January update! datalust.co/blog/jan-eng...

Seq's "What's New?" page has been cumulative since 2020.1. If you've skipped a release or two, it's a fantastic way to catch up quickly on anything you might have missed 🙂 datalust.co/docs/whats-new

This year we've been in the lucky intersection of features most requested by Seq users, and deeply interesting new tech to design and build. Heading into 2026 we have a lot to unpack! @liammclennan.bsky.social started with an overview of column stores at @dddbrisbane.bsky.social this month.

The Seq team rounded out 2025 at DDD Adelaide and then DDD Brisbane a month later, both fantastic community-oriented conferences. Here's Ashley Mannix sharing his experiences shepherding Seq's high-performance #rustlang codebase through back-to-back years of rapid growth.

December Engineering Update: datalust.co/blog/decembe...

Have you ever thought about having unit tests for your unit tests? 🤔 If so, decent chance your testing isn't catching the bugs you need and is just slowing you down ⏱️ @Ashley Mannix at #DDDAdelaide 2025 shows how to test complex software, challenging what a test is 🧪

Hey that's @liammclennan.bsky.social from @datalust.co speaking at @dddadelaide.bsky.social ! Head over to dddadelaide.com to find out more and buy your ticket before they're all gone. Less than two weeks to go.

What are we working on, now? 👀 datalust.co/blog/what-ar...

👏 A big thank you to Seq for coming on board as a Silver Sponsor for DDD Brisbane 2025! Community events like DDD Brisbane wouldn’t be possible without the support of sponsors who believe in building and strengthening the local developer community.

Huge thanks to @datalust.co, makers of Seq, for continuing to support DDD events. One of only two tech companies that came to the table for our crazy outback experiment. 🙇🙇🙇 Check out Seq at datalust.co

Seq Forwarder has moved! Seq's own handy little store-and-forward ingestion proxy has been rewritten as the `seqcli forwarder` command group: github.com/datalust/seq... The original Seq Forwarder repository has been archived, but past releases will remain available there.

Superpower 3.1.0 is a maintenance release with updated TFMs, index/range support on TextSpan, and a new Text() combinator for character parsers: github.com/datalust/sup...

Work Sharing in Seq Clusters ✨ blog.datalust.co/work-sharing...

Fans of the "classic" light theme, we hear you! ❤️ The latest 2025.1 build brings this back; update, jump into your user preferences, and select "Classic Light" from the theme drop-down 😊

The nifty color palette we adopted here is based on Matteo Niccoli's perceptual rainbow palette, mycartablog.com/2013/02/21/p...

Introducing heatmaps: Seq now implements this popular visualization for three-dimensional data sets 😎 blog.datalust.co/introducing-...

What's new in `seqcli`? blog.datalust.co/whats-new-in...

We've just pushed a tiny 2025.1 patch that fixes indexing on single-core machines/containers 😅 Multi-core boxes are unaffected and can ignore this one. github.com/datalust/seq...

Self-hosting's "moment" is set to be a long one. We saw the privacy advantages a decade ago, and the momentum is only getting stronger.
