PDF.js 5.0 is a major release that contains a number of API changes, features and bugfixes.

The following significant new features are highlighted:

  • Improved JPEG 2000 decoding support
    • The OpenJPEG decoder was moved into a separate .wasm file, which requires setting a new wasmUrl API option in order to use it; see PR #19329.
    • A (much slower) JavaScript OpenJPEG fallback decoder was added (also uses the wasmUrl API option) for environments without WebAssembly support; see PR #19525.
  • Support for ICC profiles
    • This requires WebAssembly support, and that the wasmUrl API option is set; see PR #19564.
    • Use an ICC profile to improve CMYK to RGB color conversion, which requires setting a new iccUrl API option in order to use it; see PR #19620.
    • Currently Lab profiles are not supported, which is tracked in bug 1717767.
  • Improved rendering of large pages in the viewer
    • Render the currently visible portion of pages at full resolution, once we've reached the size limits and are falling back to CSS-zooming; see PR #19128.
    • Limit the maximum canvas dimensions, to avoid rendering breaking and canvases being empty; see PR #19604.
  • Enable creation of hyperlinks, in the viewer, from text that look like URLs
    • This is disabled by default because of some remaining issues, but can be enabled in the viewer with the enableAutoLinking option/preference; see PR #19110.

The following significant changes are highlighted (which may require changes in third-party PDF.js implementations):

  • Addition of a couple of new CSS variables, that e.g. the text and annotation layers now depend upon; see PR #19469.
  • Removal of a couple of old exceptions; see PR #19264.

The complete list of changes in this release is shown below. If you're upgrading to PDF.js 5.0 we recommend checking the changes prefixed with [api-minor] and [api-major] since those might require updates to your code.
