Features and fixes
Dark mode
Dark mode can now be enabled for users without the extension. You'll find it at the bottom of your user profile.
Warn if there's an unsaved post
You'll be warned if you try to leave a post page when there's text in the editor. If you like to live dangerously, you can turn this functionality off in your user profile.
Game page
Game descriptions now support BBCode and appear at the top of the page.
Add links to your Games Tavern thread and your profile page to help people introduce themselves before trying to sign up for your game.
Add pictures, videos and styling to make your game page more appealing.
Open/Closed has been renamed to "Open/Closed for applications".
Inviting users to games
You might have seen a few comments in the Game Tavern where GMs said they couldn't invite a specific user to a game because the player name didn't appear in the dropdown.
If the name entered in the Invite textbox exactly matches a username, they now appear at the top of the list for selection.
Thread in breadcrumb
On the advanced posting page, the thread appears at the end of the breadcrumb, so you can open it in a new tab and remember what you're replying to.
ooc in notes
Fixed a bug where ooc in the middle of a note made the rest of the note visible.
Avatars that aren't square
Only BowlOfSpinach requested this and didn't even notice once we'd fixed it. I don't know why we bother (he wrote, sulkily).
Current HP in 5e character sheets
5e characters now have a box for their current HP. Because... yeah... current hit points are a thing.
One player is an allowable option
This site now supports duets.
Game editor
Notes dropdown
Don't enjoy the thrill of spelling bizarre usenames? The notes button now has a dropdown for selecting players - choose "Add Note" once you've made your selection.
Upload to Imgur
If your image isn't already on the internet, this option will ask you to select an image from your computer, upload it, and add the img tag.
New BBCode tags
youtube
Click the "share" link on a YouTube video and put it in a youtube tag for inline videos.
I've seen people use videos for ambient music to play whilst reading the post - I like that (shoutout to AA64 and his smooooth Baldur's Gate noir jazz).
One gotcha. If you want to start from a point in time, the YouTube link will have a "?t=" parameter at the end - you'll need to change that to a "?start=" parameter.
I don't know why YouTube uses a different parameter name for embedded videos. I could convert it in code, but less code means fewer bugs, and that's good too - right?
map
Using On The Fly Battle Maps? The map tag means you can keep all the parameters on separate lines for easy editing. The system will also turn the map image into a link, showing the map in a new tab.
If you're not using OtFBM then this is an img tab that automatically adds a link to view the image in a new tab.
Thanks to everyone for the suggestions and feedback.
