Release 1.0.0-alpha.18

Breaking changes

• XML-based device support has been removed. The "non950type" module — covering both XMPP/XML and MQTT/XML protocol variants — has been deleted entirely. Devices that communicated via these older protocols are no longer supported. Only JSON-based MQTT devices ("950-type" and later) remain supported.
• Node.js ≥ 22.15 is now required. Older versions are no longer supported.
• The native node-canvas dependency has been removed entirely (see Map rendering below). Any project that relied on it being a transitive dependency must install it directly.

New features

• The map rendering stack has been completely rewritten in pure JavaScript
  • A custom framebuffer, PNG encoder, and rasterizer for map overlays replace the previous node-canvas dependency.
  • Live map rendering with piece tracking and validation is now included, along with zstd decompression support for map data.
• Promise-based command execution
  • runAsync() provides a promise-based API for sending commands and awaiting their response.
  • A new PendingCommandRegistry tracks in-flight commands and routes responses back to their callers.
• Shared MQTT connections
  • connectShared() allows multiple VacBot instances to share a single MQTT client connection, reducing resource usage when managing a fleet of devices.
• Revised device support
  • Optional auto-empty station capability
  • smartType / productIotMap for internal IoT protocol resolution
  • deviceType property on model definitions
  • Heuristic model resolver for discovery and similarity analysis

Developer ergonomics

• sendCommand() convenience wrapper on VacBot
• ApiDevice typedef for type-safe device objects
• client property exposed on VacBot
• Case-insensitive command registry lookup

Bug fixes and improvements

• Model dictionaries are now frozen at load time and deep-clone calls on hot paths have been removed, reducing GC pressure during high-frequency message handling.
• MQTT client ID now includes a truncated device ID suffix to ensure uniqueness when connecting multiple devices.
• Incoming MQTT messages with malformed JSON are now caught and logged rather than crashing the handler.
• set-prefixed commands are excluded from command name normalization to prevent misrouting.

Infrastructure

• Docker support added with a Dockerfile and updated local deployment docs.
• ESLint migrated to flat config format; linting added to CI.
• Removed all native build dependencies from the Dockerfile (no more node-gyp, python, make, etc.).
• Comprehensive unit test coverage added for map decoding, MQTT message parsing, command dispatch, and model capability regression testing.
