     The dict is forwarded to vtsls via `initializationOptions`, `workspace/didChangeConfiguration`,
     and `workspace/configuration` pulls. Enables Yarn PnP setups with `typescript.tsdk` pointing
     at the Yarn-generated SDK.
+  - `SvelteLanguageServer`: Fix diagnostics requests for TypeScript/JavaScript files incorrectly being
+    processed by the Svelte LS instead of the TypeScript LS.
+  - Improve quoting of arguments in shell executions
   - `typescript` / `typescript_vts`: No longer ignore directories named `coverage`. This was intended to skip
     coverage-report output, but matched by bare dirname and so also hid legitimate source directories named
     `coverage` (e.g. `src/routes/coverage/`) from symbol tools. Generated report dirs are already covered by
     gitignore. Fixes #1523.
 
-* Dashboard: 
-  - Fix: Host validation required a local host regardless of the listen address (regression introduced in v1.5.2),
-    preventing remote connections
+* JetBrains:
+  - Add configuration option `jetbrains_launch_command`, allowing Serena to spawn IDE instances automatically
+    upon project activation
+
+* Dashboard:
+  - Make list of trusted hosts configurable, fixing host validation introduced in v1.5.2 allowing only
+    default local hostnames, effectively preventing remote connections
+  - Decouple configuration computation from the agent's task queue by introducing events for agent config/status updates.
+    This allows the dashboard to display the configuration while the project provided at startup is still initialising. #1064
+  - Fix empty executions queue displaying "Loading..."
+  - Tray manager: Add NixOS-support for AppIndicator-based trays (e.g., most Wayland-trays) to the package in flake.nix.
+  - Fix: Wait for the subprocess that opens the browser window, preventing zombie processes #1488

 ## Prompting Strategies
 
 We found that it is often a good idea to spend some time conceptualizing and planning a task
-before actually implementing it, especially for non-trivial task. This helps both in achieving
-better results and in increasing the feeling of control and staying in the loop. You can
-make a detailed plan in one session, where Serena may read a lot of your code to build up the context,
-and then continue with the implementation in another (potentially after creating suitable memories).
-
-## Running Out of Context
-
-For long and complicated tasks, or tasks where Serena has read a lot of content, you
-may come close to the limits of context tokens. In that case, it is often a good idea to continue
-in a new conversation. Serena has a dedicated tool to create a summary of the current state
-of the progress and all relevant info for continuing it. You can request to create this summary and
-write it to a memory. Then, in a new conversation, you can just ask Serena to read the memory and
-continue with the task. In our experience, this worked really well. On the up-side, since in a
-single session there is no summarization involved, Serena does not usually get lost (unlike some
-other agents that summarize under the hood), and it is also instructed to occasionally check whether
-it's on the right track.
-
-Serena instructs the LLM to be economical in general, so the problem of running out of context
-should not occur too often, unless the task is very large or complicated.

 ## Serena and Git Worktrees
 
 [git-worktree](https://git-scm.com/docs/git-worktree) can be an excellent way to parallelize your work. More on this in [Anthropic: Run parallel Claude Code sessions with Git worktrees](https://docs.claude.com/en/docs/claude-code/common-workflows#run-parallel-claude-code-sessions-with-git-worktrees).
 
-When it comes to serena AND git-worktree AND larger projects (that take longer to index), 
-the recommended way is to COPY your `$ORIG_PROJECT/.serena/cache` to `$GIT_WORKTREE/.serena/cache`. 
-Perform [pre-indexing of your project](indexing) to avoid having to re-index per each worktree you create. 
+Be sure to add the `.serena` folder to version control, such that your project-specific settings and memories are available across worktrees.
