WordBrain 0.2.0

What's Changed

WordBrain v0.2.0 replaces the bundled three-tier dictionary stack with a single
private Dictionary API. The renderer no longer ships an offline dictionary — it talks
to a server you configure under Settings → Dictionary API. API keys are encrypted
on disk (macOS Keychain on Apple targets, Stronghold on Linux/Windows) and never
reach the renderer.

Breaking changes

• Offline ECDICT lookup is gone. The 93 MB ECDICT bundle no longer ships, and the
  dictionary_entries / word_translations_cache tables are dropped. Existing v0.1.x
  installs upgrading to v0.2.0 will need a Dictionary API server configured for word
  lookups to work.
• Custom MDict import + cloud upload removed. The MDict importer, the R2/S3 upload
  flow, and the Dictionary / Upload Server / API Keys settings panels are no longer
  part of the app. Any custom dictionaries imported in previous versions are no longer
  accessible.
• BYOK provider list narrowed to openai | anthropic | ollama. Youdao and DeepL
  slots have been removed.

New

• Dictionary API settings panel with enable/disable, server URL field, encrypted
  API-key slot, and a one-click "Test connection" button.
• macOS Keychain backend for the BYOK key vault — fast, system-managed encryption
  on Apple targets while Stronghold continues to back Linux/Windows.
• is_in_srs IPC + cargo test, used by the lookup modal to decide whether a word
  is already scheduled.
• Vitest coverage for WordLookupModal.

Improvements

• Cargo dependency surface trimmed (sha2, hex, rand, base64, mdict-rs, plus
  the wordbrain-resource-manager workspace crate are removed).
• Schema simplified: the SQLite DB no longer carries dictionary or custom-dictionary
  tables.

Install

• Homebrew (macOS): brew install dickwu/tap/wordbrain (or brew upgrade wordbrain
  if already installed)
• Direct download: pick the artifact for your platform from the assets below.
