Presence is back, sharper chat, and Course Studio polish

This release brings online presence back across chat, sharpens how mentions and message actions work, polishes the Course Studio learning experience, and rounds things out with billing, notification, security, and stability improvements.

See who's online again

Online status is back across the app. The home "who's online" chip, your direct message list, and the channel member list all show who's currently active again. Your own name now appears the way your teammates see it, so you're labeled consistently everywhere.

Sharper mentions and message actions

Thread previews in the sidebar now show @names instead of raw mention markup, and hovering any message action button shows a tooltip so it's clear what each one does. Mentioning a specialist works regardless of capitalization, reactions apply instantly, and copying a message gives clear confirmation.

Course Studio improvements

• A K-Flow demo app link on the course home page lets you visualize the product world behind the exercises.
• The exercise Guide now opens the brief in the Exercise panel, and reference files open directly in the code panel.
• Stakeholder specialists show their names with roles, e.g. "Derek Choi (Engineering Lead)".
• Evaluations run on your messages with a retry after failures, attempt cards on Home link straight to the full attempt view, workshop content is refreshed with corrected lesson order, and the page width is tidier.

Chloe posts as Chloe

Channel posts authored by the Chloe assistant now show up as Chloe, so it's clear when a message came from the assistant.

Clearer path when usage runs low

Billing now gives clearer guidance and a smoother path when you're running out of subscription usage.

A Workspaces tab in notifications

Notifications gain a dedicated Workspaces tab, and the inbox is more accurate and free of duplicates at startup.

Security updates

Picked up the latest security fixes across underlying dependencies.

Polish & fixes

• Home side panels now respect feature flags, and priority widgets wait until the workspace is ready before loading so you no longer see a spurious error on cold start.
• The editor/side-panel resize handle is wider and easier to grab.
• The command palette can jump straight to Tasks or Knowledge.
• Consistent topbar action-icon color, a compact workspace watermark preview, an aligned workspace-details skeleton, and email content that no longer overflows.
• Member inputs no longer trigger browser autocomplete, sign-in defers invite links until you're signed in, and clearing app data now also clears the saved sign-in keychain.
• More consistent right-click context-menu behavior across the app.
