What is Appsmith?

Appsmith 2.6 starts the move off Temporal, with a real upgrade trap for EE self-hosters.

Appsmith v2.6.0 moves workflows to a new engine, and EE users must finish Temporal runs on v2.5.1 first; pending approvals from the old engine can stop the whole server from starting. It also fixes the Node.js Brotli vulnerability CVE-2026-111497, requires static Redis command names, tightens workspace and page-read permissions, and adds isNull, anyOf and like options to MCP structured SQL filters.

What is ASP.NET Core?

ASP.NET Core's October patch day hardens HTTP/2 on 8.0 and 9.0 while .NET 11 waits for GA.

ASP.NET Core services the 8.0, 9.0 and 10.0 branches while .NET 11 sits at RC2. The October 13 patch day shipped 9.0.21 and 8.0.32 with the same fix set: HTTP/2 now rejects newline characters in trailers and the dynamic HPACK table, HTTP/3 abort locking is corrected, and the SignalR Java client no longer hangs when a response read fails. The last 11.0 tag removed DeviceBoundSessions rather than adding anything.

Appsmith vs ASP.NET Core: editorial side-by-side

Appsmith
DEVOPS
5.0

Appsmith 2.6 starts the move off Temporal, with a real upgrade trap for EE self-hosters.

◆ Current state

Appsmith v2.6.0 moves workflows to a new engine, and EE users must finish Temporal runs on v2.5.1 first; pending approvals from the old engine can stop the whole server from starting. It also fixes the Node.js Brotli vulnerability CVE-2026-111497, requires static Redis command names, tightens workspace and page-read permissions, and adds isNull, anyOf and like options to MCP structured SQL filters.

◆ Where it's heading

Appsmith is shifting from bundling its own AI to being a governed target for external AI clients, and each release widens MCP a little while narrowing what it can reach. Self-hosters keep taking on upgrade work: first docker.env, now a workflow engine migration. Browser telemetry dropping for published-app users fits the same tightening.

◆ Prediction

The next release will likely extend MCP tool coverage again and bring follow-ups for engine transition problems; the entries don't give a date for dropping the MCP beta label.

A5.0

ASP.NET Core's October patch day hardens HTTP/2 on 8.0 and 9.0 while .NET 11 waits for GA.

◆ Current state

ASP.NET Core services the 8.0, 9.0 and 10.0 branches while .NET 11 sits at RC2. The October 13 patch day shipped 9.0.21 and 8.0.32 with the same fix set: HTTP/2 now rejects newline characters in trailers and the dynamic HPACK table, HTTP/3 abort locking is corrected, and the SignalR Java client no longer hangs when a response read fails. The last 11.0 tag removed DeviceBoundSessions rather than adding anything.

◆ Where it's heading

Servicing work is now mostly protocol hardening and dependency hygiene, applied identically across branches on a shared patch day. The .NET 11 line is in scope-cutting mode, which points to a GA build with fewer features than the previews carried. MCP library bumps in 10.0 patch releases show agent tooling moving on a faster track than the major-version train.

◆ Prediction

The next tags should be .NET 11 GA and a 10.0 patch carrying the same HTTP/2 hardening. The entries don't show whether DeviceBoundSessions returns after GA.
