Changelog

This page tracks user-facing changes to Cosine Cloud — the dashboard and the backend services that power it.

Cloud update — 2026-08-10

Tag: 26.08.10-548.

New Features

Automated CI-fix workflows

Configurable signup methods

The sign-up page now loads the authentication methods enabled for the deployment and only presents valid options. This gives managed and on-premise deployments tighter control over how users can create accounts, with clearer feedback when a method is unavailable.

DeepSeek V4 Flash

DeepSeek V4 Flash is now available in the Cloud model selector.

Fixes

• Removed the obsolete custom file-mention flow from the dashboard composer, avoiding unsupported attachment suggestions.
• Improved configuration of models used by managed evaluation experiments.

Cloud update — 2026-08-03

Tag: 26.08.03-547.

New Features

Kimi K3

Kimi K3 is now available through Cosine Cloud.

Invoice history

• Updated model aliases and pricing metadata so usage is attributed and charged against the correct model.
• Simplified token-credit accounting to make usage totals more consistent.

Cloud update — 2026-07-21

Tag: 26.07.21-545.

New Features

Account verification

New-account creation now includes an additional verification step to reduce automated and abusive signups.

Improved mobile task experience

The Cloud task interface received a dedicated mobile-layout pass, making active sessions and their controls easier to use on smaller screens.

Clearer planning transitions

The task timeline now shows when an agent is busy switching into planning mode, and planning questions and responses are handled more consistently.

Fixes

• Preserved the active task side panel when refreshing the page.
• Fixed concurrent questionnaire requests and improved the rendering and lifecycle of questionnaire tool calls.
• Fixed Cloud tasks using an incorrect inference URL.
• Fixed signed artifact links that could fail to open.
• Restored the models used to generate task titles and retrieve memories.
• Hid internal planning messages that were not intended to appear in the user-visible timeline.
• Standardised task-pane headers for a more consistent layout.
• Improved inference routing and error handling for Cloud and on-premise deployments.

Cloud update — 2026-07-13

Tags: 26.07.13-543, 26.07.13-544.

New Features

Better task failure feedback

Cloud tasks now surface clearer, more actionable errors when a run cannot start or continue, rather than leaving the task in an ambiguous state.

Large remote diffs

Remote runtimes now handle slower and much larger diff results more reliably, making substantial agent changes easier to review from the dashboard.

Fixes

• Fixed invited users returning to the dashboard with stale team information; the newly joined team now appears without requiring another reload or sign-in.
• Fixed race conditions affecting live task state and event delivery.
• Prevented agents from leaving planning mode prematurely.
• Improved the prompt used when an agent finishes planning, producing a cleaner transition back into execution.
• Corrected completion detection for streamed model responses that send their terminal event in data-only frames.
• Updated model catalogue labels so model names are clearer and more consistent.
• Replaced the previous message-list virtualisation path with a more reliable conversation scroller.

Cloud update — 2026-07-01

Tag: 26.07.01-542.

New Features

Claude Sonnet 5

Claude Sonnet 5 is now available across supported Cloud surfaces.

Claude Haiku 4.5 and GLM 5.2

• Stabilised session-history item identifiers, preventing duplicate or shifting rows when a task is rehydrated.
• Fixed raw provider token counts incorrectly draining Cosine Credits.
• Scoped prompt-cache keys to individual conversations, improving cache reuse within each conversation.
• Fixed Anthropic context compaction failures during long-running tasks.
• Improved recovery when hydrating interrupted sessions by discarding stale encrypted reasoning data and rewinding to the last valid checkpoint before replay.
• Fixed early Sonnet 5 routing and configuration issues discovered during rollout.

Cloud update — 2026-06-26

Tags: 26.06.26-540, 26.06.26-541.

New Features

Cleaner task timelines

Task timelines now deduplicate repeated events and compact related activity, making long-running sessions easier to scan without losing important progress updates.

Environment lifecycle terminal overlay

The terminal now shows a dedicated overlay while a cloud environment is starting, stopping, sleeping, waking, or reconnecting. This makes it clearer why the terminal is temporarily unavailable instead of leaving an apparently unresponsive panel.

