Equo May Product Update
Juan Farah and Gabriel Beghelini on June 8th 2026
What's in this update
This month, we're covering the latest updates across Equo Chromium v138 and v144, and an important milestone for SWT Evolve: NatTable support is ready. May brought a solid combination of new developer-facing capabilities, targeted stability work, and a significant new addition to the Eclipse application ecosystem.
Both versions received a meaningful set of shared improvements, highlighted together to avoid repetition. Beyond that, 144 continues to make strong progress for teams building desktop applications with standalone, with several advances worth a closer look. 138, on the other hand, was focused entirely on stability and maintenance this month, bringing it up to full parity on every shared fix.
Here is what shipped.
Shared improvements — v138 and v144
Context menu customization
Both v138 and v144 now let teams customize the context menu in embedded browser windows. Rather than presenting users with a standard Chromium menu filled with options that don't belong in a desktop application, developers can now define exactly what appears. It's a small change with a noticeable impact on how polished the embedded browser experience feels to end users.
Wayland and Linux stability
A comprehensive batch of Wayland-related fixes landed across both versions for SWT applications on Linux. This covers focus handling when switching between tabs, context menu display, tab visibility, incorrect window visibility, unexpected shutdowns after application close, and a restart stability issue on Linux. For teams running Equo Chromium in modern Linux environments, this update brings a noticeably more reliable experience.
Windows and download reliability
An issue affecting method documentation preview in SWT on Windows was resolved in both versions. Download dialog behavior was also restored to its expected default across Swing, Standalone, and SWT, including a fix for an empty filename field that appeared in SWT download dialogs.
What's new in v144
Beyond the shared improvements, v144 saw meaningful progress on its Standalone mode; the integration path for teams using Equo Chromium without depending on SWT or Swing.
Standalone keeps expanding
Applications running in Standalone mode can now create views directly, adding an important capability for building richer desktop interfaces without a full UI toolkit. CEF thread handling was also improved for Linux and Windows, making Standalone behavior more predictable under real application conditions, and a fix now prevents premature JVM exit, an issue that could affect application lifecycle reliability.
Better window experiences on macOS
Multi-window support with Chrome Style is now available on macOS in Standalone, and Client-Side Decorations can now be used together with Chrome Style in Standalone as well. A black screen issue that appeared on macOS when closing a Client-Side Decorated window was also resolved, rounding out a more complete and dependable windowing experience for macOS users.
Additional fixes
A restart stability issue affecting SWT applications was resolved, along with a separate restart failure on Linux when using the Equo Chromium launcher library. A Windows-specific issue where downloads would not start after the dialog was also resolved, and a collision that could occur when loading multiple routers has been addressed.
What's new in v138
138's May cycle was dedicated to stability and maintenance. No new features landed exclusively in this version; instead, the focus was on ensuring that every shared improvement described above reached v138 at the same time as v144.
This means teams running v138 in production benefit from the same context menu customization, the full set of Wayland and Linux fixes, the Windows documentation preview fix, and the download dialog improvements. 138 remains an actively maintained, production-ready release, and that commitment hasn't changed.

SWT Evolve: NatTable support is ready
May wasn’t only a strong month for Equo Chromium. On the SWT Evolve side, an important milestone arrived: support for NatTable, one of the most widely used and powerful widgets in the Eclipse ecosystem.
NatTable is part of the Eclipse Nebula project and the go-to solution for high-performance data grids in Eclipse RCP and SWT applications. Teams across industries rely on it to display and interact with large, complex datasets in their desktop products. With this update, applications that use NatTable can now run through SWT Evolve, on both the desktop and in the browser, without changing a single line of code.
Download the NatTable examples
Before downloading, check the README on GitHub for instructions on how to run and explore the examples.
The work continues, and it shows.
Equo Chromium is still growing strong. May's updates are a reflection of something we hold to consistently: both actively developed versions, 138 and 144, receive real attention every month, whether that means new capabilities or the careful stability work that keeps production applications running without surprises.
The advances in v144's Standalone mode this month bring teams closer to a complete, modern path for building web-first desktop applications, without giving up the reliability and long-term support that enterprise software demands. And the Wayland, macOS, and Windows improvements reinforce that Equo Chromium is built to work well everywhere your users are.
And with SWT Evolve bringing NatTable support this month, teams across the Eclipse ecosystem have one more reason to explore what modernization looks like in practice, without touching a single line of their existing code. More is on the way. Thank you for being part of this journey.
