naptha/tesseract.js v6.0.0 on GitHub

What's Changed

Fixed memory leaks (#977)
- This version fixed a long-standing issue where memory would rise over time, eventually leading to a crash.
Reduced runtime and memory usage for most users by updating default formats (#916).
Fixed compatibility with Electron main process (#925)
Fixed bug where user-provided parameters were overwritten by defaults (#975).

All outputs formats other than text are now disabled by default.
- To re-enable the hocr output (for example), set the following: worker.recognize(image, {}, { hocr: true })
  - See here for a list of possible output formats.
The JavaScript object output format (blocks) was tweaked.
- Only the array of blocks (blocks) is returned.
  - Previous versions would automatically generate lists of every unit of text (words, symbols, etc.).
    - If needed, these should now be generated by the user.
- Only text-based blocks are reported.
  - Previous versions reported non-text blocks when detected by Tesseract (e.g. line segments).
- The shape of some objects were changed.
  - See the type declarations for reference on properties.
  - The main properties--text and bbox--are unchanged.
Various functions and options marked as depreciated previously have been removed.
1. This includes worker.initialize and worker.loadLanguage, along with several depreciated options from v2.

See #993 for additional discussion about this release.
