**Breaking Changes**

- RSS target names must now consist of a domain as well as the target
name, e.g. `rss.cnn_news`
- SSE Support has been removed
- Use of ha_key for authentication is deprecated and will be removed
at some point. For now it will still work
- Many Font Awesome Icon names have changed - any custom icons you
have on dashboards will need to be changed to suit - see
[docs](https://appdaemon.readthedocs.io/en/latest/DASHBOARD_CREATION.html#a-note-on-font-awesome-upgrade)
for more detail.

While working through the upgrade it is strongly advised that you clear
your browser cache and force the recompilation of all of your dashboards
to flush out references to old icons. This can be done by manually
removing the `compiled` subdirectory in `conf_dir`, specifying
`recompile-1` in the arguments to the dashboard, or setting the
hadashboard option `dash_compile_on_start` to `1`.

**Features**

- Added Production Mode to disable checking of App config or code
changes
- RSS Feed can now optionally show a description for each story
- Disabling of zooming and double tap zooming on iOs devices is now
optional via the `scaling` dashboard argument
- Exiting from the commandline with ctrl-c will now cleanly terminate
apps
- Sending SIGTERM to an appdaemon process will cause a clean shutdown,
including orderly termination of all apps in dependency order
- Added extra checking for HASS Initialization to prevent a race
condition in which metadata could not be read
- Weather widget adds the ability to change sensors, more dynamic
units, forecast option, icon options, option to show Rain/Snow
depending on precip_type sensor (and change icons), wind icon
rotates according to wind bearing - contributed by [Marcin

**Fixes**

- Fixed a problem in the Docker initialization script
- Fixed an parameter collision for events with a parameter `name` in
