What changed, what you can download, and what to check before updating.
Releases & access
Available downloads
0.1.0-rc20 Windows x64 installer and 0.1.0-rc20 Linux x64 DEB/AppImage (qualified on Ubuntu 22.04); 0.1.0-rc20 macOS 15+ Apple Silicon DMG/ZIP. All are unsigned. Intel Macs are unsupported. The download panel checks current availability for each platform.
Who can download
Sign in with an internal, Pro or Enterprise workspace to download. A free account does not include access; contact support to request it.
License by edition
Pre-release software terms and bundled third-party notices apply. See the licensing notice for the preserved prior grants and current scope.
Before you update
Use the entitled download panel for updates. Save and back up your .csp sessions before upgrading. Keep the previous installer for recovery; automatic background updates are not offered by this preview.
Curated from retained source changelogs, GitHub release records and platform publication receipts. Windows, Apple Silicon macOS and Ubuntu Linux have separately qualified and published rc20 packages. Older entries describe their recorded scope and do not offer historical downloads. Missing early release notes are not reconstructed from guesses.
0.1.0-rc20 — Saved canvas and adjustable Apple Silicon workspace
macOS 15+ · arm64 DMG and ZIP
Added: Resize or hide the left, right and Results panels; choose Follow OS, Light or Dark appearance; browse a searchable, categorized node and table library.
Added: Find workflow nodes, use directional edges and the navigation overview, and save node arrangement and view with the session.
Fixed: The cumulative release includes complete session/result saves from rc18/rc19, installed-path-safe starter templates, connection-drag repairs and measured automatic layout.
Upgrade notes & limitations
Unsigned and unnotarized Apple Silicon preview. Verify the displayed SHA-256 and, if you trust this build, use macOS Privacy & Security → Open Anyway. Intel Macs are unsupported. Back up .csp sessions before upgrading. First-run assisted runtime setup needs Internet access; local analysis can then run offline. A clean-machine or general clinical-oracle qualification is not claimed.
Native Apple Silicon macOS rc20 artifact and installed-product qualification, exact-byte private-bucket promotion and rollback receipt, 30 September 2026.
0.1.0-rc20 — Saved canvas and adjustable workspace on Ubuntu
Ubuntu Linux x64 · DEB and AppImage
Added: Resize or hide the left, right and Results panels; choose Follow OS, Light or Dark appearance; browse searchable node and table libraries.
Added: Find workflow nodes, use the upper-right navigation overview, and save node layout and view with the session.
Fixed: Starter templates load from the installed package, connection gestures avoid abandoned edges, and the cumulative rc18/rc19 repairs preserve complete results and sessions.
Upgrade notes & limitations
Unsigned x64 preview qualified on Ubuntu 22.04. Verify SHA-256 before installing the DEB or running the AppImage, and back up .csp sessions before upgrading. Debian/Ubuntu assisted repair uses apt-get and pkexec; other systems use the manual setup commands. Broader distribution and clinical-oracle qualification is not implied. Other platforms have their own native qualification records.
Native Ubuntu rc20 DEB/AppImage qualification and exact-byte private-storage promotion receipt, 30 September 2026; Windows and macOS retain their separate publication records.
0.1.0-rc20 — Saved canvas and adjustable workspace
Windows x64 · NSIS installer
Added: Resize or hide the left, right and Results panels; choose Follow OS, Light or Dark appearance; browse a searchable, categorized node and table library.
Added: Find workflow nodes, read directional edges and the upper-right navigation overview, and save node layout and view with the session.
Fixed: Starter templates load from the installed package; connection drags avoid selection and abandoned lines; measured layout reduces overlaps. The cumulative release also includes the rc18/rc19 session and output persistence repairs.
Upgrade notes & limitations
Unsigned Windows preview: verify the displayed SHA-256 before the SmartScreen flow. Back up .csp sessions before upgrading. Other platforms use their separately qualified and published packages.
Windows rc20 installed-product qualification and private-bucket promotion receipt, 30 September 2026; Mac and Linux rc20 are recorded separately.
0.1.0-rc17 — Linux assisted setup and upgrade recovery
Linux x64 · DEB and AppImage
Added: Repair automatically can set up Python and OpenJDK 17 on Debian/Ubuntu through apt and the desktop authorization dialog; the app never receives your administrator password.
Fixed: Rename upgrades reuse populated legacy profiles in place, preserving virtual-environment paths. The setup dialog remains usable at the minimum window size.
Upgrade notes & limitations
Unsigned preview. Verify the selected package hash. Systems without apt-get and pkexec use the manual commands shown in the setup window. Broad Linux distribution and clinical-oracle qualification is not implied.
Linux publication receipt and active platform manifest checked 26 September 2026; source qualified separately from the earlier Mac and Windows builds.
Fixed: Startup-only Python dependency failures now appear in Environment Setup with a Repair automatically action. After repair, Retry Backend rechecks the managed environment.
Changed: Live product names, CLI help and preferences use CohortDAG, with legacy discovery paths retained for upgrades.
Upgrade notes & limitations
Unsigned installer; verify SHA-256 before following Windows SmartScreen guidance. The recorded native check covered an installed-app dependency repair and real Spark startup, not every clinical analysis.
Windows rc17 installer qualification and exact-byte publication receipt; active manifest checked 26 September 2026.
0.1.0-rc17 — First CohortDAG Apple Silicon preview
macOS 15+ · arm64 DMG and ZIP
Added: Apple Silicon packages use assisted, per-user runtime setup from pinned upstream builds. The entitled website supplies the installer and verification hash.
Changed: Update discovery leads to the authenticated product page. The inaccessible generic update feed was removed.
Upgrade notes & limitations
Unsigned and unnotarized; verify the hash and follow the platform's Open Anyway guidance. Intel Macs are unsupported. Clean-machine, clinical-oracle, performance and lifecycle checks remain incomplete. Later Windows/Linux repair changes are not claimed for this earlier Mac build.
Mac artifact/publication checklist and owner-reported acceptance on 25 September; active manifest checked 26 September 2026.
Changed: The CohortDAG-named Windows installer was distributed through the entitled website. Its previous active manifest is retained in the rollback record.
Upgrade notes & limitations
Superseded by rc17. No separate rc16 heading survives in the source changelog; this entry records the verified Windows publication without inventing a feature list or other platform release dates.
Retained Windows rollback manifest: version rc16, published 17 September 2026; read during the 26 September audit.
Fixed: Corrected sc:// Spark Connect routing and connection-aware execution. Worked demo sessions and their sample dataset now travel with the installer.
Upgrade notes & limitations
Remote Spark Connect environments still need their compatible client dependencies and reachable data.
Retained rc14 changelog and GitHub prerelease publication record.
Fixed: Consent requests bring attention to the app; agent instructions preserve results in the reviewable session and teach memory-aware pipeline planning. Default Spark driver memory scales with available RAM.
Upgrade notes & limitations
A source changelog date does not establish a downloadable package for every platform.
Retained source changelog and release commit cb6e751.
Added: Agents can propose nodes and edges to the open canvas through push_dag; a person must approve. The bridge supports one pending request, undo and a kill switch.
Upgrade notes & limitations
Agents should save results into the same .csp session and hand that file back for human review.
Retained rc9 changelog and version tag; bridge protocol 3 and 18-tool MCP contract.
