708 * Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS)
709 into a single .so: liburcu-cds.so to have a single header/shared
710 object holding all concurrency-aware data containers. It provides
711 support for RCU lists, queues and stacks at the moment.
712 * liburcu 0.6.0 now allows linking a single application with multiple
713 flavors of RCU. This required a library API change which is
714 incompatible with older 0.5.x liburcu. The .so version number
715 is therefore bumped from 0 to 1 (e.g. liburcu.so.1).
716 * Added "atfork" handling API, documented in README. Only useful for
717 processes using fork() without following exec().
718 * Renaming the following files, keeping the old files (producing a
720 urcu/uatomic_arch.h -> urcu/uatomic.h
721 urcu/urcu-futex.h -> urcu/futex.h

777 * library names changes: liburcu becomes the "default" version, using
778 sys_membarrier() when available, and using liburcu-mb as a

805 * new "liburcu-bp.so" : "Bulletproof RCU", made especially for
806 the UST userspace tracer. It's a library that sacrifices a bit
