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 mlr3misc?

The mlr3 utility belt has spent a year rebuilding how errors travel

mlr3misc holds the helper functions the rest of mlr3 is built on — dictionaries, callbacks, assertions, and encapsulate() for running code with its conditions captured. The last six releases are one sustained project on that last piece: returning condition objects instead of strings, respecting .seed and .opts under the evaluate method, supporting parent conditions on Mlr3Error, and short-circuiting when .timeout is zero rather than silently disabling enforcement. A mirai encapsulation method arrived along the way.

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.

The mlr3 utility belt has spent a year rebuilding how errors travel

◆ Current state

mlr3misc holds the helper functions the rest of mlr3 is built on — dictionaries, callbacks, assertions, and encapsulate() for running code with its conditions captured. The last six releases are one sustained project on that last piece: returning condition objects instead of strings, respecting .seed and .opts under the evaluate method, supporting parent conditions on Mlr3Error, and short-circuiting when .timeout is zero rather than silently disabling enforcement. A mirai encapsulation method arrived along the way.

◆ Where it's heading

The direction is making failures inspectable rather than merely reported. Storing conditions as objects lets callers branch on error class, which is why warningf() and stopf() gained a class argument and the mlr3warning and mlr3error classes; removing the msg column from encapsulate logs was the breaking change that followed from committing to that representation. Utility functions also keep migrating inward from other mlr3 packages, as the checkmate operators moved from mlr3pipelines show.

◆ Prediction

With conditions now carrying class and parentage, the natural follow-on is the calling packages using that structure — typed error handling in mlr3 and mlr3tuning rather than further work here.