Fixes

• Polished several awkward dashboard layouts and interaction states.
• Restored the intended ownership and handling of the install step in onboarding.

Cloud update — 2026-06-25

Tag: 26.06.25-539.

New Features

Better filtering and identification in analytics

Analytics graphs now support fuzzier matching and expose user email details where appropriate, making it easier to find and distinguish team members in usage data.

Refreshed Cloud branding

Dashboard favicons now use the redesigned blue visual system.

Fixes

• Fixed authorization for Kimi models and their aliases so eligible users can select and run them reliably.

Tags: 26.06.24-537, 26.06.24-538.

New Features

• Improved model failover handling by preserving provider state with encrypted model content, preventing valid responses from being rejected or incorrectly retried through another provider.
• Corrected team attribution on model requests so access controls and usage reporting are applied to the right team.
• Improved the accuracy and efficiency of usage analytics events while suppressing duplicate telemetry.

Cloud update — 2026-06-22

Tags: 26.06.22-534, 26.06.22-535.

Fixes

• Fixed an omitted provisioning path that could prevent newly created free-trial teams from receiving their Cloud environment automatically.
• Corrected partial user-data selection in task events and data jobs, improving the reliability of task activity and downstream reporting.

Cloud update — 2026-06-18

Tag: 26.06.18-533.

New Features

Kimi K2.7 Code

Kimi K2.7 Code is now available as a selectable coding model in Cloud.

Skippable GitHub setup

New users can now skip GitHub connection during onboarding and continue into Cloud, rather than being blocked when they are not ready to connect a repository.

Active quota-exhaustion handling

When a team runs out of quota, Cloud now detects the condition explicitly and presents an actionable state instead of allowing requests to repeatedly fail or appear stuck.

Fixes

• Improved token accounting so usage and remaining allowance are calculated more accurately.
• Fixed several bring-your-own-key setup and provider-selection issues.
• Improved the reliability of dashboard authentication buttons during redirects and slow network responses.
• Fixed team controls entering an infinite autosave loop after certain settings changes.
• Improved dialog responsiveness, keyboard focus, and focus restoration for more reliable mouse and keyboard interaction.

Fable 5 preview

Fable 5 was temporarily added to the available model set for early access.

Fixes

• Fixed several issues in the new onboarding flow, including incorrect completion prompts and inconsistent step transitions.
• Legacy billing customers no longer see a misleading “Finish Onboarding” indicator.
• Improved token-credit settlement during subscription renewals and churn so balances carry forward or expire more accurately.
• Corrected smaller billing display and plan-selection inconsistencies.
• Updated Anthropic usage pricing to account for prompt-cache creation, improving the accuracy of reported model costs.
• Relocated Instant Sites documentation into the CLI section so links from Cloud point to the current guide.

Cloud update — 2026-06-07

Tag: 26.06.07-531.

New Features

Refreshed login experience

The login flow now uses the redesigned blue visual system, bringing authentication screens in line with the rest of the Cloud dashboard.

Fixes

• Lumen requests that return a provider-level 404 now trigger failover instead of ending the session immediately.
• Fixed the default prompt-cache key used by Responses-based models, improving cache reuse and reducing avoidable repeated input processing.
• Applied the latest blue-system polish across additional dashboard surfaces.
• Improved proxy handling for model requests.

Cloud update — 2026-06-03

Tags: 26.06.03-529, 26.06.03-530.

New Features

Redesigned colour system

Cloud now uses a refreshed blue colour system across dashboard navigation, controls, tooltips, login-related surfaces, and agent modes. Mode colours are easier to distinguish while remaining consistent with Desktop and shared components.

More model choices

Claude Opus 4.8 and Mistral Large are now available to eligible Cloud users. GPT-5.5 also gains an extra-high reasoning option for supported configurations.

Linkable sidebar navigation

Shared sidebar items can now behave as standard links, improving navigation behaviour such as opening destinations in a new tab and preserving expected browser interactions.

