0.0.18 - 2026-09-23

Release Notes

Added

• Added Meta Model API keys and Muse subscription device login.
• Updated the Pi model catalog with Claude Opus 5.5, GPT-6 Sol and Luna, Grok
  4.7, and Meta Muse models.

Changed

• Moved Jev reasoning selection to a checkpoint before each model generation,
  including the first response. Kept leased choices for later generations.
• Updated Pi compatibility to v0.87.1, including Grok 4.7 and Muse Spark 1.3
  provider defaults, Claude Code 2.1.280 request compatibility, and
  continuation-oriented split-turn compaction summaries.

Fixed

• Kept the ACP Cancelled stop reason when a task is cancelled during Jev
  preparation.
• Rejected stale Jev choices after a model or effort change, and showed the
  saved-effort fallback when Jev could not select an effort.
• Omitted empty text parts from image-only OpenAI-compatible messages, rejected
  invalid prompt frontmatter with a warning, and skipped late cache refreshes
  that would miss the existing prompt cache.

0.0.17 - 2026-09-22

Release Notes

Changed

• Expanded experimental TypeSafe Jev reasoning-effort selection to every
  reasoning model and provider, using each model's supported effort levels and
  existing provider-native mappings.

0.0.16 - 2026-09-22

Release Notes

Added

• Added experimental TypeSafe Jev reasoning-effort selection for GPT-6 Astra,
  with bounded runtime context, reusable generation leases, early reassessment
  after tool failures or new user input, and safe fixed-effort fallback.
• Added colored conversation-pane notices when Jev changes reasoning effort,
  using the same effort colors as the TUI input border.

Fixed

• Hid unsupported native terminal progress signals in Ghostty.

0.0.13 - 2026-09-19

Release Notes

Added

• Added historical cache-usage reports to kiss cache-usage and

  WebAssembly SDKs.

Fixed

• Made the doctor WebSocket probe use a valid 16-byte handshake key so strict
  servers do not reject a valid endpoint.
