BeOS & Derivatives Haiku Alpha 3 has been in development for more than 14 months. In that time more than 800 bugs have been identified and fixed, major sections have been updated, applications have been added and updated, and great progress has been made in supporting additional hardware. Here is a summary of updates, more details can be found here. Also inside, interviews with some core Haiku developers.

RE[4]: Looking Forward to Haiku

minix isn't a hybrid. it is a true micro-kernel. Technically, none of the above are true micro-kernel OS's. (I think the OS-periment by Hadrien Grasland is attempting to be a true micro-kernel design. At least that is the way I read it).

Yup ;) I'd never have thought that my pet project would be used one day in an argument about micro vs monolithic kernels...

In the micro family, one can add QNX, Mach, L4, and I think that Symbian too has a microkernel structure but check my words on that. Tanenbaum also mentions some microkernels used in critical environments on his website.

I don't think Be or Haiku is micro, either, but a hybrid (which is just that, a hybrid. It has micro-kernel features and monolithic features.)

I always have a hard time defining hybrids myself ;) Most known hybrids sound to me like extremely modular monolithic designs : a huge lot of functionality is still in kernel mode, sharing a common address space, but in separate and easily replaceable code modules.
