(*) Fixed: udpxrec would not write beyond 2Gb; -M option would not accept >2Gb of size
Build 7 (20-September-2008)
(*) Fixed: multicast-resubscribe default period of zero seconds would cause udpxy to resubscribe
on every iteration; logic changed to make udpxy re-subscribe only on setting's value >0

(*) SIGPIPE is ignored now (was handled as a signal to quit)
(*) Full version info is displayed on exit

(*) default buffer size changed to 4K, was 64K
(*) minimal send-socket buffer length set to 32K (was previously set to data buffer size)
(*) UDPXY_SENDBUF_LEN environment variable can be set to control send-socket buffer size
Build 10 (24-February-2009)
(*) read-socket buffer left untouched if bigger than suggested buffer value based on -R
and -B parameters and the minimum buffer size - currently 32K - for send socket
(*) UDPXY_SENDBUF_LEN replaced by UDPXREC_SOCKBUF_LEN: that will be the minimum size
for both read- and send-socket buffers (ignored still if set to less than 32K)
(*) send-socket buffer size will be enlarged to the size of read-socket bufffer size
(if currently smaller)
Build 11 (25-February-2009)
(*) UDPXY_DSOCKBUF_NOSYNC set to 1 will leave send-socket buffer size unaltered
(*) UDPXY_SSOCKBUF_NOSYNC set to 1 will leave read (mcast)-socket buffer size unaltered
(*) default buffer size (-B) changed to 2K, was 4K
(*) default value for -R (messages to buffer) set to 1
(*) minimum (advisory) socket buffer size set to 64K, was 32K
(*) Fixed: assert when processing RTP-TS with -R 1
(*) Fixed: if2addr() not working under 64-bit linux; -a and -m options would not accept ifc names
(*) Fixed: quit flag value cast incorrectly under 64-bit linux
(*) CFLAGS variable may used for additional compiler options (CFLAGS='-m32' will force 32-bit build, for instance)
(*) NOP statements in udpxy.c, udpxrec.c updated to compile w/o warnings under gcc 3.2.3
(*) util/mkipk.sh script added to create IPKG packages
Build 12 (9-April-2009)

Build 16 (21-Mar-2010)
(*) FIXED: hanging when specifying network interface by name
Build 17 (27-Jun-2010)
(*) FIXED: server terminates on ECONNABORTED from accept()
(*) Dynamic memory allocation for HTTP status pages implemented - will not truncate pages
Build 18 (9-Jan-2011)
(*) IP/port separator in HTTP request to udpxy can be any of those: ":%~+-^"
Build 19 (9-Jan-2011)
(*) MAX limit of clients (-c option) upped to 5,000 (five thousand)
Build 20 (18-Jun-2011)
(*) FIXED: player sends last request's traffic to any client with invalid request;
(*) FIXED: unsupported HTTP requests (those that the parser does not handle) are denied [ID: 3294265]
(*) Added UDPXY_SREAD_TMOUT, UDPXY_SWRITE_TMOUT evn parameters to set read/write timeouts on HTTP server's socket;
(*) Added UDPXY_HTTP200_FTR_LN, UDPXY_HTTP200_FTR_FILE env parameters to allow appending 1 line or contents
of a text file to HTTP 200 (successful request processing) response;
(*) Added Content-type entry to HTTP response;
(*) Added conditional compilation of udpxrec - use NO_UDPXREC=yes make [mode] to *NOT* build udpxrec into the udpxy
binary
Build 21 (25-Nov-2011)
(*) FIXED: defunct processes appear at a high volume of requests;
(*) FIXED: ECONNRESET, ECONNABORTED and EPROTO in accept cause server to exit prematurely;

(*) FIXED: conflict with dirent.h (DT_UNKNOWN) resolved;
Patch 2 (20-Dec-2011)
(*) FIXED: misc build errors and inconsistencies
Patch 4 (9-Feb-2012)
(*) FIXED: SIGSEGV caused by dpkt.c:upxfmt_NAME[] having less members than indexes used (RAW was missing);
(*) rdebug (release with debug symbols), ldebug (lean with debug symbols) targets added;
Build 22 was skipped to avoid confusion with patches and betas pulled off github;
Build 23 (3-Jul-2012)
(*) HTTP response lines are now separated by CRLF (not just LF), as per RFC2616;
(*) SO_REUSEPORT used (where available) to allow more that one client
to subscribe to the same channel on BSD-derived systems;
(*) optimization patches by Alexey Suhinin integrated (tcp_nodelay, pause_timeout, mstream_type);
(*) sloop.c uses syscall.h & -DUSE_SELECT to alternate between select(2)- and pselect(2)-based implementations of server loop
(*) FIXED: idle timeout displayed incorrectly in select(2)-based version;
(*) HTTP response includes 'Server:' clause;
Patch 1 (31-Aug-2012)
(*) Added the capability to capture the HTTP variables submitted via URI beyond command/options
Example: http://hostname:port/udp/mcaddr:mcport?aa=1&bb=2&cc=3 - '?aa=1&bb=2&cc=3' part is now
preserved (for each client) and displayed in status page as part of Destination column;
(*) Added README.russian;
Patch 2 (14-Oct-2012)
(*) Static linking enabled through LDFLAGS=-static (as a prefix to make);
(*) EPIPE and other 'not really errors' should not go to syslog (time-outs still WILL);

Patch 5 (13-Dec-2012)
(*) Makefile corrections (purged deprecated options & variables);
Patch 6 (23-Dec-2012)
(*) report_status() adjusts report-buffer size for client tails;
(*) attempt to fix strict-aliasing compiler warnings in sock_info();
(*) optimizing: removed difftime() as redundant on a POSIX system (may affect non-POSIX ports).
Patch 7 (24-Dec-2012)
(*) more work on report_status() to prevent memory exhaustion when using 'tails' in requests;
