What is Appsmith?

Appsmith kills its own AI datasource and puts the AI assistant in the product instead

v2.3 does two things at once: it ends Appsmith AI datasources — no new ones after the upgrade, existing ones dead on September 30, 2026 — and ships a native AI Copilot for Custom Widgets plus Ask AI in the Community Edition. Around that sit ordinary builder increments: a Card widget with a composable body canvas, Button label styling, a shared tabOrder for keyboard navigation, and a configurable HTML lang attribute. The releases before it were dominated by CVE remediation and the MongoDB 7 / Java 25 re-platform in v2.0.

What is FusionAuth?

FusionAuth's feed publishes version numbers; whether they carry news is a coin flip.

FusionAuth releases every four to eight weeks, but the changelog entries are inconsistent: three of the last six carry nothing but an upgrade-guide link, while the ones that do have notes describe substantial standards and security work. The last documented release, 1.67.0, added RFC 8707 resource scoping so tokens issued by OAuth endpoints can be bound to specific resources. Before it, two consecutive releases tightened API key requirements — 1.65.0 for installation-wide endpoints, 1.66.0 extending the same rule to webhooks it had missed.

Appsmith kills its own AI datasource and puts the AI assistant in the product instead

◆ Current state

v2.3 does two things at once: it ends Appsmith AI datasources — no new ones after the upgrade, existing ones dead on September 30, 2026 — and ships a native AI Copilot for Custom Widgets plus Ask AI in the Community Edition. Around that sit ordinary builder increments: a Card widget with a composable body canvas, Button label styling, a shared tabOrder for keyboard navigation, and a configurable HTML lang attribute. The releases before it were dominated by CVE remediation and the MongoDB 7 / Java 25 re-platform in v2.0.

◆ Where it's heading

The AI story is being rebuilt one layer up. Instead of AI reachable as a datasource you wire into a query, it is becoming an assistant embedded in the authoring experience — Ask AI stubs appeared in v2.0, and v2.3 makes it real and gives it to the free tier. Meanwhile the security-fix volume that defined v1.98 through v2.1 has thinned, which suggests the hardening backlog opened by the re-platform is largely worked off and feature capacity is returning.

◆ Prediction

Expect the Copilot surface to widen from Custom Widgets to general app authoring — queries, JS objects, bindings — before the September 30 datasource cutoff makes the old path unusable. The entries do not indicate whether Ask AI in Community Edition stays free once it is past this release.

F2.5

FusionAuth's feed publishes version numbers; whether they carry news is a coin flip.

◆ Current state

FusionAuth releases every four to eight weeks, but the changelog entries are inconsistent: three of the last six carry nothing but an upgrade-guide link, while the ones that do have notes describe substantial standards and security work. The last documented release, 1.67.0, added RFC 8707 resource scoping so tokens issued by OAuth endpoints can be bound to specific resources. Before it, two consecutive releases tightened API key requirements — 1.65.0 for installation-wide endpoints, 1.66.0 extending the same rule to webhooks it had missed.

◆ Where it's heading

Where the notes are readable, the direction is standards conformance and closing security defaults that were too permissive, accepting breaking changes to do it. FusionAuth has been willing to make an enabled identity provider's linking strategy immutable and to require global API keys where tenant keys used to work — changes that break running deployments in exchange for a tighter default. What cannot be read from this feed is where the last two releases fit, because they shipped without notes.

◆ Prediction

The pattern of hardening endpoint-by-endpoint suggests further scope narrowing wherever tenant-level keys still reach installation-level effects. Any read on 1.68.0 and 1.69.0 would be guesswork — the entries carry no content.
