[dchassin]

Coding

• Group data and variable linkage (done in Release 4.3.16 #326)
• Object data and variable linkage (done in Release 4.3.16 #326)
• Global data and variable linkage (done in Release 4.3.16 #326)
• Fix dual variable linkage
• Data type mapping on dynamic set_value
• Properties list on dynamic models
• Powerflow module network linkage
• Unit conversion on static models
• Fast data copy to cvx (no size limit) (done in Release 4.3.16 #326)
• Parametric problem statements (done in Release 4.3.16 #326)
• Add cvxpygen of parameterization
• Add “status” property inaccurate check (done in Release 4.3.16 #326)
• Add support for “valid-to” variable (fixed in Release 4.3.16 #326)

Validation

• Finalize the comprehensive syntax tests (done in Release 4.3.16 #326)
• Modify cases to allow check of OPF result (done in Release 4.3.16 #326)
• Create a FD/OPF test case (done in Release 4.3.16 #326)
• Linux validation procedure fails even though models work ok individually (Release 4.3.16 #326)

The design of the dual variable implementation is flawed and needs to be redone.
