One month ago I wrote about the Library Operating System for Linux (LibOS) and initial reaction to that independent project led to an interesting range of responses. A month later, LibOS is still being worked on for Linux.

The Library Operating System (LibOS) for Linux is trying to build the Linux kernel's network stack as a shared library so that user-space programs can access it directly, simulations be easily done by researchers, etc. See the earlier article for more details.

The news today is that LibOS remains in development and is now up to LibOS v3. The new version adds a new "SLIB" library allocator, the log messages have been improved, etc. The V2 of LibOS that was recently published is compatible with the Linux 4.0.0 kernel and makes other improvements.
