New

• Update check. Once a day, ActionHealth asks spigotmc.org for the latest version number. A new version is logged in the console, and players with ActionHealth.Update (operators by default) get a message when they join. The request sends no data about the server or its players. Turn it off with Update Check: false.
• Decimal health. Health Decimals: 1 shows 19.5 instead of 19. This applies to {health}, {maxhealth}, {absorption} and {opponentlastdamage}.
• Health colors. {healthcolor} changes the color with the health that is left. The default colors are green from 75%, yellow from 50%, gold from 25% and red below. Set your own in Health Colors.
• Off by default. With Enabled By Default: false, players see no health messages until they turn them on with /actionhealth toggle.
• Command messages in the config. Reload Message and Help Message can now be changed or translated.
• New download sites. ActionHealth is now on Hangar. A Modrinth page is waiting for review. Each release now goes to GitHub, Hangar and Modrinth at the same time.

Fixes

• A mob with less than 1 health showed 0 health while it was still alive. Now it shows at least 1, or the smallest step with decimals.

Config

ActionHealth adds the new options to the end of your config.yml. Their values give the same result as before, except Update Check, which is on.
