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 Sanity?

Sanity ships across every package at once, and the agent-facing surface moves fastest.

Sanity releases as a fleet: MCP server, Studio, JavaScript client, Media Library and UI all cut versions within days of each other, and the changelog reads as one stream of package releases. The current window is dominated by two lanes — the MCP server steadily gaining tools agents can call, and a round of modernization breakage in the client libraries (ESM-only, Node 22.12 floor). Studio v6.10.0 now bundles the App SDK, so custom Studio tools can call SDK hooks without wiring their own provider.

Firebird maintains three release branches at once and ships the same fixes to all of them

◆ 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.

Sanity
DEVOPS
7.5

Sanity ships across every package at once, and the agent-facing surface moves fastest.

◆ Current state

Sanity releases as a fleet: MCP server, Studio, JavaScript client, Media Library and UI all cut versions within days of each other, and the changelog reads as one stream of package releases. The current window is dominated by two lanes — the MCP server steadily gaining tools agents can call, and a round of modernization breakage in the client libraries (ESM-only, Node 22.12 floor). Studio v6.10.0 now bundles the App SDK, so custom Studio tools can call SDK hooks without wiring their own provider.

◆ Where it's heading

The MCP server is where the capability surface is actually growing — asset upload, schema discovery, CORS management — each release handing agents another operation that previously needed a human in the dashboard. The library work underneath is consolidation: one module system, one supported Node line, fewer dependencies, and now one SDK shared between Studio extensions and standalone apps. Read together, Sanity is narrowing the number of ways to build against it while widening what an agent can do unattended.

◆ Prediction

Expect the MCP tool list to keep absorbing dashboard operations — deploy, dataset and role management are the obvious remaining gaps — and the ESM-only floor to propagate to the packages that have not taken it yet. The releases are per-package, so a single dated entry rarely tells the whole story of a given week.
