From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Use TerminalConsoleAppender for console improvements
Rewrite console improvements (console colors, tab completion,
persistent input line, ...) using JLine 3.x and TerminalConsoleAppender.
Also uses the new ANSIComponentSerializer to serialize components when
logging them via the ComponentLogger, or when sending messages to the
console, for hex color support.
New features:
- Support console colors for Vanilla commands
- Add console colors for warnings and errors
- Server can now be turned off safely using CTRL + C. JLine catches
the signal and the implementation shuts down the server cleanly.
- Support console colors and persistent input line when running in
IntelliJ IDEA
Other changes:
- Server starts 1-2 seconds faster thanks to optimizations in Log4j
configuration

Subject: [PATCH] Handle plugin prefixes using Log4J configuration
Display logger name in the console for all loggers except the
root logger, Bukkit's logger ("Minecraft") and Minecraft loggers.
Since plugins now use the plugin name as logger name this will
restore the plugin prefixes without having to prepend them manually
to the log messages.
Logger prefixes are shown by default for all loggers except for
the root logger, the Minecraft/Mojang loggers and the Bukkit loggers.
This may cause additional prefixes to be disabled for plugins bypassing
the plugin logger.

Subject: [PATCH] Improve Log4J Configuration / Plugin Loggers
Add full exceptions to log4j to not truncate stack traces
Disable logger prefix for various plugins bypassing the plugin logger
Some plugins bypass the plugin logger and add the plugin prefix
manually to the log message. Since they use other logger names
(e.g. qualified class names) these would now also appear in the
log. Disable the logger prefix for these plugins so the messages
show up correctly.

Subject: [PATCH] Paper Metrics
Removes Spigot's mcstats metrics in favor of a system using bStats
To disable for privacy or other reasons go to the bStats folder in your plugins folder
and edit the config.yml file present there.
Please keep in mind the data collected is anonymous and collection should have no
tangible effect on server performance. The data is used to allow the authors of
PaperMC to track version and platform usage so that we can make better management
decisions on behalf of the project.