Fixes

• Fixed cloud sessions remaining stuck after completion when background memory events arrived after the main task had finished.
• Background memory activity is now kept out of the user-facing task state, preventing completed runs from appearing active again.
• Improved graceful environment shutdown and pod deletion handling so stopped or recycled environments transition cleanly.
• Fixed several model-selector and chat-model configuration issues.
• Corrected token handling for CLI-authenticated Cloud sessions.
• Refined model and onboarding copy, tooltips, and smaller dashboard interactions.

Cloud update — 2026-05-05

Tag: 26.05.05-519.

New Features

New model picker

The model picker has been redesigned to make browsing and selecting models clearer across chat surfaces.

Resizable subagent details

The subagents panel now has a draggable, resizable detail view, making it easier to inspect parallel work while keeping the main timeline visible. Failure states have also been improved.

More secure dashboard authentication

Dashboard authentication now uses an HttpOnly cookie handoff when redirecting through Vercel, reducing exposure of authentication credentials in the browser.

Raw token usage charts

Administrative usage views now include raw token charts for more detailed consumption analysis.

Fixes

• Fixed download controls for generated files and artifacts.
• Fixed custom environment configuration issues across the environment setup interface.
• Fixed height and layout bugs across dashboard panels.
• Extended dark-mode styling across remaining top-level dashboard surfaces.
• Fixed remote task creation from Desktop-backed flows.

Tag: 26.04.29-518.

New Features

WorkOS SSO

WorkOS-based single sign-on is now available behind a feature flag for teams preparing an enterprise SSO rollout.

Clearer browser tab titles

Task pages now set more useful browser tab titles, making active tasks easier to identify when several tabs are open.

Fixes

• Fixed duplicate nudges being submitted from the chat composer.
• Fixed quarantined analytics rows so affected usage data can be processed correctly.
• Improved the email experience with refreshed templates and presentation.

Cloud update — 2026-04-28

Tag: 26.04.28-517.

New Features

Branch details and controls on tasks

A shared branch menu now exposes task branch information consistently across the Cloud UI, with the required branch data supplied by the task API.

Tasks complete when their PR is merged

Cloud tasks are now marked complete automatically when their associated GitHub pull request is merged.

Email magic-link login

You can now sign in through a Firebase email magic link as an alternative to existing authentication methods.

Consistent custom environment setup

Custom environment controls have been brought into alignment across Cloud surfaces, making environment creation and editing more predictable.

Fixes

• Fixed the initial My tasks filter so the task list opens with the expected results.
• Improved session startup and chat banner behaviour, reducing unnecessary loading states while a remote session connects.
• Fixed long task text overflowing the Orchestrator detail panel.
• Fixed mobile and iOS layouts across additional dashboard screens.
• Fixed iOS production builds connecting to the wrong API environment.
• Fixed local authentication callbacks failing to return to the initiating application.

Cloud update — 2026-04-25

Tag: 26.04.25-516.

New Features

GPT-5.5 across Cosine

GPT-5.5 support is now available consistently across Cosine applications.

Red Team page improvements

The Red Team page has received a visual polish pass and now adapts more cleanly to mobile screen sizes.

Consistent task timelines

The dashboard now uses the shared timeline components used by other Cosine surfaces, keeping task events and tool activity visually consistent across products.

Fixes

• Fixed several issues in the dashboard diff panel, improving review of changes across larger pull requests.
• Fixed dropdowns in the dashboard greeting appearing behind surrounding interface elements.

Cloud update — 2026-04-24

Tag: 26.04.24-515.

New Features

LLM-generated PR titles and descriptions

Taskv3-created pull requests now get an LLM-generated title and description that actually explains what changed, instead of a mechanical dump of branch and commit metadata. The technical details (branches, commits, files) are preserved in a clearly-marked managed section below the description, and subsequent pushes update that section in-place rather than appending a new block each time.

Shared tool-call UI across surfaces

The dashboard chat timeline now renders tool calls using the same component as the Desktop app, so tool chains look and behave consistently no matter which surface you’re using.

