Hello, 
there are some patches that we created to support features in our
calendar system. 
Patches eds-* are meant to evolution data server and evo-* are for
evolution package. 
It was testedagainst 2.26 release, so i hope it will work with current
developement version of evolution.

add CAL_STATIC_CAPABILITY_NO_SEND_IMIP calendar capability

From: Ondrej Jirman <[email protected]>

calendar/ChangeLog:

2008-04-06  Ondrej Jirman  <[email protected]>

	** Fix for bug #not yet submitted

	* libecal/e-cal-util.h:
	Add new capability CAL_STATIC_CAPABILITY_NO_SEND_IMIP to disable sending
	of iMIPs and conversion of attachment URLs to 'CID:...' by evolution.

	This is used by calendar backends that want to send iTIPs and upload
	attachments to a calendar server.

don't cache read only status in ECal

From: Ondrej Jirman <[email protected]>

calendar/ChangeLog:

2008-04-06  Ondrej Jirman  <[email protected]>

	** Fix for bug #525231

	* libecal/e-cal.c: (e_cal_is_read_only):
	Don't cache read_only flag on the client side. Always ask backend plugin
	for the current status of the read_only flag. Some calendar plugins
	allow for changes between read-only/read-write status of the calendar
	on the fly (for example because of change in the calendar ACL).
