after upgrading Google Chrome to version 63.0.3239.84 I have started receiving errors and warnings
Just add autocomplete attribute to inputs and the warnings will disappear. For example:
<div class="form-group"> <input type="email" class="form-control" autocomplete="email" required> <input type="password" class="form-control" autocomplete="password" required></div>If you don't have or just don't want to set value for the attribute autocomplete use autocomplete="foo" so that warning message disappears.

They appear to have added this option recently, which hides recommendations:-source:recommendationin the filter box.
Found it by accident. The filter box also support auto-complete with Ctrl+Space (Windows).
