+version: 0.3.7
+date: 2026-08-27
+title: Smoother Streaming and Clearer Session Controls
+summary: Long replies now stream without freezing the page, the working indicator and approval panel tell you what is going on, and provider and checkout problems recover on their own.
+githubRelease: https://github.com/Threadlines/threadlines/releases/tag/v0.3.7
+highlights:
+  - title: Streaming replies no longer freeze the page
+    description: Long replies stream at a steady pace instead of arriving in big pauses. Code blocks get syntax color as the text arrives, so you can read along while the agent is still writing.
+    evidence:
+      - c36606aa
+  - title: Working indicator shows what the turn is doing
+    description: Three moving dots next to the status word tell you whether a turn is working, thinking, or sending. Delegated agents stay anchored after a turn settles, and subagent activity no longer flips the main indicator.
+    evidence:
+      - 5b91fa19
+      - 00364ba4
+  - title: Approval panel shows what you are approving
+    description: A pending approval now shows the actual command or tool detail on its own line and names the tool when the request is not a shell command. The action buttons wrap on narrow screens, so the panel fits on a phone.
+    evidence:
+      - c3c585d6
+  - title: Provider status recovers from slow checks
+    description: A slow Claude status check is now a warning that retries on its own instead of blocking the app. Stale warnings clear after a successful check, and the status and connection screens give clearer guidance.
+    evidence:
+      - 33908eb6
+alsoImproved:
+  - description: Switching branches or worktrees from the app is more reliable.
+    evidence:
+      - 145871a9
+  - description: Threads are ordered the same way everywhere (sidebar, chats view, command palette, and thread actions). The separate sidebar sort setting is gone.
+    evidence:
+      - be1043f4
+      - fa0daa62
+  - description: Model labels in the composer stay readable before they overflow, and thread drafts survive switching views.