Fixes

• Fixed invited users being bounced into onboarding on first login — accepting an invite now correctly places you on your inviting team instead of asking you to create one from scratch.
• Restored analytics tracking for taskv3 flows. Event reporting (task_started, task_succeeded, task_failed, create_task, etc.) had been silently dropped for V3 tasks, skewing activation metrics and breaking downstream pipelines — V3 task events now emit again with full user attribution.
• Fixed the model selector popover rendering behind the + menu in the chat composer.
• Reverted an in-flight GPT 5.5 configuration change that was causing model-selection regressions.
• Polished the pull-request review panel copy across the external PR, reviews sidebar, merge, and navigation components.

Cloud update — 2026-04-23

Tags: 26.04.23-513, 26.04.23-514.

New Features

Live context compaction indicator

The dashboard task timeline now shows a live compaction indicator while the agent is compacting context, with an animated loader and progress text, and collapses to a single summary pill when compaction finishes. No more frozen-looking UI while a long session is compacting down.

Deployment cards in the chat timeline

When the agent calls deploy_instant_site, the chat timeline now renders a dedicated deployment card with a clickable preview URL instead of a raw tool-call row. Works for both live sessions and hydrated past sessions.

Fixes

• Fixed a regression that prevented the API worker booting cleanly after the previous deploy — environment provisioning and remote session startup now recover reliably.
• Fixed the artifact card failing to load for completed remote sessions. Addressed an S3 key mismatch, artifact-ID confusion between the local dedup key and the DB UUID, and a filename wiring bug that pointed at the source file instead of the uploaded .html artifact. Remote-runtime data:text/html artifacts are also now retained properly.
• Hardened URL validation in the deployment card and chat markdown so only http: and https: URLs are clickable, blocking javascript: and data: scheme XSS vectors.

Cloud update — 2026-04-22

Tags: 26.04.22-511, 26.04.22-512.

New Features

Desktop colour redesign in the dashboard

The dashboard picked up the Desktop app’s redesigned colour system, so colour treatment is now consistent between dashboard pages, the Desktop app, and the CLI.

Document file uploads

You can now upload document files (PDFs, plans, markdown, and similar) as task attachments from the dashboard, not just images.

Mobile layouts (iOS polish)

Further polish on the mobile dashboard, especially iOS Safari: the homepage, chat panel, and session viewer now render correctly on notch devices, and the Plus button for creating tasks is reachable with one thumb.

Todo progress drawer across surfaces

The Todo progress drawer on the task page now matches the Desktop app visually and propagates the agent’s live todo status into the header strip.

Fixes

• Fixed diff view rendering issues in the pull-request panel when the PR spans many files.
• Fixed several dark-mode bugs where component backgrounds were washed out.
• Reworked websocket connection handling for more reliable reconnect behaviour after a network blip or Vercel cold start.
• Improved pod lifecycle event typing so the connection indicator correctly reflects pods that were recycled mid-session.

Cloud update — 2026-04-21

Tag: 26.04.21-510.

New Features

Cloud session hydration

Opening a past cloud session in the dashboard now rehydrates the full session UI — timeline, tool calls, artifact cards, and panel state — rather than replaying as plain text. Reopening an old task looks identical to viewing a live one.

Data pipeline extensions

Two large landings of the internal data pipeline (feat: more data pipeline, feat: even more data pipeline) power additional checks and telemetry around cloud runs, producing better insights and more accurate usage reporting in Insights.

Mobile homepage

The dashboard homepage has a dedicated mobile layout with a native-feeling Plus button for creating new tasks.

Fixes

• Fixed environment size selection and resource limits so the control you pick in the environment wizard actually flows through to the Kubernetes resource specs at runtime.
• Pentest remediation round 2: patched outdated JavaScript libraries and TLS vulnerabilities flagged in the external pentest.

Cloud update — 2026-04-20

Tag: 26.04.20 (delivered as part of the 510 rollout window).

New Features

Todo progress drawer

A new Todo progress drawer surfaces the agent’s live todo list directly inside the task page.

PR review panel improvements

The pull-request panel on taskv3 now has dedicated design for the PR review flow, including better layout for feedback, approvals, and diffs.

Fixes

• Fixed merge conflict resolution working even when the user hasn’t connected a personal GitHub account.
• Fixed the initial-prompt attachment path so attachments attached before a session starts are sent with the message.
• Pentest remediation round 1: largest vulnerabilities addressed.

