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 Stirling-PDF?

Stirling PDF plans to drop LibreOffice for its own converter within two weeks

Stirling PDF 3.0 in late September added the PDF Processor for bulk jobs, optional AI and free OAuth SSO. Releases since have come about every two weeks: group signing by default in 3.1.0, a Page Editor in 3.2.0, viewer and annotation work in 3.2.x. 3.3.0 lets users pick the beta Stirling Office Convert in many more tools and adds Windows ARM64, lighter mobile scanning and caching.

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.

S5.0

Stirling PDF plans to drop LibreOffice for its own converter within two weeks

◆ Current state

Stirling PDF 3.0 in late September added the PDF Processor for bulk jobs, optional AI and free OAuth SSO. Releases since have come about every two weeks: group signing by default in 3.1.0, a Page Editor in 3.2.0, viewer and annotation work in 3.2.x. 3.3.0 lets users pick the beta Stirling Office Convert in many more tools and adds Windows ARM64, lighter mobile scanning and caching.

◆ Where it's heading

The project is replacing third-party dependencies with its own components. 3.3.0 says Office Convert should become the default next week and LibreOffice should be removed the week after, which would shrink the install and change conversion results for every user.

◆ Prediction

Expect Office Convert to become the default converter in the next release, then LibreOffice removed, as 3.3.0's notes lay out. Conversion bug reports will decide whether that schedule holds.
