ENet 1.3.18 (April 14, 2024): * Packet sending performance improvements * MTU negotiation fixes * Checksum alignment fix * No more dynamic initialization of checksum table * ENET_SOCKOPT_TTL * Other miscellaneous small improvements ENet 1.3.17 (November 15, 2020): * fixes for sender getting too far ahead of receiver that can cause instability with reliable packets ENet 1.3.16 (September 8, 2020): * fix bug in unreliable fragment queuing * use single output queue for reliable and unreliable packets for saner ordering * revert experimental throttle changes that were less stable than prior algorithm ENet 1.3.15 (April 20, 2020): * quicker RTT initialization * use fractional precision for RTT calculations * fixes for packet throttle with low RTT variance * miscellaneous socket bug fixes ENet 1.3.14 (January 27, 2019): * bug fix for enet_peer_disconnect_later() * use getaddrinfo and getnameinfo where available * miscellaneous cleanups ENet 1.3.13 (April 30, 2015): * miscellaneous bug fixes * added premake and cmake support * miscellaneous documentation cleanups ENet 1.3.12 (April 24, 2014): * added maximumPacketSize and maximumWaitingData fields to ENetHost to limit the amount of data waiting to be delivered on a peer (beware that the default maximumPacketSize is 32MB and should be set higher if desired as should maximumWaitingData) ENet 1.3.11 (December 26, 2013): * allow an ENetHost to connect to itself * fixed possible bug with disconnect notifications during connect attempts * fixed some preprocessor definition bugs ENet 1.3.10 (October 23, 2013); * doubled maximum reliable window size * fixed RCVTIMEO/SNDTIMEO socket options and also added NODELAY ENet 1.3.9 (August 19, 2013): * added duplicatePeers option to ENetHost which can limit the number of peers from duplicate IPs * added enet_socket_get_option() and ENET_SOCKOPT_ERROR * added enet_host_random_seed() platform stub ENet 1.3.8 (June 2, 2013): * added enet_linked_version() for checking the linked version * added enet_socket_get_address() for querying the local address of a socket * silenced some debugging prints unless ENET_DEBUG is defined during compilation * handle EINTR in enet_socket_wait() so that enet_host_service() doesn't propagate errors from signals * optimized enet_host_bandwidth_throttle() to be less expensive for large numbers of peers ENet 1.3.7 (March 6, 2013): * added ENET_PACKET_FLAG_SENT to indicate that a packet is being freed because it has been sent * added userData field to ENetPacket * changed how random seed is generated on Windows to avoid import warnings * fixed case where disconnects could be generated with no preceding connect event ENet 1.3.6 (December 11, 2012): * added support for intercept callback in ENetHost that can be used to process raw packets before ENet * added enet_socket_shutdown() for issuing shutdown on a socket * fixed enet_socket_connect() to not error on non-blocking connects * fixed bug in MTU negotiation during connections ENet 1.3.5 (July 31, 2012): * fixed bug in unreliable packet fragment queuing ENet 1.3.4 (May 29, 2012): * added enet_peer_ping_interval() for configuring per-peer ping intervals * added enet_peer_timeout() for configuring per-peer timeouts * added protocol packet size limits ENet 1.3.3 (June 28, 2011): * fixed bug with simultaneous disconnects not dispatching events ENet 1.3.2 (May 31, 2011): * added support for unreliable packet fragmenting via the packet flag ENET_PACKET_FLAG_UNRELIABLE_FRAGMENT * fixed regression in unreliable packet queuing * added check against received port to limit some forms of IP-spoofing ENet 1.3.1 (February 10, 2011): * fixed bug in tracking of reliable data in transit * reliable data window size now scales with the throttle * fixed bug in fragment length calculation when checksums are used ENet 1.3.0 (June 5, 2010): * enet_host_create() now requires the channel limit to be specified as a parameter * enet_host_connect() now accepts a data parameter which is supplied to the receiving receiving host in the event data field for a connect event * added an adaptive order-2 PPM range coder as a built-in compressor option which can be set with enet_host_compress_with_range_coder() * added support for packet compression configurable with a callback * improved session number handling to not rely on the packet checksum field, saving 4 bytes per packet unless the checksum option is used * removed the dependence on the rand callback for session number handling Caveats: This version is not protocol compatible with the 1.2 series or earlier. The enet_host_connect and enet_host_create API functions require supplying additional parameters. ENet 1.2.5 (June 28, 2011): * fixed bug with simultaneous disconnects not dispatching events ENet 1.2.4 (May 31, 2011): * fixed regression in unreliable packet queuing * added check against received port to limit some forms of IP-spoofing ENet 1.2.3 (February 10, 2011): * fixed bug in tracking reliable data in transit ENet 1.2.2 (June 5, 2010): * checksum functionality is now enabled by setting a checksum callback inside ENetHost instead of being a configure script option * added totalSentData, totalSentPackets, totalReceivedData, and totalReceivedPackets counters inside ENetHost for getting usage statistics * added enet_host_channel_limit() for limiting the maximum number of channels allowed by connected peers * now uses dispatch queues for event dispatch rather than potentially unscalable array walking * added no_memory callback that is called when a malloc attempt fails, such that if no_memory returns rather than aborts (the default behavior), then the error is propagated to the return value of the API calls * now uses packed attribute for protocol structures on platforms with strange alignment rules * improved autoconf build system contributed by Nathan Brink allowing for easier building as a shared library Caveats: If you were using the compile-time option that enabled checksums, make sure to set the checksum callback inside ENetHost to enet_crc32 to regain the old behavior. The ENetCallbacks structure has added new fields, so make sure to clear the structure to zero before use if using enet_initialize_with_callbacks(). ENet 1.2.1 (November 12, 2009): * fixed bug that could cause disconnect events to be dropped * added thin wrapper around select() for portable usage * added ENET_SOCKOPT_REUSEADDR socket option * factored enet_socket_bind()/enet_socket_listen() out of enet_socket_create() * added contributed Code::Blocks build file ENet 1.2 (February 12, 2008): * fixed bug in VERIFY_CONNECT acknowledgement that could cause connect attempts to occasionally timeout * fixed acknowledgements to check both the outgoing and sent queues when removing acknowledged packets * fixed accidental bit rot in the MSVC project file * revised sequence number overflow handling to address some possible disconnect bugs * added enet_host_check_events() for getting only local queued events * factored out socket option setting into enet_socket_set_option() so that socket options are now set separately from enet_socket_create() Caveats: While this release is superficially protocol compatible with 1.1, differences in the sequence number overflow handling can potentially cause random disconnects. ENet 1.1 (June 6, 2007): * optional CRC32 just in case someone needs a stronger checksum than UDP provides (--enable-crc32 configure option) * the size of packet headers are half the size they used to be (so less overhead when sending small packets) * enet_peer_disconnect_later() that waits till all queued outgoing packets get sent before issuing an actual disconnect * freeCallback field in individual packets for notification of when a packet is about to be freed * ENET_PACKET_FLAG_NO_ALLOCATE for supplying pre-allocated data to a packet (can be used in concert with freeCallback to support some custom allocation schemes that the normal memory allocation callbacks would normally not allow) * enet_address_get_host_ip() for printing address numbers * promoted the enet_socket_*() functions to be part of the API now * a few stability/crash fixes
