Ubuntu Lucid (10.04) is essentially a snapshot of Debian as it is now, 
modulo a few new versions/packages that we don't have. I haven't 
checked, but I suspect we will be almost-2009.2.0.2-compliant. It's 
probably fair to say that platform compliance wasn't top of my agenda 
with this release; the 6.12/provides transition managed to take over 
somewhat.

Let's have a look at how well we are doing with the platform.

I've had a look at the release schedule for the platform, and it seems 
that it's unfortunately somewhat out of sync with the Ubuntu release 
schedule. See

  https://wiki.ubuntu.com/LucidReleaseSchedule

for the Lucid schedule, for example. The date to look at is Feature 
	Freeze, which is the last date for new upstream releases to enter 
	for the next release. The platform releases being after this date 
		(and aligned on a 6 month schedule) means that we are likely to 
		lag behind by one platform release.

I still do think that we (Ubuntu) can do better for users though. I'll 
try to ensure in future that I stick to versions of packages specified 
in the platform, after choosing the platform version to support for a 
release. As far as I know we are doing this in the DHG as well too — 
albeit on a rolling basis— so this shouldn't be a problem.

We can probably get some tools to help here.

Joachim, do you think it would be possible to update your script that 
feeds Hackage to also supply Ubuntu data? I don't know if it would be 
best to track the development or stable release, though.

In addition to supplying Hackage, we can use this data to automatically 
generate a platform/archive status page by parsing the platform's cabal 
file. I'll try and do this.

Cheers,
Iain
