Thanks for the correction!  My info is out of date, I'm sure you said at LISA08 you were intending to get cross-platform support in 1.4.  Maybe it just didn't make it in this time...

I've never seen the 0004 since we don't (yet) use HW RRAs at our site.

So, to clarify, 

RRDTool 1.0.x can READ/UPDATE 0001 and can CREATE 0001

RRDTool 1.2.x can READ/UPDATE 0001,0003 and can CREATE 0003

RRDTool 1.3.x can READ/UPDATE 0001,0003,0004 and can CREATE 0003,0004
(Version 0004 is only used if certain HW RRAs are active)

RRDTool 1.4.x will be the same as 1.3

RRDTool 1.5.x is intended to Read/update 0001,0003,0004,0005 and CREATE 0005 (platform independent)

Will you be dropping backwards support for old RRD formats in 1.5?  I think a lot of people still have some 0001-format RRDs lying around.  A conversion tool for 0001->0003 would probably be fairly easy to create...

From: Tobias Oetiker [tobi at oetiker.ch]

1.3 introduces format 0004 for new types of HW ... but this only
gets active when these types are configured

1.4 will not update the fileformat

1.5 will bring the cross platform format
