- Added new
[`Cshort_To_Gr_Complex`](https://gnss-sdr.org/docs/sp-blocks/data-type-adapter/#implementation-cshort_to_gr_complex)
Data Type Adapter implementation.
- The
[Osmosdr_Signal_Source](https://gnss-sdr.org/docs/sp-blocks/signal-source/#implementation-osmosdr_signal_source)
has gained two new optional configuration parameters: `iq_balance_mode` and
`dc_offset_mode`, both of which are set to Automatic by default.
### Improvements in Portability:
