## V1.5.3 April 2021
1. Simultaneous decode of 2020, 1600 and 700C/D/E (without needing to push Stop first, change the mode and push Start again).
2. Dynamic switching of the current Tx mode between the aforementioned modes, again without needing to restart the session.
3. A Tx level slider on the right hand side of the main screen to fine-tune transmit output (to more easily avoid clipping ALC and conflicting with other soundcard ham radio applications).
## V1.5.2 January 2021
1. Updates storage for sound card configuration to use device names instead of IDs.
2. Detects changes to computer sound card configuration and notifies user when devices go away.
## V1.5.1 January 2021
1. Experimental support for reporting to [PSK Reporter](https://pskreporter.info) added.
2. Bug fixes with audio configuration to allow mono devices to be used along with stereo ones.
3. Tweaks to user interface and record/playback functionality to improve usability.
4. Bug fixes and tweaks to improve voice keyer support.
## V1.5.0 December 2020
1. FreeDV 700E, better performance than 700D on fast fading channels
1. FreeDV 700D/700E clipper to increase average transmit power by 6dB
## V1.4.3 August 2020
1. Maintenance Release (no major new features)
1. Changes to support wxWidgets 3.1 (but Windows versions built against wxWidgets 3.0)
1. Under the hood - OFDM modem has been refactored, shouldn't affect freedv-gui operation
## V1.4.2 July 2020
1. Maintenance Release (no major new features)
1. Improved squelch/audio pass through on 700D/2020/2400B
1. Under the hood - Codec2 library has been refactored, shouldn't affect freedv-gui operation
1. Removed Project Horus support (now being maintained outside of Codec2/FreeDV)
## V1.4 June-October 2019
1. FreeDV 2020, Project Horus Binary Modes.
1. [Improved OFDM Modem Acquisition](http://www.rowetel.com/?p=6824), this will improve sync time on FreeDV 700D and 2020 on HF fading channels, and can also handle +/- 60 Hz frequency offsets when tuning.
1. Fixed FreeDV 700C frequency offset bug fix, was losing sync at certain frequency offsets.
1. Wide bandwidth phase estimation and DPSK for OFDM modes (700D/2020) for fast fading/QO-100 channels (Tools-Options)
1. Better speech quality on FreeDV 700C/700D with Auto equaliser (Tools-Filter)
## V1.3 May 2018
* FreeDV 700D
