576 * Add missing headers into release tarball:
577 urcu-call-rcu-impl.h and urcu-defer-impl.h
579 2011-06-10 Userspace RCU 0.6.0
580 * Added call_rcu() support, graciously contributed by Paul E. McKenney.
581 * Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS)
582 into a single .so: liburcu-cds.so to have a single header/shared
583 object holding all concurrency-aware data containers. It provides
584 support for RCU lists, queues and stacks at the moment.
585 * liburcu 0.6.0 now allows linking a single application with multiple
586 flavors of RCU. This required a library API change which is
587 incompatible with older 0.5.x liburcu. The .so version number
588 is therefore bumped from 0 to 1 (e.g. liburcu.so.1).
589 * Added "atfork" handling API, documented in README. Only useful for
590 processes using fork() without following exec().
591 * Renaming the following files, keeping the old files (producing a
593 urcu/uatomic_arch.h -> urcu/uatomic.h
594 urcu/urcu-futex.h -> urcu/futex.h
595 urcu/urcu_ref.h -> urcu/ref.h

606 to handle fork gracefully. These disable signals and hold
607 the registry mutex across forks. (this flavor of the liburcu
608 library ("bp" for "bulletproof") is mainly used by UST, the
611 2011-03-03 Userspace RCU 0.5.3
612 * Add support for older ARM single-CPU architecturess (pre-ARMv7)
613 (thanks to Jason Wessel from WindRiver).

615 * Remove leftover list_t type from urcu/list.h (namespace cleanup).
616 * urcu_defer: handle malloc error value.
617 * Update README file to describe urcu interaction with fork() when not
619 by an exec() system call.

627 2010-11-18 Userspace RCU 0.5.0
628 * Version 0.5.0 changes the API presented by memory model,
629 architecture abstraction and data structure primitives in
630 headers. The prefixes are, respectively:
631 - cmm_ : Concurrent Memory Model
632 - caa_ : Concurrent Architecture Abstraction
633 - cds_ : Concurrent Data Structures
635 2010-03-04 Userspace RCU 0.4.2
636 * Add generic uatomic ops support.

641 * s390: compilation fix.
643 2010-01-30 Userspace RCU 0.4.0
644 * API change: SIGURCU -> SIGRCU

646 * API change: urcu_init -> rcu_init.
647 * urcu/config.h options renamed to CONFIG_RCU_HAVE_FENCE,
648 CONFIG_RCU_HAVE_FUTEX, CONFIG_RCU_SMP, CONFIG_RCU_COMPAT_ARCH.
649 ((moving from URCU -> RCU).
650 * library names changes: liburcu becomes the "default" version, using
651 sys_membarrier() when available, and using liburcu-mb as a
653 * The signal-based liburcu is renamed from liburcu to
654 liburcu-signal. People previously using the signal-based
655 "liburcu" will automatically be moved to the "default" liburcu

676 2009-10-02 Userspace RCU 0.2.1
677 * small header dependency fix for rculist.h.
678 * new "liburcu-bp.so" : "Bulletproof RCU", made especially for
679 the UST userspace tracer. It's a library that sacrifices a bit
680 of read-side performance for automatically monitoring thread
681 creation/removal. See README for details.
683 2009-10-01 Userspace RCU 0.2
684 * Clarify usage of rcu_cmpxchg_pointer, rcu_xchg_pointer,
