This is a pretty big breaking change: the html output by qweb is now
different.
The main goal is to optimize the compiled templates:
- condense all consecutive whitespaces into a single spaces
- if possible, drop completely some text nodes, based on the following
heuristic: if a text node is only composed of whitespaces, and
contains at least one linebreak, then it can be dropped.
This leads in my benchmark test to an improvement of about 10%, in
rendering speed and in memory consuption.
Note: whitespace here means anything that matches the \s regexp: newlines,
tabs, ...
