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.

What is Zed?

Zed 1.26 adds Pyrefly for Python and debugs WebAssembly from the JavaScript debugger.

Zed 1.26.2 adds Pyrefly as an optional built-in Python language server, an expandable variable tree in debugger hovers and DWARF support so the JavaScript debugger can step through WebAssembly sources. Agent work continues in smaller pieces: ACP configuration defaults now apply only to new conversations, model pickers get better fuzzy search, and thinking controls explain when thinking can't be turned off. The previous week's 1.25 line shrank binaries and gave external ACP agents context compaction.

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

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.

DEVOPS
5.0

Zed 1.26 adds Pyrefly for Python and debugs WebAssembly from the JavaScript debugger.

◆ Current state

Zed 1.26.2 adds Pyrefly as an optional built-in Python language server, an expandable variable tree in debugger hovers and DWARF support so the JavaScript debugger can step through WebAssembly sources. Agent work continues in smaller pieces: ACP configuration defaults now apply only to new conversations, model pickers get better fuzzy search, and thinking controls explain when thinking can't be turned off. The previous week's 1.25 line shrank binaries and gave external ACP agents context compaction.

◆ Where it's heading

Zed is splitting attention between its agent panel, where ACP agents keep gaining the same session handling as Zed's own, and core editor depth in languages and debugging. Weekly stable releases with community-contributed features and quick model additions remain the pattern.

◆ Prediction

Expect 1.27 next week with more ACP session and model-picker work, plus further debugger and language-server additions.
