fronalabs/frona v2026.5.3

on GitHub

This release is a big push on channels and harness scheduling. Frona gains four new messaging adapters Slack, WhatsApp (Cloud + Personal), Discord, and Signal, plus per-channel retry policies, exponential-backoff reconnects, and unified outbound delivery with dispatch-mode awareness. The cron/scheduling system is now timezone-aware end-to-end (server + user TZ, temporal_context in prompts) and surfaces recurring tasks in the UI with next-run times and a runs table. Under the hood, the browser stack was migrated from browser-use to a new in-tree frona-browser crate on chromiumoxide, rig-core was upgraded to 0.37 (with OpenAI gpt-5/o-series fixes), and Cedar policy gained a User principal alongside new admin endpoints and a Users settings UI.

Harness

• Add CronRun task model with per-fire chats, centralized SSE, and a scheduler service with broadcast e2e tests.
• Surface cron tasks in the Tasks panel with a Recurring badge and next-run time; show cron runs table in the task UI.
• Split the cron tool surface and tighten task-execution rules in agent prompts.
• Make the scheduling pipeline timezone-aware: add ServerConfig.timezone with a TZ detection chain, User.resolved_timezone helper with TZ validation on profile update, chrono-tz + iana-time-zone dependencies, and a Timezone section in the setup wizard and settings page.
• Expose server_timezone in /api/system/info; render task_time in the user's TZ and inject a temporal_context block into the system prompt.
• Route cron messages to the source chat and recover crashed fires; broadcast task_update on cron creation.

Channels (Experimental)

• Add Slack adapter (Socket Mode), with bot-auth and connect logs split for clearer diagnostics.
• Add WhatsApp Cloud API adapter and WhatsApp Personal (wa-rs) adapter, including a markdown-to-WhatsApp formatter and rendered manifest markdown in the setup UI.
• Add Discord channel adapter.
• Add Signal channel adapter (presage-based) with markdown → Signal BodyRange conversion and structured-output extraction for Signal-mode inference.
• Add ChannelConfig with a default retry policy; expose per-channel retry overrides on the channel config page and persist them on create/update.
• Retry failed channel connections with exponential backoff; add ChannelManager::report_failure for gateway adapters and a cancel token on ChannelCtx.
• Extend channel manifest and ChannelCtx with setup hooks; allow the Start button on channels in Setup status and stop start_channel from writing Setup (which previously broke the watcher loop).
• Unify message broadcast and presigning inside chat_service; stamp delivery lazily and reconcile orphans on channel start.
• Make outbound delivery per-message dispatch-mode aware; persist Message.dispatch_mode for inbound Signal-fallback authorization; skip empty user-side messages when building inference history.

Browser

• Migrate browser stack from browser-use to a new in-tree frona-browser crate based on chromiumoxide.
• Pin browserless/chromium to v2.42.0.

Policy / Admin

• Add User principal to the Cedar policy engine.
• Add admin endpoints and a Users settings UI.
• Add auth.allow_registration config flag.

Inference

• Upgrade rig-core to 0.37.
• Fix OpenAI provider for gpt-5 / o-series models.

Credentials

• Remove the Keeper vault provider and Keeper UI/docs (drop keeper-secrets-manager-core).

Identity

• Route the update_identity tool through AgentService; normalize attribute keys to lowercase and reject inline data: URLs.
• Replace AgentResponse.avatar with avatar_url
• Derive bon::Builder on UpdateAgentRequest; add bon dependency.

Frontend

• Bump frontend dependencies to latest within semver.
• Add description prop to ComboboxInput.
• Fix react-hooks/exhaustive-deps warnings.

Build / Infra

• Install protobuf-compiler in Docker builders (required by presage/Signal).
• Ignore stray root node_modules and .vite caches.
• Build Docker images before pushing release tags, with automatic rollback on failure.
• Add OCI version, revision, and created labels to published images.
• Bump pinned apt and pip packages to latest.
