Changes from libparticle 0.4.2 to 1.0.0:

1) changed building system from Visual Studio to scons.

2) added void p_util_perror( char* str ) function 

3) renamed p_socket_send_file to p_socket_send_buffer 

4) added p_socket_send_file (which takes a filename as parameter)

5) init the socket sequence number with random

6) added p_socket_set_option for setting several socket-options with one function; deleted p_socket_set_broadcast, p_socket_set_blocking, p_socket_set_recv_option, p_socket_set_frag_option and p_socket_set_autoack.
Please make the following changes in your programs:
p_socket_set_broadcast(socket) -> p_socket_set_option(socket, SOCKET_BROADCAST, 1)
p_socket_set_blocking(socket, 0/1) -> p_socket_set_option(socket, SOCKET_BLOCKING, 0/1)
p_socket_set_recv_option(socket, 0/1) -> p_socket_set_option(socket, SOCKET_RECV_ALL, 0/1)
p_socket_set_frag_option(socket, 0/1) -> p_socket_set_option(socket, SOCKET_FRAG, 0/1)
p_socket_set_autoack(socket, 0/1) -> p_socket_set_option(socket, SOCKET_AUTOACK, 0/1)

You can also set several options at the same time if you want to set them to the same value. For example:
p_socket_set_recv_option(socket, 1);
p_socket_set_frag_option(socket, 1);

can be done by 
p_socket_set_option(socket, SOCKET_RECV_ALL|SOCKET_FRAG, 1);

7) deleting ack-packtes that have already been received; use p_oscket_set_lastacks to set the number of packets that will be stored.

8) p_socket_set_option (SOCKET_BROADCAST)  is now setting the correct local broadcast-address

9) new function p_util_get_local_interfaces


Changes from libparticle 0.4.1 to 0.4.2:

1) IMPORTANT: p_socket_send_file and p_socket_send_file_str have been renamed
   to p_socket_send_buffer and p_socket_send_buffer_str. p_socket_send_file
   from libparticle 0.4.2 is a new function, which really send's a file and
   not only a buffer!

2) Again a change of the output-dir, it's now \bin and not src\bin.

3) Changed the internal handling of some of the socket-options. It's recommended
   to use p_socket_set_option.

4) Corrected some of the returns in case of error.

5) Fixed an error in the dsp-file of the fragrepeater from the unit-test.

6) p_socket_send* will now return -1 and EINVAL if you try to send a packet which 
   doesn't include any ACL-tuple.

7) Improved the documentation for the filters (see doc of p_filter_add)

8) added p_acl_add_tuple (adding an existing ACL-tuple to an CL-paket) and
   p_acl_remove_tuple (removing an ACL-tuple from a packet)

9) implemented get_functions for the socket-data. Deleted d_get_socket, 
   please use the new functions p_socket_get*

10) update for the debian-files.

11) updated the make-files for unix.

12) Included the *.opt-files for Visual Studio

13) moved filter-enums from _filter_enum.h to filter.h; deleted _filter_enum.h

Changes from libparticle 0.4.0 to 0.4.1:

1) Output of all projects is now \bin\[Debug or Release]\. You can now make
   changes to libparticle and can run the unit-test or other apps without
   moving lipparticle.dll to another directory.

2) The "Additional include directorys" have been set to the correct path to
   the lib-sources.

3) p_socket_recv_filtered returns now NULL and EAGAIN if the recvd packet didn't
   match the filter. 

4) p_socket_close() interrupts a blocking p_socket_recv_* function

5) The unit tests now opens the repeater and the frag_repeater automaticly under
   linux and windows

6) analyzer can recieve filtered packets. run analyzer without an argument to get
   more infos / help.

7) sendtoparticle can now send normal packets, addressed packets, acknowleged packets
   and frags. run sendtoparticle without an argument to get more infos / help.
