An anonymous reader writes: MINIX 3.2.0 was released today. Lots of code has been pulled in from NetBSD, replacing libc, much of the userspace and the bootloader. This should allow much more software to be ported easily (using the pkgsrc infrastructure which was previously adopted) while retaining the microkernel architecture. Also Clang is now used as a default compiler and ELF as the default binary format, which should allow MINIX to be ported to other architectures in the near future (in fact, they are currently looking to hire someone with embedded systems experience to port MINIX to ARM, see http://www.cs.vu.nl/~ast/job/).
