Millistream Data Feed API (MDF) version 1.0.18 is released

Millistream is pleased to announce the release of version 1.0.18 of our open
source Data Feed API.

* updated mdf_fields.h to the latest version (44 new fields and 2 new messages,
also note that the MDF_F_FREETEXTCOMMENTx fields have been renamed to MDF_F_Sx)
* fixed the code so that it builds correctly on a big endian system
* fixed various compiler warnings
* fixed wrong encoding of the values “10741.80” and “10741.90”, decoding
was not afflicted so this only applies if you use the MDF to send data
into the system.
* new function mdf_message_add_time2() added that allows adding of time
without having to go by strings.
* new function mdf_message_add_date2() added that allows adding of date
without having to go by strings.

As usual this version of MDF is binary compatible with previous versions, so
there is no need to recompile client applications, so users (including users of
the Java JNI wrapper) can simply upgrade by replacing the libmdf file itself.
