GLPK 4.60:
Some improvements were made in the primal and dual simplex
solvers to make the solution process more numerically stable.
An experimental long-step ratio test feature was added to the
dual simplex. On API level this feature is available thru the
GLP_RT_FLIP option. For glpsol it is available thru the options
--flip (for MIP) or --flip and --dual (for LP). This feature is
not documented yet.
Additional check was added to reject wrong solutions sometimes
reported by the PROXY heuristic.
A bug (memory leak) was fixed in the FPUMP heuristic routine.
The header sql.h was renamed to avoid conflicts with standard
ODBC headers.