Cloud update — 2026-04-17

Tags: 26.04.17-508, 26.04.17-509.

New Features

Insights discoverability

The Insights surface is now promoted into the main user navigation so teams can get to the team-wide usage analytics directly from the sidebar instead of through a nested menu.

iOS layout fixes

A follow-up iOS polish pass covering the task list, task page header, and settings screens.

Support surface

Added a dedicated support entry point accessible from the dashboard shell.

Fixes

• Smaller UI polish rollup (small ui fixes).
• Fixed a handful of T-Systems-specific patches requested for on-prem deployments.
• Corrected docs links that pointed at the old documentation URL structure.

Cloud update — 2026-04-16

Tags: 26.04.16-506, 26.04.16-507.

New Features

Background CLI auth handshake during onboarding

New CLI users who sign in through the dashboard now get a background auth handshake initiated during onboarding, so switching to the CLI after finishing onboarding skips the login step.

Enhanced onboarding for new CLI users

The onboarding flow for first-time CLI users has been polished — clearer copy, better step sequencing, and guided install steps for the CLI and Desktop app.

Claude Opus 4.7

Claude Opus 4.7 is selectable in the dashboard model picker, matching the CLI and Desktop.

Generated branch names on new task creation

New tasks created from the dashboard now get a descriptive branch name derived from the prompt, rather than a random or numeric branch name.

Fixes

• Fixed the team token budget link in the model selector pointing at the wrong page.
• Fixed duplicate assistant messages appearing in the taskv3 chat after specific streaming sequences.
• Fixed aggressive autoscroll in the chat pane so manual scrollback is no longer interrupted by incoming tokens.
• Fixed live events auto-scroll direction and new-event highlighting on the Mission Control live feed.

Cloud update — 2026-04-15

Tags: 26.04.15-501 through 26.04.15-505.

New Features

Present mode

A new Mission Control “present” surface rolled out, making it easy to give a live walkthrough of what the agent is doing. Includes an early version of the timeline-as-presentation layout.

Fully functional team and account deletion

Teams and individual accounts can now be deleted from settings, with the full downstream cleanup (sessions, environments, integrations, subscriptions) wired up.

Nudge and queue on environment sessions

Dashboard task pages backed by remote environments now support nudges and queued follow-up messages the same way local sessions do.

Dark-mode error pages

Error and not-found pages were restyled to follow v3 design and respect dark mode.

Empty state for the side panel

The task side panel now has a proper empty state when no preview, browser, or terminal session is active.

PRs without a personal GitHub

You can now create and view PRs on a task even without a personal GitHub account connected — the team integration is used for the creation step.

Fixes

• Fixed the base-branch selection bug in the new-task flow where the wrong branch could be chosen if the user had no default set.
• Fixed a URL-clicking regression in the timeline.
• Fixed an images/default endpoint conflict affecting environment creation.
• Fixed the models endpoint location; it now sits under session/models with correct ingress routing.
• Better connection-state handling in the session context, so offline/connecting/live states surface accurately.
• Cleaned up the project settings panel layout.
• Unified sidebar and onboarding copy with consistent padding.

Cloud update — 2026-04-14

Tag: 26.04.14-500.

New Features

Renamed Projects to Repos, Deployments to Sites

User-facing terminology has been updated across the dashboard: Projects is now Repos and Deployments is now Sites, reflecting how customers actually refer to these objects.

Exported artifact transport for remote runners

Remote runner sessions can now transport exported artifacts (PDFs, plan markdown files, generated reports) back to the dashboard. The task page surfaces them inline.

Better seats/members handling

The team settings page now handles seat allocation and member management more reliably, including propagating role changes immediately.

Mobile view

An initial dedicated mobile view for the dashboard landed.

Fixes

• Fixed context-window token accounting — in-flight turn tokens are included in the progress HUD, eliminating the “looks fine but actually above the limit” discrepancy.
• Reverted an accidental firebase.ts change that broke auth in staging.
• Tightened interrupt handling so stopping a run feels snappier.

Cloud update — 2026-04-10

Tags: 26.04.10-498, 26.04.10-499.

New Features

Custom env support in shared components

The shared environment wizard components used by Desktop and the dashboard were unified so a custom env created in one surface is visible and editable from the others.

Extracted shared artifact and widget tool UI

The artifact/widget tool UI used in dashboard chat was extracted into shared components so the same rich artifact cards render in Desktop.

Fixes

• Fixed fresh Windows CLI installs failing to launch because of missing MinGW and libgcc DLLs — the CLI now statically links libgcc so the first launch on Windows works out of the box.
• Fixed Gemini reasoning payload handling in the chonkyllm proxy.

Cloud update — 2026-04-09

Tag: 26.04.09-497.

New Features

Desktop Onboarding v4

A refreshed Desktop onboarding experience rolled out end-to-end through the dashboard, covering auth, GitHub app install, team selection, and permissions.

Fixes

• Fixed macOS app icon generation and packaging for Desktop so the dock icon and Finder previews render correctly.

Cloud update — 2026-04-07

Tag: 26.04.07-496.

New Features

Big taskv3 / platform component pass

A large batch of taskv3 core-chat and home-dashboard tidy-up landed, removing dead code paths and lining up the dashboard’s chat pane with the Desktop surface. This also introduces an initial version of a shared “Platform Side Panels” abstraction.

TaskDiffResult.files always serialised

TaskDiffResult JSON now always includes an explicit files array (possibly empty) rather than omitting it, preventing a class of downstream null-handling errors.

Fixes

• MCP tool inventory is now resynced on every MCP status refresh, so MCP tool counts and availability stay accurate after reconnects.

Cloud update — 2026-04-01

Tags: 26.04.01-491 through 26.04.01-495.

New Features

Platform v3 UI

First wide rollout of the Platform v3 UI: agent event components, live event feed, side panels, and a cleaned-up sidebar. This is the basis of the taskv3 experience visible in today’s dashboard.

Import GitHub projects

A dedicated import flow for existing GitHub repositories was added, replacing the older catch-all “new project” path for users arriving with a GitHub repo in mind.

Desktop onboarding end-to-end

End-to-end desktop onboarding, including feature-flagged per-team rollout, is now production.

V3 task notifications

Notification plumbing was rewritten for v3 tasks so task status changes, new PRs, merges, and failures all surface in the notification center.

Configurable ripgrep backend

An optional ripgrep backend for grep tool calls landed behind a UI label, improving grep performance on large repos.

Deployments in the v3 sidebar

Deployments (now labelled Sites) are now reachable directly from the v3 sidebar.

Select base and new branch on cloud tasks

When you create a cloud task you can now pick both the base branch and the new branch name explicitly, rather than inheriting whatever the project default is.

Transcript overlay bottom-anchored

The transcript overlay now opens anchored to the bottom of the conversation and preserves scroll position when you close and reopen it.

Fixes

• Fixed a hydration bug in SessionActivationSignal that caused the session view to flicker on first paint.
• Fixed the websocket-effect exhaustive-deps lint error that was masking a stale-closure bug.
• Prevented the legacy shell from mounting on environment-backed tasks (the legacy shell no longer contends with the v3 environment shell).
• Fixed team-vs-team-slug confusion in the v3 task API endpoints.
• Surfaced agent errors into the UI instead of silently dropping them.

Cloud update — 2026-03 rollups

March 2026 deploys (26.03.03-484 through 26.03.29-<latest>).

New Features

Desktop onboarding foundation

Most of the building blocks for the Desktop onboarding flow landed on the dashboard side in March — auth session persistence, team detection, GitHub app install, and a dedicated onboarding sidebar.

Auto-tunnel URL for remote runtimes

Remote runtime sessions now auto-display a tunnel URL in the session header so you can open the pod’s exposed port directly from the dashboard.

Terminal command history, terminal button in chat header

Environment chat now includes a terminal button in the header, and the integrated terminal has command history across restarts.

Platform Side Panels skeleton

Initial structural work on the shared Platform Side Panels landed, later filled in by the April rollouts.

Fixes

• Fixed resume-history in the platform pane so resuming an old session rebuilds the timeline correctly.
• Fixed the task page mounting a legacy shell on environment-backed tasks.
• Reworked auth redirects to skip during local development, matching the CLI behaviour.

Cloud update — 2026-02 rollups

February 2026 deploys (26.02.16-478 through 26.02.23-483).

New Features

Login v2

A redesigned login2 flow rolled out with cleaner banners, clearer OAuth steps, and improved mid-flow error handling.

Project default branch from dashboard settings

You can now change a project’s default branch directly from the dashboard settings pane instead of relying on provider defaults.

Image builder wizard

A dedicated image builder wizard landed on the dashboard, letting you build and preview custom environment images without touching the CLI.

Feature flag infrastructure

Draft feature-flagging infrastructure (featureflagdraft) landed, powering gated rollout of the v3 UI and Platform work that followed.

Sidebar animation and consolidation

Dashboard sidebar was redesigned with cleaner animation, fewer dead entries, and unified badge styling.

Fixes

• Fixed deleted files showing wrong file paths in PR reviews.
• Fixed occasional 500s on the task endpoint caused by stale task context.
• Fixed Linux AMD64 and ARM64 build tagging that was missing from CLI rollouts.

Cloud update — 2026-01 rollups

January 2026 deploys (26.01.05-473 through 26.01.28-477).

New Features

Lumen Ultra

Lumen Ultra model support landed in the dashboard model picker, with Ultra mode using the orchestrator model for AutoPM.

Lumestral

Added Lumestral as a selectable model.

Images tab (feature-flagged)

A new Images tab on the Project surface (feature-flagged at first) exposes environment image management, image builds, and secrets per-environment.

Secrets for images

Secrets can now be attached to an environment image and are injected into builds and runtime.

Mistral Large for BNPP

Mistral Large was exposed as a selectable model for BNPP’s deployment.

Bitbucket hardening and visual polish

Multiple rounds of Bitbucket integration hardening and visual cleanups.

Fixes

• Warn on retry/edit when working changes exist, and reset the workspace before continuing to avoid mixing agent changes with yours.
• Fixed the New Task mode/preset bug where the mode picker did not honour the saved default.
• Fixed browser view not unmounting when navigating away.
• Removed the black border on the VNC viewer and cleaned up its styling.

Cloud update — 2025 highlights

The dashboard has been in continuous rollout since early 2025. Rather than enumerate every deploy tag, the highlights of the second half of 2025 are summarised below.

Q4 2025 (Oct–Dec)

• Swarm mode rolled into the dashboard alongside the CLI release, including Swarm QA verification agents and the Agents panel.
• Session Resume and persistent session state across browser refreshes.
• Cloud Environments UI: full environment management — creation, editing, secrets, pod size, base image — from the dashboard.
• Remote PTY sessions exposed through the dashboard’s integrated terminal.
• Auto-generated Dockerfiles for new environments.
• Desktop extension dashboard integration for signed-in Desktop sessions.
• Project indexing & memory tools surfaced on the task page.
• Tips and suggested tasks on the home surface.
• Azure DevOps integration POC.
• Headless Genie runs, dashboard PR review surface, and the Instant Sites integration all landed in this window.

Q3 2025 (Jul–Sep)

• Cosine CLI 1.0 launch — the dashboard received the task view, CLI auth, and linked-project infrastructure that supported the CLI 1.0 rollout.
• Remote tasks — remote task creation, viewing, and “Continue Locally” flows.
• File attachments on task creation.
• Unified ignorer and external-editor diff view across dashboard and CLI.
• Bespoke side-by-side diff viewer for reviewing agent changes.
• Large refactor of the taskv3 session pane, environment shell, and chat pane.

Q2 2025 (Apr–Jun)

• Cosine Genie CLI first introduced — dashboard-side task and inference wiring for the early CLI.
• Storybook-based design system for shared components.
• Ongoing cloud service migrations onto production charts (cosine-ha).
• Many foundational improvements to task execution, environment boot time, and integration coverage (GitHub, GitLab, Bitbucket, Jira, Linear).

Older releases

The cloud platform shipped daily prior to April 2025 but did not begin publishing dated YY.MM.DD-<run> release tags until the monorepo’s current deploy workflow landed. Earlier changes are tracked in the monorepo’s git history.
