v0.7.0

Version 0.7.0

• Changed HTTP POST keys.
• HTML input fileds for IP addresses are now a single text box rather than 4 individual ones.

• Validates HTTP POST data before updating.
• Added HTTP debug flag.
• Fixed crash when configuring device over softap.
• Uses devices name as hostname.
• Prints compiler version used to build.
• Checks libraries/sdk versions at compile-time with user_config macro to disable strict version checking (VERSIONS_ANY = 1).
• Default configuration for DEBUG_CC is now to be disabled for performance issues.
• Does not disable wlan station when connecting to wlan softap if station has a working connection.
• Added pattern checking for ip address input.
• Added HTTP GET handling for non-arduino http server.
• Default HTTP server is now the custom implementation and the old arduino one can be found on port 81.
• Function http_init now returns the http server pcb.
• Error debug messages now has as an [ ERR ] prefix.
• No longer prints wlan channel at boot.
• HTML request time now uses 24h clock.

• Huge improvement to source API documentation.
• Deprecated unused and broken atem_tally_translate function.
• Predefined ATEM command names is now in an enum instead of being macros.

• Fixed arduino/arduino_install not working on linux.

Proxy server

• Proxy server now works with the 0.6.0 reworked source api.

v0.6.0

Firmware

• BREAKING change to configuration layout in memory. (requires reconfiguration)

• Does not crash if unable to connect to SDI shield.

• Does not use BMDSDIControl library anymore.

• SoftAP PSK is not set until first configuration.

• Compilation fails if platform is not supported.

Proxy server

Proxy server currently broken.

v0.5.0

First release. Heavily relies on Arduino for microcontroller code and uses BMDSDIControl library.
Proxy server works but restarts connection to switcher instead of caching data. Windows is untested.
