ChangeLog *********** release of 0.12.1 20070117 Bug-fix of RST. -src/rise_set.c check_coords function, rewrite H1 checks, fix some nasty bugs which were there. -lntest/test.c Additional tests for RST functions (hyp_future_rst_test). Fix RST tests - error will be displayed if libnova calculates wrong circumpolar value. Petr Kubanek 20070117 Future functions, which calculated next rises. -src/rise_set.c -src/libnova/rise_set.h Add _next_rst_future functions. -src/elliptic_motion.c -src/libnova/elliptic_motion.h -src/parabolic_motion.c -src/libnova/parabolic_motion.h -src/hyperbolic_motion.c -src/libnova/hyperbolic_motion.h Add _next functions (and their variants). -lntest/test.c Add test for new functions (ell_rst_test, body_future_rst_test functions). Petr Kubanek 20070116 libnova is now ported to Win32 with the following changes. -src/julian_day.c Added preprocessing directive for POSIX header (sys/time.h) exclusion for Win32 compilation. Changed ln_get_date_from_sys to be compatible with Win32. -src/misc.c Added preprocessing directive for POSIX header (unistd.h) exclusion for Win32 compilation. Changed libnova.h include to libnova/libnova.h. -src/utility.c Added preprocessing directive for POSIX header (unistd.h) exclusion for Win32 compilation. Added functions gettimeofday, gmtime_r, and strtok_r to substitute for their POSIX coupterparts. Added functions cbrt, nan, and round to subsistute, in C89, for their C99 counterparts. -src/libnova/ln_types.h Added definitions of struct timeval and struct timezone to subtitute in Win32 for their POSIX counterparts. -src/libnova/utility.h Added include of time.h.
