++ Here are the highlights of the v1.7.0 release: +
+
+ Grok Support.
+ Serena now supports Grok Build as a client, including the grok context, setup via the CLI,
+ and hooks (serena-hooks --client=grok) with Grok-native PreToolUse allow/deny output.
+
+ Expanded Language Support.
+ New language servers: Gleam (via gleam lsp), Nextflow (official language server, JAR downloaded
+ automatically, Java 17+ required), Deno (experimental; understands npm:/jsr:/https:
+ imports and the Deno.* globals, must be selected explicitly), and
+ python_basedpyright as an alternative Python language server.
+ The managed Kotlin language server was updated, now including Windows ARM64 builds.
+
+ Renamed Project Setting.
+ The languages key in project configurations is now called language_servers,
+ which better reflects its actual semantics. Existing configurations are migrated automatically.
+
+ Security Hardening. + The project server and the dashboard tray manager now configure trusted hosts (local hosts only) when + listening on localhost, and prompt templating runs in a sandboxed environment, preventing attackers from + using custom prompts to execute commands in an uncontrolled manner. +
+
+ Prompts & Templating.
+ Initial project prompts and project-specific newly activated modes can now use templating, and the new
+ embed_memory function inlines a memory's contents into a prompt template.
+ Sub-prompts are enclosed in XML-like tags to make scopes explicit.
+
+ More Liberal Handling of Ignored Paths.
+ Tools that explicitly target a single file (create_text_file, read_file,
+ replace_content) no longer consider ignored paths at all – when a path is explicitly
+ accessed, the agent is assumed to have a good reason for doing so.
+ Tools that traverse a subtree (list_dir, find_file, search_for_pattern)
+ now uniformly offer a skip_ignored_files option.
+
+ Better Diagnosability.
+ Project activation errors are now reported to the client in Serena's system prompt instead of being visible
+ only in the log, get_current_config includes the language server status, and
+ project health-check exits with a non-zero code when the check fails.
+
+ Robustness & Fixes.
+ A multitude of fixes across the board, including Scala/Metals (build import and monorepos with several build
+ roots), TypeScript (incomplete reference results on large projects), Erlang (name paths for functions),
+ F#, Nix, Ansible, Rust memory usage, orphaned language server processes on Linux,
+ race conditions in the project server, blocked tool call timeouts, and the dashboard,
+ which now uses the tray_manager interface by default on macOS.
+
+ See our change log for the full list of changes. +
+
+ Update Now.
+ If you are using the uv tool installation of Serena, upgrade as follows:
