Changelog

2026-05-02

Activity feed

• New Activity page in the sidebar — a real-time log of everything happening across your workspace.
• Three tabs: For You (events relevant to you — your submissions, approvals, rejections, XP, badges), My Brands (all events on brands you belong to), and Workspace (every event across the studio, admins only).
• Filter chips narrow the feed to specific event types: approvals, drafts, feats, or level-ups.
• Time filter lets you scope to today, the past 7 days, 30 days, or all time.
• Infinite scroll with cursor-based pagination — the feed stays fast as history grows.

Campaign tagging across the full workflow

• Tag assets with brand campaigns at two entry points: the Generate page (at creation time) and the Library detail panel (after the fact). The Review modal shows campaign assignments read-only.
• Campaign chips appear on asset cards in the Library so you can scan which initiative an asset belongs to without opening it.
• Workspace teammates can now edit tags and campaign assignments on any shared asset — previously limited to the asset’s creator.

Public campaign galleries

• Share a campaign’s approved assets with anyone — no login required.
• Each campaign gets a shareable public URL at /brands/[slug]/campaigns/[campaign-slug]/public.
• Only approved assets are visible. Draft, in-review, rejected, and archived assets stay private.
• Brand managers control which campaigns have a public gallery.

Threads everywhere

• Threads (introduced in Library on 2026-05-01) are now available in the Gallery and Review modal as well — the Thread tab appears on any asset wherever you open it.

2026-05-01

Now called OpenCauldron

• The studio is officially OpenCauldron — the styleguide, sidebar branding, and downloaded filenames all carry the new name.
• Saved files now download as opencauldron-{id}.webp / opencauldron-{id}-original.{ext} (was cauldron-…).
• The seed brand previously named “Cauldron” is renamed to “OpenCauldron” in place — same brand, new label, no asset moves.
• Self-host setup wizard defaults the R2 bucket to opencauldron.

Filmstrip in the review modal

• Inside the review modal, a horizontal filmstrip rail at the bottom now shows what’s coming next and what just passed — no more guessing where you are in the queue.
• Click any thumbnail to jump to that asset; the active tile auto-scrolls into the center as you walk the queue with j/k.
• Approved/rejected items stay in the strip, dimmed with a check or X marker, and j/k automatically skip over them so you only land on what still needs a decision.
• Hovering a thumbnail shows the asset’s prompt as a tooltip — useful when 52–64px thumbs aren’t enough on their own.
• Honors prefers-reduced-motion: the strip jumps instantly instead of smooth-scrolling when the OS preference is set.

Threads on every asset

• Every Library asset now has a Thread tab — pin a conversation right next to the work itself, not in a separate Slack channel.
• Messages stream in real time, so a teammate’s note shows up the moment they hit send.
• React with any emoji, @-mention a workspace member, or reply to a specific message to keep tangents readable.
• Paste or drag images, GIFs, and video clips straight into a message — they upload inline and render in the thread.
• Attach an existing Library asset to a message with one click — the recipient sees a tactile asset card that opens the original.
• Mention notifications drop into your bell with a deep-link that opens the asset and jumps to the message.

Downloads work again

• Fixed Download in the Gallery and Library failing with a silent error on hosts where the storage bucket isn’t CORS-configured.
• Files now stream through the app, so the browser always treats them as a download (with the right filename) instead of opening them in a new tab.

2026-04-30

Review queue opens into a gallery

• Picking a brand on /review now shows a scannable gallery of pending assets — no more forced single-item modal flow.
• Click any tile (or press Enter on it) to open the existing review modal at that asset.
• Closing the modal returns you to the gallery; only the last asset reviewed pops back to the brand list.
• Loading, empty, and error states get tasteful Card treatments — including a Try again button if the queue fetch fails.

Faster image previews + pick your download size

• Library and Gallery full-size previews now load a compressed WebP version — typically 90%+ smaller than the original, way faster on slow connections.
• Download button is now a split button: one tap grabs the smaller WebP for sharing, or open the menu to pick the original at full quality.
• File sizes are shown right in the menu so you know what you’re getting.
• Mobile gets a single full-width download button that always opens the menu — easier to tap.
• Originals are never modified — the WebP is purely additive and silently falls back to the original if anything goes wrong.

Self-hosted Docker distribution

• Self-host OpenCauldron with Docker — docker compose up -d and you’re running.
• Pre-built multi-arch images for Apple Silicon, Intel/AMD, and Raspberry Pi 4+.
• Database migrations and admin bootstrap run automatically on first boot.
• One-line upgrade path — docker compose pull && docker compose up -d.

Library, upgraded for teams

• Workspace admins now see every brand’s assets in the Library — not just their own.
• Brand filter shows all the brands you have access to, with personal libraries labelled by member name and avatar so multiple Personals are easy to tell apart.
• Each thumbnail now shows a status chip (Draft, In review, Approved, Rejected, Archived) so you can scan workflow state without opening the asset.
• A creator avatar in the bottom-right of every card shows who uploaded or generated it — hover for their name and the action.

Send feedback from Slack

• Type /feedback in Slack to fire off a quick note, bug report, or Loom link straight to the team.
• A short form keeps your feedback in context — no copy-paste, no lost threads.

Prompt enhancer, redesigned

• Enhance now lives inside the prompt box — one tap rewrites your prompt in place, no extra panel to expand.
• Hit Cmd/Ctrl+E to rewrite without leaving the keyboard.
• Don’t love the rewrite? An Undo pill appears for 8 seconds to put your original prompt back.
• Click the ▾ next to Enhance for templates (style, lighting, composition, mood, quality) — selections clear after each run so they don’t pile up.
• On phones the options open as a bottom sheet for easier tapping.

Prompt enhancement is live again

• Click ✨ Enhance on the prompt box to rewrite your idea into a more detailed prompt.
• Powered by Mistral — set MISTRAL_API_KEY in your env to enable it.
• Tuned per model — gpt-image, Imagen, Flux, and video providers get model-specific phrasing tips.

Cleaner error messages

• When a provider rejects a generation, the toast now shows the actual reason instead of the raw API response.
• Your prompt and signed asset URLs stay out of error messages.
• Applied across every image and video model.

OpenAI image editing

• OpenAI gpt-image models can now edit existing images — drop a reference into Generate and they’ll follow your edit prompt directly.
• Up to four reference images at once for compositing — describe how each should be used in your prompt.
• gpt-image-1 and gpt-image-1.5 use high input fidelity automatically, tuned to preserve faces and fine detail across edits.
• Defaults updated to follow OpenAI’s prompting guide — medium quality and opaque backgrounds for more consistent results.

OpenAI gpt-image-2

• OpenAI’s newest image model is now available — sharper instruction-following and higher-fidelity image inputs.
• Picked automatically when you select OpenAI in Generate; older versions (1.5, 1.0, Mini) live under the variant selector.
• Heads up: gpt-image-2 doesn’t support transparent backgrounds yet — use 1.5 if you need an alpha channel.

In-app notifications

• New bell in the sidebar shows submits, approvals, and rejections as they happen.
• Unread count pill on the bell, with a “Mark all read” action in the popover.
• Click a notification to jump straight to the brand’s review queue.
• XP, level-ups, and badge unlocks now toast after every successful generation.

Delete brands you no longer need

• Brand managers can now delete a brand from the brands list (⋯ menu on each row) or from the brand’s settings page (new Danger Zone).
• When deleting, choose what happens to the brand’s assets and brews: move them to another brand, or delete them along with the brand.
• Type the brand’s name to confirm — same pattern as GitHub repo deletes.
• Personal brands are hidden from this flow — they’re system-managed and stay tied to your account.
• The brands list also stops showing other teammates’ Personal brands; you only see your own.

Home page with quick actions

• Renamed Overview to Home — same page, friendlier name.
• New action strip up top: Text → Image, Image → Image, Text → Video, Animate.
• Each tile drops you into Generate with the right mode preselected — Image → Image even picks Flux Kontext for you and opens the reference picker.

Move assets between brands

• Asset detail panel now has a “Move to brand…” action so a miscategorized asset can be reassigned to the correct brand.
• Available to the asset’s creator, brand managers on the source brand, and workspace admins — approved assets must still be forked, not moved.
• Moving an asset resets its status to draft so the new brand’s reviewers can vet it.

Workspaces are now Studios

• Renamed Workspace to Studio across the app — same thing, friendlier name.
• New Studio settings page at /settings/studio for renaming, changing the slug, or pinning a logo URL.
• The sidebar studio row now clicks straight through to Studio settings.

• API for tagging assets with campaigns is live; gallery filter chip ships next.

Three-level brew visibility

• Brews are now Private (just you), Brand (everyone on the brand), or Public (Explore tab).
• Promoting a brew to Public still requires a brand manager — creators can flip Private↔Brand on their own.
• Every visibility change is logged so you can see who shared what and when.

Brand-first sidebar + workspace overview

• Sidebar reorganized — Overview, Personal, Review, then a brand list with one row per client/division.
• New /overview page shows your drafts, your pending review queue, recently approved work, and personal stats.

• Per-brand pages live at /brands/[slug]/{gallery,brews,kit,members,review}.

Brand kit panel on the generate page

• See exactly what your brand kit will inject before you submit — prefix, suffix, banned terms, default LoRAs, anchor refs.
• Override toggle dims the panel and skips kit injection for one-off generations.
• Personal brands skip the panel; their kit is empty by design.

Drag-and-drop uploads

• New Upload button in the gallery — drop existing photos or short videos straight in.
• Up to 50MB per file; supports PNG, JPEG, WebP, GIF, MP4, MOV, WebM.
• Uploads land as drafts on the brand you pick, ready for the review pipeline.
• Per-file progress with a cancel button — no surprise stuck uploads.

Gallery now scoped to your brands

• Status badges on every tile — draft, in review, approved, rejected, archived.
• Filter the gallery by status or brand; filters survive in the URL so you can deep-link a view.
• You only see assets you created or that live on a brand you’re a member of.
• Empty states distinguish “no matches” from “no access to this brand”.

Review queue (early access)

• New Review tab in the sidebar with a pending-count badge for brand managers.
• Submit a draft for review from the asset detail dialog — your brand manager picks it up from the queue.
• Keyboard-driven approve/reject modal: j/k to walk the queue, a to approve, r to reject, n for a note.
• Approved assets are now immutable — use Edit / Fork to start a new draft from an approved version.
• Personal-brand assets stay out of the review pipeline as expected.
