2007-12-29 Frank Benkstein <frank-vlock@benkstein.net>

	are now silently stripped from erroneous names instead of reported as errors.
	* Fixed a file descriptor leak in script handling.
	* Fixed a bug where vlock would run in an infinite loop if not started from
	a terminal.  Now it simply exits.

2007-11-28 Frank Benkstein <frank-vlock@benkstein.net>

	vlock 2.2 rc3

	* A critical security problem (local root exploit) was fixed:
		Previous versions of vlock (since 2.2 alpha1) contained a serious flaw
		that allowed any user to execute arbitrary code as root .  This was
		possible because plugin names could contain "../" thus escaping the
		pre-defined plugin directory.  All users of vlock 2.2 development versions
		are advised to update.
	* Improved script handling.
	* Added two more scripts.
