Specifically, the setLevel(String classOrPackageName, int level) method was public in AbstractLogService, but not part of the LogService API.
This is a backwards incompatible change.
We do the level check in the level-specific methods now, in preparation for the protected log(int level, Object msg, Throwable t) method to become the central override point of concrete implementations. That way, specific implementations will not need to worry about filtering based on level in the typical case.
When logging critical messages (WARN and ERROR levels), use stderr. When logging non-critical messages (e.g., INFO level), use stdout. This change will be very useful for differentiating between different log levels in a simpler way; in particular, ImageJ can send both stdout and stderr to a Console window, coloring stderr messages in red and setting the Console to visible when they occur, but not displaying the Console by default when only stdout messages occur (because many ImageJ plugins spam stdout with lots of debugging output).
