[bitbake-devel] [PATCH][1.30] lib/bs4: Fix imports from html5lib >= 0.9999999/1.0b8

Mon Sep 4 11:44:12 UTC 2017

From: Daniel Lublin <daniel at lublin.se>

As of html5lib 0.9999999/1.0b8 (released on July 14, 2016), some modules
have moved from _base to base. Handle this, while staying compatible
with earlier versions.
