a Notifier or subclass after construction
* New 'examples' dir with some small example scripts

* Major reworking of underlying Loop implementation:
+ Unified low-level IO, timer and signal watches as callbacks
+ Split IO handle parts of Notifier into new IO::Async::Handle
class
+ Created Timer and Signal subclasses of Notifier
These changes will require a compatible upgrade to the underlying
Loop implementation.
* Hide SignalProxy and TimeQueue from CPAN's indexer, as they are
internal-only details that don't need exposing there.

Signal objects

->set_handle

(makes IPv6 work on platforms without IO::Socket::INET6)

callbacks
* Use signal names from Config.pm rather than relying on POSIX.pm.
Covers more signals that way

* Loop->requeue_timer()

subclass

CHANGES:
* Make sure that top-level objects are refcount-clean by using
Test::Refcount, and Scalar::Util::weaken()
BUGFIXES:
* Keep perl 5.6.1 happy by not passing LocalPort => 0 when
constructing IO::Socket::INETs

closed - allows for neater cross-connected Notifiers
* Made Notifier->want_{read,write}ready more efficient
* Notifier->close() on a child notifier works
* Loop->listen() should take the first successful address, rather
than trying them all
0.14 REMOVALS:

deprecated. Any attempt to use them will fail immediately.
ADDITIONS:
* 'keep' ChildManager operation

integration

0.10 INCOMPATIBLE CHANGES:
* Renamed events and methods in IO::Async::Notifier to better fit the
naming scheme of normal Perl handles. Backward-compatibility hooks

code using the old names should be updated

variances at test time
* Avoid bugs in post_select()/post_poll() caused by some notifier
callbacks removing other notifiers from the set
0.07 BUGFIXES:
* Avoid race condition in t/30childmanager.t - wait for child process
to actually exit

for SIGCHLD+pipe close, rather than SIGCHLD+pipe data
0.06 CHANGES:
* Allow 'env' setup key to ChildManager->spawn() to change the
child's %ENV
* Updated the way some of the ->spawn() tests are conducted. There
seems to be massive failures reported on cpantesters against 0.05.
These changes won't fix the bugs, but should assist in reporting
and tracking them down.
BUGFIXES:
* Don't rely on existence of /bin/true - test for /usr/bin/true as
well, fall back on "$^X -e 1"

* Buffer now has on_read_error / on_write_error callbacks for
handling IO errors on underlying sysread()/syswrite() calls

installed but carry on anyway.
* IO_Poll->loop_once() now returns the result from the poll() call
* Added concept of nested child notifiers within Notifier object
BUGFIXES:
* Fix to test scripts that call IO_Poll's loop_once() with a timeout
of zero. This can cause a kernel race condition, so supply some
small non-zero value instead.
0.02 INCOMPATIBLE CHANGES:
* Event methods/callback functions now called "on_*" to distinguish
them
* Callback functions now pass $self as first argument to simplify
called code
CHANGES:
* Improved POD in Notifier.pm and Buffer.pm
BUGFIXES:
* GMainLoop.pm - return 1 from callbacks so that glib doesn't remove
our IO sources
* GMainLoop.pm - make sure re-asserting want_writeready actually adds
the IO source again
0.01 First version, released on an unsuspecting world.
