- Replaced `git://` by `https://` as the used protocol when downloading Gflags,
so it can work through firewalls requiring authentication.
- Fixed static linking of the matio library when downloaded and built by CMake.
- Fix building with `-DENABLE_CUDA=ON` for blocks implemented with CUDA.
### Improvements in Usability:
@ -42,7 +43,14 @@ SPDX-FileCopyrightText: 2011-2020 Carles Fernandez-Prades <carles.fernandez@cttc
v0.0.13. This change recovers the old behavior.
- Fixed the termination of the receiver with `q` + `[Enter]` keys when using the
`Osmosdr_Signal_Source` implementation of the `SignalSource` block.
- The `Labsat_Signal_Source` implementation of the `SignalSource` block now can
be throttled with the new parameters `SignalSource.enable_throttle_control`
and `SignalSource.throttle_frequency_sps`, thus allowing the emulation of
real-time operation.
- Improved General Block diagram, both in content and in image resolution.
- The `Custom_UDP_Signal_Source` implementation now accepts
`SignalSource.sample_type=cfloat`, in addition to the existing 4 and 8-bit
length sample types.
