# Changelog

## 1.4.1 - 2019-05-28

Fixed:

- Fix spectral artifacts in output when transmissions ends introduced in v1.4.0.

## 1.4.0 - 2019-05-24

Fixed:

- Fix CAN bitrates below 1000 kbps using the `sys.can.rate` property. The supported rates are 1000, 500, 250, 125, 100, 83.3, and 50 kbps.

- Fix error handling when calling `prop` commands without a group argument or with flags specified after the group.

Changed:

- Renamed the `trace print` command to `trace mask`.

Added:

- Add support for runtime configuration of transmit and receive bitrates through the `tx.rate` and `rx.rate` properties.

- Add support for runtime configuration of receive bandwidth as a percentage of the receive bitrate using the `rx.bw` property. The default of 150% matches previous firmware versions.

- Add `sys.can.promisc` property to select between CSP CAN/CFP promiscuous or masked mode. The default is `true` which enables promiscuous mode as in previous firmware versions.

## 1.3.0 - 2019-03-19

Changed:

- Improved ALC first burst value.

## 1.2.0 - 2018-10-23

Changed:

- Renamed `sys.rs422.rate` to `sys.uart.rate`. The property ID and type are unchanged, so existing code will work without modifications.

Added:

- Added IP stack properties in `sys` group. See `doc/ip.rst` for documentation.

## 1.1.0 - 2018-09-07

Fixed:

- Fix lost TM sensor samples under high-load.

Changed:

- Use BT=0.50 as default. The BT can now be changed between 0.3 and 0.6 in 0.05 steps with the `tx.bt` property.

- Framing format: Add header support for multiplexed IP and CSP packets.

- Framing format: Use CCSDS convolutional code polynomials and dual-basis Reed-Solomon.

- Use CAN as default route instead of RS422/KISS.

- Enable internal MCU watchdog.

Added:

- Add ALC loop. Configurable through the `tx.alc.*` properties. Enabled by default.

- Add calibration properties for VCOs, power sensors and coretemp.

- Add periodic PLL retune every 2 minutes for TX and every 10 minutes for RX.

- Add ground watchdog timer (GWDT) to reset system after 24 hours if not reset. The timeout period is configurable through the sys.gwdt.init value.

- Add `rx.detected` counter for detected frames. This is increased for each frame, even if FEC decode fails.

- Show property state (default, loaded, modified) and flags (no-store, read-only) when listing.

- Add remote shell debug service to execute slash commands via CSP.

- Add `sys.name` property to set system hostname in CSP ident and prompt.

## 1.0.0 - 2018-07-06

Added:

- First released version.
