**For using PDAF_assimilate in flexible mode**

**[wiki:PortingToPDAF3 Porting to PDAF-3]**
- PDAF_interfaces_module now named PDAF; mandatory to use
- subtype=5 for specifying the offline mode was removed; use PDAF_set_offline_mode
- additional parameter in PDAF_assimilate_lnetf and PDAF_put_state_lnetf
- porting from PDAFomi to PDAF3 for global filters: Just change the name of the routine
- porting from PDAFlocalomi to PDAF3 for local filters: Just change the name of the routine
- porting from PDAFomi to PDAF3 for local filters: The PDAF3 interface uses PDAFlocal so that the routines g2l_state_pdaf and l2g_state_pdaf are not present. Follow the implementation guide for init_dim_l to initialize the information for PDAFlocal
- porting from classical PDAF interface with fully specification of all call-back routines: See implementation guide (PDAF3 uses both PDAF-OMI and PDAF-local to provide compact interfaces)
- porting from PDAFomi or PDAFlocalomi for 3D-Var: Change the name of the routine
- check subtype: 0 and 1 are unchanged; for others: 2=>10, 3=>11, 4=>2, 6=>3, 7=>4
- the option to run the offline mode as 'subtype=5' was removed. It is now require to call "PDAF_set_offline_mode"
