit via pull-down menu. We've fixed these issues so it should not be a problem in v0.23.0 and going forward. Sorry for the inconvenience!


  • Update zq to v0.28.0
  • Revise the Troubleshooting doc to describe the use of the Window > Reset State pull-down menu option (#1350)
  • Fix an issue where scrolling to the bottom of the main window did not bring up additional events (#1348)
  • Fix an issue with inconsistently-created pinned items in the History panel (#1349)
  • Adjust the configuration for log generation in the embedded zqd (#1353)
  • Fix an issue where "Restart Required" notifications in the Preferences screen were not fully visible (#1368)
  • Fix an issue where results in the "MD5 correlation" visualization were not being updated after event tiles were clicked (#1369)
  • Disable the creation of macOS filesystem tags during Export operations (#1370)
  • Fix issues where Query Library entries were being lost when exiting/relaunching Brim (#1366, #1387)
  • Add a right-click option to Copy field contents into the paste buffer (#1367, #1381)
  • A "Connection" (such as to a remote zqd) is now known as a "Workspace" (#1372)
  • Revise the Troubleshooting doc with more detail regarding failures to open flows from pcaps (#1380)
  • Windows releases are signed, but you may see a warning popup when you run the installer (unlike our Mac/Linux releases). See Microsoft Windows beta limitations for details.

NOTE - The Brim v0.21.0 release includes initial support for the automatic generation of Suricata alerts from imported pcaps. The alert records may be isolated via a ZQL search event_type=alert and are also included automatically alongside relevant Zeek event context in the correlation visualization in the Log Detail view. The Suricata build that's packaged with Brim uses the Emerging Threats Open ruleset, and Brim triggers a download of the most recent set of these rules each time it is launched.

There are two known issues found during testing that may be bugs in Suricata that impact the correctness of the alerts seen in Brim:

  • When run on a system under heavy load, Suricata has sometimes been observed to generate fewer alerts than expected (or none at all) for a given pcap.
  • Alerts may be generated with timestamps that are seconds/minutes further into the future beyond the end of the time range of the flow that triggered them.

These issues are still being investigated and more information will be provided as they're better understood. More Suricata-related functionality is also planned in upcoming releases. For now, please contact us on Slack or open an issue if you have any questions or problems with the new Suricata support, including incidents of the issues described above.

  • Add Suricata support to generate alerts from imported pcaps (#1207)

  • Add a wiki doc with details for using Brim with a remote zqd (#1222, #1252)
  • Add a wiki doc with basic Brim installation guidance (#1253, #1260)
  • Add a "Sectional" package in the code that allows a view to be split (#1247)
  • Add a "Tree list" package in the code for working with lists (rendering, drag & drop, etc.) (#1254)
  • Fix an issue where Brim would freeze during zoom-in/zoom-out (#1275)
  • Fix an issue where autoupdate would install releases with version numbers "older" than the number of the one currently installed (#1244)

  • Fix an issue on Windows where clicking records generated from an imported pcap produced error messages (#1287)

  • NOTE - Due to the ZNG storage format change described in the zq v0.23.0 release notes, when you first launch the new version of Brim, a one-time bulk background update of the stored data for all of your existing Spaces will automatically begin. If you click to access a Space while migration is in progress, an animated "spinner" will be visible in the right of the Search bar. Once migration is complete for a Space, the bar chart will be filled in and the first splash of events will be shown and you can begin working with your Space as usual.
