Firebird vs Zed: at a glance
What is Firebird?
Firebird maintains three release branches at once and ships the same fixes to all of them
Firebird keeps 3.0, 4.0 and 5.0 alive simultaneously, and its release notes make the arrangement obvious: the same issue numbers appear across branches, usually on the same day. Issue #8598, which stops referential-integrity triggers firing when primary or unique keys are unchanged, shipped in 5.0.3, 4.0.6 and 4.0.7 alike. The 5.0 line is where genuinely new work lands — inline small blobs, network statistics exposed to applications, subquery unnesting — while 3.0 receives little beyond dependency updates and a bug count.
What is Zed?
Zed 1.27 writes commit messages in your repo's style and trims agent memory use.
Zed ships a weekly minor plus patches. 1.27.0 adds Go 1.27 generic-method highlighting, an option to open README files in new windows, AI commit messages that copy the style of the repository's last three commits, and lazy loading that cuts Agent Panel memory and CPU on long threads. 1.26 added Pyrefly for Python and WebAssembly stepping in the JavaScript debugger.

◆ Current state
Firebird keeps 3.0, 4.0 and 5.0 alive simultaneously, and its release notes make the arrangement obvious: the same issue numbers appear across branches, usually on the same day. Issue #8598, which stops referential-integrity triggers firing when primary or unique keys are unchanged, shipped in 5.0.3, 4.0.6 and 4.0.7 alike. The 5.0 line is where genuinely new work lands — inline small blobs, network statistics exposed to applications, subquery unnesting — while 3.0 receives little beyond dependency updates and a bug count.
◆ Where it's heading
The optimizer is the focus of the current cycle. Recent releases repeatedly target NULL handling in index navigation, cardinality estimation against primary record versions and empty data pages, and avoiding index work the planner can prove unnecessary. A second thread trims client-server round trips: blob info prefetched when a blob is opened, small blobs sent inline, network statistics collected for user applications. Nothing suggests a new major version is near; the effort is going into making the existing engine faster on the queries people actually run.
◆ Prediction
Expect the 3.0 branch to keep receiving only security and dependency updates until it is retired, with 4.0 following the same trajectory. The optimizer work in 5.0.x has been steady enough across releases that more NULL-handling and cardinality refinements are the safest bet for the next one.
Zed
5.0DEVOPS
Zed 1.27 writes commit messages in your repo's style and trims agent memory use.
◆ Current state
Zed ships a weekly minor plus patches. 1.27.0 adds Go 1.27 generic-method highlighting, an option to open README files in new windows, AI commit messages that copy the style of the repository's last three commits, and lazy loading that cuts Agent Panel memory and CPU on long threads. 1.26 added Pyrefly for Python and WebAssembly stepping in the JavaScript debugger.
◆ Where it's heading
The agent side is now in a tuning phase: recent releases spend more effort on resource use, defaults and small quality gains than on new agent capabilities. Core editor work (languages, debugger, Git Graph) keeps pace alongside it.
◆ Prediction
Expect more agent performance and quality-of-life fixes plus another round of language and Git Graph additions in 1.28.
