Changelog

1.0.0-preview.10

July 23, 2026 · Current preview

Preview 10 restores reliable startup with modern MCP clients that check for a newer discovery flow before beginning the supported initialization exchange.

• Clients such as Antigravity CLI can probe for server discovery before sending the normal MCP initialization request without losing the Atlas Scout connection.
• Scout answers the unsupported probe with the standard method-not-found response, then keeps the same connection ready for ordinary initialization and tool use.
• The compatibility behavior is identical for direct atlas-scout mcp sessions and sessions using the local atlas-scoutd daemon.
• No host configuration change is required after upgrading and starting a new MCP session.
• This is a connection-startup compatibility repair, not support for stateless MCP, Streamable HTTP, or the server/discover method itself.

1.0.0-preview.9

July 22, 2026 · Previous public preview

Preview 9 makes workspace moves and copies recover automatically without risking reuse of an index that belongs to the old location.

• When a workspace arrives at a new canonical path with its .atlas directory, Scout now preserves the old generated cache and creates a clean index for the new location.
• MCP initialization can continue without asking the user to find and delete stale index files manually.
• Scout never rewrites or opens the old SQLite and write-ahead-log state under the new identity, avoiding conflict with a process that may still use the original workspace.
• Diagnostics report preserved relocation archives so they can be inspected and removed later as ordinary ignored generated data.
• Invalid identity data, unsafe filesystem shapes, failed preservation, and explicit external-cache collisions still stop with an honest error instead of attempting a risky recovery.
• The Preview 8 number belonged to a rejected, unpromoted candidate. Preview 9 carries the same runtime repair after its cross-platform acceptance fixtures were made portable and passed on all four targets.

1.0.0-preview.7

July 22, 2026 · Previous public preview

Preview 7 makes multi-million-symbol repositories dramatically faster to index and explore while preserving Scout’s conservative treatment of ambiguous code.

• Exact symbol searches now stay interactive on very large repositories instead of repeatedly scanning the entire symbol map.
• Path, language, and symbol-kind constraints are applied early, so common or overloaded names resolve to the requested file more reliably.
• Broad discovery retains useful CamelCase, snake_case, acronym, and qualified-name matches while doing substantially less work.
• JavaScript and TypeScript cross-file relationship indexing now narrows plausible targets before applying the same precision-first acceptance rules; ambiguous matches remain unresolved rather than guessed.
• The release adds regression coverage for scoped names, broad identifier discovery, and large-project relationship equivalence.
• Locked Firefox and Linux benchmarks confirm the large-repository gains, preserved semantic projections, and the indexing and storage costs that come with the faster retrieval path.

1.0.0-preview.6

July 21, 2026 · Previous preview

Preview 6 improves how Scout follows imported code, rendered components, likely tests, and shared workspace activity.

• JavaScript, TypeScript, JSX, and TSX imports now contribute stronger call and component-usage evidence, including aliases and common project-root path shortcuts.
• Reference queries can target an exact symbol within a known file and can find the components that render a JSX or TSX component.
• Edit-impact results now include a small, clearly non-exhaustive shortlist of tests that are likely to matter.
• Source coordinates are more consistent, and health reports now explain when another Scout process is updating the shared index while reads remain available.
• Unrelated functions that happen to share a name are less likely to appear as false relationships.

1.0.0-preview.5

July 20, 2026 · Claude Code integration and smaller responses

Preview 5 makes Atlas Scout a first-class Claude Code integration and reduces the amount of context needed for common navigation work.

• Release archives now include a Claude Code plugin that makes Scout available to the main session and delegated subagents.
• Optional workflow guidance and compact task recipes help agents choose the right structural tool without preventing normal reads, searches, Git, tests, or terminal work.
• Search, outline, and broad task-orientation results start with smaller defaults and can still be expanded when deeper evidence is needed.
• Search ranking better separates useful identifiers from incidental path matches.
• Empty reference results describe their coverage instead of implying that a symbol is definitely unused.

1.0.0-preview.4

July 19, 2026 · Better Go and React understanding

Preview 4 expands relationship evidence for Go and React while making host discovery and normal responses more dependable.

• Go interface implementations can be discovered when the evidence is unambiguous.
• Rendered JSX and TSX components participate in references and change-impact analysis instead of appearing unused.
• File outlines are concise by default, with deeper declarations available on request.
• Codex, Claude Code, and generic MCP hosts receive clearer guidance for finding Scout without losing access to ordinary repository tools.
• Index upgrades, persisted health, stale identifiers, and ambiguous relationships now fail or recover more honestly.

1.0.0-preview.3

July 17, 2026 · Clearer setup and diagnostics

Preview 3 delivers the setup, licensing, and diagnostic improvements prepared for the unpublished Preview 2 candidate.

• Indexing and diagnostics now use readable terminal output by default, with JSON and legacy machine-readable forms available for automation.
• Device activation gives clearer labels, safer credential-store checks, and more useful recovery instructions when local storage fails.
• Host setup distinguishes global registrations from project-pinned configurations and reminds users to reconnect after configuration changes.
• Generated database size and bounded indexing progress are visible in the CLI.

1.0.0-preview.1

July 16, 2026 · First public preview

Preview 1 established Atlas Scout as a local, multi-language code map with permanent Free navigation and optional deeper Pro analysis.

• Fourteen bounded, read-only MCP tools cover symbol discovery, references, structural paths, architecture, task orientation, and edit impact.
• Each workspace gets one shared, gitignored index that can be reused by agents, the CLI, and the optional local daemon.
• Free works without an account or network connection; evaluations and paid access use locally verified leases with non-destructive fallback to Free.
• Activation, offline status, refresh, deactivation, and device management are available from the CLI with native credential storage on supported platforms.
• Discovery became more relevant and more compact, with bounded source ranges, stable pagination, explicit health, and honest treatment of unresolved evidence.
• The release was validated against the complete Firefox checkout and shipped with signed checksums, provenance, and third-party notices.
