OpenSquilla 0.5.3

OpenSquilla 0.5.3

Overview

OpenSquilla 0.5.3 is a maintenance release for the 0.5 stable line. It adds
durable Goal orchestration, makes long-running chats and queued follow-ups more
resilient, expands Skills and scheduling workflows, refines the Web and Desktop
interfaces, and strengthens recovery, upgrade, sandbox, provider, and usage
behavior.

Existing gateway configuration, chats, Agents, memory, and scheduled jobs stay
in place. The Gateway applies additive database migrations automatically; no
manual data transfer is required. Users upgrading from 0.5.2 should quit the
running Desktop app or gateway, install 0.5.3 directly over the current
installation, and restart OpenSquilla.

✨ What's Improved

Durable Goals and long-running tasks

• Goals can persist across turns and continue automatically with visible
  progress. Pause, resume, edit, clear, and Plan-mode deferral controls keep the
  user in charge of ongoing work.
• Goal state uses additive, automatically applied schema migrations and the
  same shared Agent, task, and turn runtime as ordinary chat. Existing sessions
  remain valid, and clients that do not use Goals continue through their
  existing paths.
• Long-running streams recover more cleanly from renderer reconnects and
  temporary activity gaps, with structured provider activity and bounded
  incremental rendering for large conversations.

Sessions, follow-ups, and history

• Queued follow-ups and attachments are durable across reconnects and preserve
  ordering when an active turn completes. Project handoffs and session forks
  keep their intended context without rewriting existing history.
• Session forks use an additive Gateway RPC and fail visibly and safely against
  older Gateways. No configuration migration is required.
• Compaction is request-safe and deployment-aware, prompt-cache continuity is
  more reliable, and artifact publication no longer depends on unrelated chat
  history work.

Chat and Desktop experience

• The responsive top bar, floating and collapsible composer, sidebar peer
  sections, created-chat cards, session counts, artifact presentation, and
  assistant-answer boundaries have been refined.
• Pending input, flattened tool markers, subagent titles, and streaming edit
  controls now reflect the actual task state more consistently.
• The landing-page “Build me a game” suggestion now sends only the visible,
  localized label. The previously bundled hidden detailed game prompt has been
  removed from every locale and is no longer sent by the client.
• Desktop diagnostics now capture renderer console and crash information, while
  startup ownership, profile targeting, and connection recovery are more
  reliable.

Skills, schedules, and providers

• Community Skills support immutable source resolution, transactional
  management, lifecycle diagnostics, and explicit compatibility boundaries for
  supported instruction-first packages.
• MetaSkills, inline /meta requests, Cron workspace management, disabled-job
  presentation, and default schedule handling are more consistent across the
  shared runtime and management surfaces.
• TokenRhythm model discovery combines the published catalog with declared
  credential entitlements, exposes additive catalog metadata, and clamps
  fallback output limits to the physical model's known capability.
• Model discovery adds optional metadata fields. Existing clients may ignore
  them; strict external decoders should allow the additions before upgrading.
• DeepSeek reasoning replay, provider idle handling, multiline TOML parsing,
  usage receipts on error paths, and model activity presentation are more
  reliable.

Recovery, upgrades, and platform reliability

• Recovery now reserves hard startup blocks for genuine profile locks and
  incompatible newer configuration. Corrupt configuration can be repaired from
  bounded backups with visible evidence, without discarding chats or other
  profile data.
• Update downloads prefer the verified OSS mirror and fail closed on checksum
  mismatches. Windows CI and packaging checks cover the supported release asset
  contract more consistently.
• Sandbox settings now cover Safe/Full defaults, versioned file, command, and
  network policies, live availability canaries, bounded recursive-delete
  backups, bundled runtime pins, LAN CIDR controls, and named tokens.
• TokenRhythm requests and LAN WebSocket access now follow tighter privacy and
  network safeguards. Existing privacy and telemetry opt-outs remain available.

• Windows x64: https://opensquilla-releases.oss-cn-beijing.aliyuncs.com/releases/latest/OpenSquilla-win-x64.exe

Each alias is replaced only after the published release passes checksum
verification. Versioned OSS and GitHub Release files remain available for
pinned downloads.

The Windows desktop installer is currently unsigned. See the
code signing policy
before installation.

No Windows Portable assets are published for 0.5.3. Existing 0.4.x Portable
downloads remain on their original release pages as legacy sources; do not
expect a 0.5.3 Portable zip or a Portable /releases/latest/download/ alias.

Container users can pull the multi-architecture gateway image:

docker pull ghcr.io/opensquilla/opensquilla:v0.5.3

The versioned image supports linux/amd64 and linux/arm64. The moving
latest tag follows the most recently verified release tag.

Upgrading from 0.5.2

Quit the running Desktop app and gateway before upgrading. Back up the active
profile first if you may need to recover or roll back.

Install 0.5.3 directly over 0.5.2. Existing configuration, chats, Agents,
memory, and scheduled tasks remain in the active profile. Additive database
migrations run automatically when the Gateway starts.

Important

On Windows, users coming from RC3 or an older pre-Preview-4 build must not
uninstall that build first: older uninstallers may delete
%APPDATA%\OpenSquilla. Back up that directory, then install 0.5.3 directly
over the existing installation. Preview 4, 0.5.0, 0.5.1, 0.5.2, and 0.5.3
installers preserve profile data during a normal uninstall.

On macOS, drag the new app into Applications, eject the DMG, and open the
Applications copy.

CLI users can reinstall the published wheel over the current tool environment:

uv tool install --python 3.12 --force --reinstall-package opensquilla \
  "opensquilla[recommended] @ https://github.com/opensquilla/opensquilla/releases/download/v0.5.3/opensquilla-0.5.3-py3-none-any.whl"

Non-user-initiated network observability can be disabled before startup with
OPENSQUILLA_PRIVACY_DISABLE_NETWORK_OBSERVABILITY=true or:

[privacy]
disable_network_observability = true

The compatibility variables OPENSQUILLA_TELEMETRY_DISABLED=true and
OPENSQUILLA_UPDATE_CHECK_DISABLED=true remain honored.
