 - IRC servers connected to an insecure connection (i.e. the TLS checkbox was not checked when filling the network connect form) now display a warning sign icon and are colored in orange in the channel list. If it is available for this network, you can change this setting by right-clicking on the network name in the channel list, click on "Edit this network...", and update the checkbox (along with the port and sometimes the hostname) before saving the settings again. You will have to disconnect and re-connect to this server.
 - To navigate through windows in the channel list from your keyboard, you must now use <kbd>alt</kbd>+<kbd>↓</kbd> / <kbd>alt</kbd>+<kbd>↑</kbd> in lieu of <kbd>ctrl</kbd>+<kbd>↓</kbd> / <kbd>ctrl</kbd>+<kbd>↑</kbd>, more often used in other chat clients.
-- We have updated our build pipeline to better reflect our browser support. The Lounge now supports [browsers released less than a year ago](http://browserl.ist/?q=last+1+year%2C+firefox+esr) (and [Firefox ESR](https://www.mozilla.org/en-US/firefox/organizations/)), while we used to support the [last 2 versions of all browsers](http://browserl.ist/?q=last+2+versions). In practice, this drops support for some of the least used browsers on mobile (QQ browser, UC browser, Android Browser, Baidu Browser, Blackberry Browser, IE Mobile, Opera Mini, and Opera Mobile), and IE 10/11 on desktop. It however gives slightly more support flexibility for earlier versions of Chrome (62+), Firefox (56+ and ESR), and Opera (48+).
