IronPython 2.0.3 and 2.6 RC2

It has been a very busy week for the IronPython team. Just under a week ago, we shipped a CTP for .NET Framework 4.0. Since then, we’ve shipped two – yes, two! – more versions of IronPython. Three releases in one week! If we could keep up that pace, we’d be shipping like 27 more releases of IronPython by the end of the year!

FYI, we’re not going to keep up the pace of shipping three releases a week for the next two months. We may be a little crazy on the IronPython team, but we’re not THAT crazy!

Actually, all three of these releases represent fairly small changes in the IronPython source tree. The .NET 4.0 beta was a CTP, so it’s basically whatever we had in our main trunk when they forked .NET Framework for the beta.

IronPython 2.0.3 is a minor point release in the 2.0 branch (duh). In addition to backporting some fixes from 2.6, we had to fix an CLR breaking change in partial trust on Windows 7. If you’re using IronPython 2.0.x in partial trust on Windows 7 you MUST upgrade to 2.0.3 (or 2.6 when it’s released). Sorry about that – but it was out of our hands.

IronPython 2.6 RC2 is – as you would expect – a minor update over the first release candidate. There was a memory leak discovered in the hosting APIs which forced us to do a second release candidate. Since we had to fix that, we took in a few of other fixes including some standard library changes (we left out json by accident in RC1 and Michael Foord got logging updated to work better with IronPython so we took the latest version of it). As per the release notes, we expect this to be the final RC and will re-ship it as RTM in about a month. Please start using this latest release and let us know if you find anything.

Joining Windows

Big news in DevHawk land: I’ll be taking on a new role in the Windows division after I come back from TechEd Europe (plus a week vacation visiting my bro-in-law in Germany after TechEd).

You guys have heard of Windows, right? They just released a new version recently you might be aware of…Actually, I hear it was your idea!

Seriously, I am stoked to be joining the Windows team. I can’t say much about the new job beyond a) it’s in Windows Client (as opposed to Windows Server) and b) I’m working on a team that’s focused on the Windows developer experience. The Windows team is deep in what you might call “building on teh awesome that is Windows 7” but that they simply call “planning”, so sorry if specifics are kinda sparse. I’ll be back working for Mahesh Prakriya, who originally hired me into my current role on the IronPython team. Someday I might tell you the Mahesh PyCon Lego Story, but for now I’ll just say I was great working for Mahesh the first time and I think this time is going to be even better.

Working on Windows…focused on developer experience…for Mahesh – It’s like the perfect storm of work geekdom for me.

Of course, starting a new job means my time on the IronPython team is coming to an end. As excited as I am about this new opportunity in the Windows division, I’m a little sad to be leaving Developer Division and the IronPython team. I’ve joked with audiences that I care about Python because Microsoft pays me to care about Python, but that’s not completely true. Python is a fantastic language and IronPython’s combination of Python + .NET is hard to beat in my opinion. IronPython has made significant progress while I’ve been here the last eighteen months – two major releases (well, 2.6 is almost done), redisting the Python standard library, Visual Studio 2010 compat – but there’s still much for IronPython to accomplish. And of course, leaving behind such great teammates like Dino, Dave, Jim and Jimmy is ALWAYS hard.

The Windows team is somewhat tighter lipped than the totally transparent approach we use in IronPython. Not to worry, my evangelism skills were part of the reason I got the job so you’ll be hearing plenty from me soon enough. However, my posting here will be kinda sparse until I get my bearings over there. Until then, I’m sure that you will be absolutely fascinated by non-work-related-but-still-sometimes-geeky minutia I post on Twitter.
