Backwards compatibility

Old YALMIP code (version 2.4) is 99% compatible with the version 3, but there are a few changes (backwards compatible if not otherwise stated).

Solving problems

• The solvers SP and SOCP are no longer supported.
• SDPT3 version 3.0 and earlier is no longer supported.
• CSDP version 4.5 and earlier is no longer supported.
• solvesdp has a new input syntax.
• Initial guesses are now given using the field usex0 in sdpsettings (not backwards compatible).
• When savesolverinput and savesolveroutput are activated, the data is saved in the fields solution.solveroutput and solution.solveroutput (small letters, not backwards compatible).

Obsolete functionalities

• addlmi is obsolete (use overloaded + or &).
• dellmi and updatelmi are obsolete.
• pretty is obsolete.

Changed command names

• The command set replaces lmi. 
• The command yalmiptest replaces dbtest.

Options

• The field silent in sdpsettings does not exist anymore. Use verbose instead.
• The field sedumi.maxradius in sdpsettings does not exist anymore. Use the general field radius instead.
• The field sedumi.removeequalities in sdpsettings does not exist anymore. Use the general field removeequalities instead.
