A beta version of MiKTeX 2.9 is now available. The main new feature is the integration of LuaTeX (see the relesae notes).

You can download MiKTeX 2.9 Beta here.

If you find a bug, then please write a bug report or post a message to the MiKTeX mailing list.

Bug fixes will be made available via the update wizard, hence I don't think that there will be second Beta. MiKTeX 2.9 will be released in October.

MiKTeX 2.9 (to be released this month) supports the following operating systems:

• Windows 7
• Windows Vista with Service Pack 2 (all editions except Starter Edition)
• Windows XP with Service Pack 3 (all editions except Starter Edition)
• Windows Server 2008 R2
• Windows Server 2008 with Service Pack 2
• Windows Server 2003 R2
• Windows Server 2003 with Service Pack 2

MiKTeX 2.9 will not run on Windows 2000. This is a breaking change.

A GNU/Linux version of MiKTeX 2.9 is not planned at this time.
