Rationale

There is a bunch of legacy code which is not even tested:
https://app.codecov.io/gh/python-pillow/Pillow/pull/8211/blob/src/PIL/WebPImagePlugin.py#L50
All Pillow capabilities require libwebp 0.5.0, which was released in Dec 2015.

Removed APIs

  • features.check("transp_webp"): Deprecated, will be removed in 12
  • features.check("webp_mux"): Deprecated, will be removed in 12
  • features.check("webp_anim"): Deprecated, will be removed in 12
  • _webp.WebPDecoderVersion(): not documented and has alternative: _webp.webpdecoder_version
  • _webp.WebPDecoderBuggyAlpha(): not documented
  • _webp.HAVE_WEBPANIM: not documented
  • _webp.WebPDecode(): obsolete webp decoder
  • webpmux compiling options

IIRC, some of that was for webp as shipped in debian derived distributions, now long deprecated.

features.check("transp_webp")
features.check("webp_mux")
features.check("webp_anim")

Removing these without warning sounds a little concerning to me - using them doesn't mean someone is using software from 9 years ago, merely that they are supporting the idea of other people doing so.

@radarhere pretty reasonable. I've moved them back.
