Changelog for event
Release What has changed?
3.1.3 EventDnsBase::__construct() now throws a TypeError if the type of the $initialize argument is anything other than int or bool.
3.1.2 Fixed an issue in EventDnsBase::__construct() where it failed to accept the init flag set to true when using libevent version < 2.1.0.
3.1.1 Fixed build in RHEL 7 and 8 (thanks to Remi Collet).
3.1.0 Stable version based on 3.1.0RC1. Refer to release notes of 3.1.0RC1 for details.
3.1.0RC1 - The loop will now be stopped if an event callback throws an exception.
This prevents user from losing control on the event loop.
- EventDnsBase::__construct() now accepts bool|int as its second parameter:
* false and true have the same meaning as before;
* EventDnsBase::DISABLE_WHEN_INACTIVE - Do not prevent the libevent event loop from exiting when we have no active DNS requests.
* EventDnsBase::INITIALIZE_NAMESERVERS - Process resolv.conf.
* EventDnsBase::NAMESERVERS_NO_DEFAULT - Do not add default nameserver if there are no nameservers in resolv.conf.
- Internally, a safer strlcpy() will be used instead of strcpy().
- Fixed a segmentation fault that might occur in the EventHttpRequest callback.
- Fixed a bug where the EventBuffer::copyout method didn't populate the output variable properly in PHP >= 8.2 (thanks to Joseph Tseng).
3.0.8 Set --with-openssl-dir configure option to "yes" by default.
3.0.7 Added support for in-tree build (PR https://bitbucket.org/osmanov/pecl-event/pull-requests/18/support-in-tree-build by dixyes)
Fixed tests/27-event-util-create-socket_php8.phpt on macOS
3.0.7RC1 Fixed #69: The event loop remained running when the user called exit() or an exception was thrown from the event callback. Now in these cases the loop will be stopped automatically.
3.0.6 Fixed tests for the builds in debug mode where libevent complained about STDIN and STDOUT being not set to non-blocking mode
Fixed build with OpenSSL 3.0 (Thanks to Remi Collet).
3.0.5 Fixed a test not working with PHP 8.1.0alpha1
3.0.4 Internal changes: Created a non-fastcall wrapper for zend_objects_new().

3.0.2r1 Stable version release.
3.0.2 - Fixed #65: some methods had wrong argument/return type hints
3.0.1 - Fixed #64: build failed to find arginfo.h when invoked via pecl install event-beta
3.0.0 - Added PHP8 support.
- Introduced strict type hinting.
- Removed deprecated EventBufferEvent::sslFilter method.

2.4.3 Fixed config.w32 to take in account newer OpenSSL, which fixes build with PHP 7.2 (by Anatol Belski).

Fix: compilation warnings regarding OpenSSL features deprecated in version 1.0.0 and newer.
Deprecated: EventSslContext protocol version options are deprecated for OpenSSL >= 1.1.0.
Use the new setMinProtoVersion and setMaxProtoVersion methods instead.

SSL Fixes:
- chained self-signed certificate failed to pass with EventSslContext::OPT_ALLOW_SELF_SIGNED = TRUE
- the server didn't set the list of CAs to be sent to the client when requesting a client certificate for underlying SSL structure
- EventSslContext::OPT_ALLOW_SELF_SIGNED = TRUE accepted any self-signed certificate without regard to OPT_CA_FILE/OPT_CA_PATH

- SSL leaks
- Possibility of implicit destruction of user vars
- Unclean SSL bufferevent shutdown

2.0.0RC1 PHP7 support added.

- issue #23: memory leak in EventHttpConnection close callback + memory leaks in HTTP callbacks.
- Libevent 'unrecoverable' fatal errors(fixed by stopping the loop in EventBase free-storage handler).

API changes:
- EventUtil::createSocket method added(PHP7)
- The first(EventBase) argument of EventBufferEvent::sslFilter method is deprecated, since the internal EventBase object must match EventBase object within the underlying EventBufferEvent
- Added EventBufferEvent::createSslFilter method as a replacement for the sslFilter method.
1.11.3 Issue #20: SSL_GET_PREV_SESSION:session id context uninitialized
1.11.2 Issue #6: memory leaks in EventHttp callbacks.
EventBufferEvent object returned by EventHttpRequest::getBufferEvent() should be freed explicitly,
if the method is called from a userspace callback.
1.11.1 Fixed build with old openssl (RHEL-5) (thanks to Remi Collet)
1.11.0 Fix: exceptions thrown from EventHttp and EventBufferEvent userspace callbacks were not passed through back to user.
Now the event loop will break and re-throw the exception.

Fix: EventListener cached file descriptor for all connections
0.9.1 Added event_timeout() function for easily scheduling a callback after a certain
period of time. The timeout may be persistent to make the callback a recurrent
