What is Appsmith?

Appsmith 2.7 makes its MCP agent ask before deleting widgets and blocks stale edits.

Appsmith v2.7.0, released November 12, mostly extends the embedded MCP server: removing widgets now needs the user's approval, layout updates are refused if the page changed since the agent read it, and agents can build conditional forms, read editor-written JS objects and hide pages. It also adds Table auto height, tightens permissions for custom JS libraries and forking, and applies the restricted-host policy to S3 and DynamoDB datasources. Helm probe defaults and navigateTo behaviour change on upgrade.

What is Bun?

Bun 1.4.4 adds bun fmt, a built-in Prettier-compatible formatter, two weeks after bun check.

Bun now covers formatting as well as type checking: v1.4.4 ships bun fmt, a Prettier-compatible formatter it says is 3-6x faster than oxfmt, and makes bun check 1.4-7.8x faster on large projects. The same release closes 271 issues, migrates Yarn Berry lockfiles, adds install retries with backoff, and cuts Bun.SQL CPU per query by up to 48%.

5.0

Appsmith 2.7 makes its MCP agent ask before deleting widgets and blocks stale edits.

◆ Current state

Appsmith v2.7.0, released November 12, mostly extends the embedded MCP server: removing widgets now needs the user's approval, layout updates are refused if the page changed since the agent read it, and agents can build conditional forms, read editor-written JS objects and hide pages. It also adds Table auto height, tightens permissions for custom JS libraries and forking, and applies the restricted-host policy to S3 and DynamoDB datasources. Helm probe defaults and navigateTo behaviour change on upgrade.

◆ Where it's heading

Since Appsmith AI shut down in September, the MCP server has become the product's AI strategy: each release widens what outside agents can build and adds guardrails on what they can break. Security hardening of permissions and datasources runs alongside in every release.

◆ Prediction

Expect more MCP tools behind user approval and further 2.7.x patches for the Helm probe and navigateTo changes, as followed earlier minor releases.

6.3

Bun 1.4.4 adds bun fmt, a built-in Prettier-compatible formatter, two weeks after bun check.

◆ Current state

Bun now covers formatting as well as type checking: v1.4.4 ships bun fmt, a Prettier-compatible formatter it says is 3-6x faster than oxfmt, and makes bun check 1.4-7.8x faster on large projects. The same release closes 271 issues, migrates Yarn Berry lockfiles, adds install retries with backoff, and cuts Bun.SQL CPU per query by up to 48%.

◆ Where it's heading

After the Rust rewrite in July and bun check in v1.4.3, Bun is absorbing the remaining steps of a TypeScript toolchain one release at a time. Package-manager reliability work (Yarn Berry migration, retries, faster hoisted installs) shows it is also going after teams still on other package managers.

◆ Prediction

Expect a linter or lint mode next to round out the check/fmt pair, and more lockfile migrations aimed at pnpm and Yarn users.
