0.5.0 was released on the 25th of March, 2009, in the morning.
The very same day, several changes were made to sudoers.aug involving
the negate node:
commit 468976635238ce814d954b7d44df3b7b41121f87
Author: David Lutterkort <lut...@redhat.com>
Date: Wed Mar 25 12:21:44 2009 -0700
Sudoers: produce at most one negate node
Even if there are multiple '!' signs, only produce one negate node.
commit c35ad5aef2069b39472e209c8700e13706bef8fe
Author: Raphael Pinson <raph...@gmail.com>
Date: Wed Mar 25 09:36:01 2009 -0700
Sudoers: fix ticket #48
* make a difference between boolean and non boolean values for integers and
strings
* allow multiple negate flags (odd/even numbers change the behaviour)
* add optional double quotes to integer and string field
Bug reported by Frank Sweetser
In fact, this one _introduced_ the negate flag, which should then have
been absent from 0.5.0 as far as I can tell.
