### v4.0.2
* Added installation instructions.
### v4.0.1
* Fix bugs where `log.progressEnabled` got out of sync with how `gauge` kept
track of these things resulting in a progressbar that couldn't be disabled.
### v4.0.0
* Allow creating log levels that are an empty string or 0.
### v3.1.2
* Update to `gauge@1.6.0` adding support for default values for template
items.
### v3.1.1
* Update to `gauge@1.5.3` to fix to `1.x` compatibility when it comes to
when a progress bar is enabled. In `1.x` if you didn't have a TTY the
progress bar was never shown. In `2.x` it merely defaults to disabled,
but you can enable it explicitly if you still want progress updates.
### v3.1.0
* Update to `gauge@2.5.2`:
* Updates the `signal-exit` dependency which fixes an incompatibility with
the node profiler.
* Uses externalizes its ansi code generation in `console-control-strings`
* Make the default progress bar include the last line printed, colored as it
would be when printing to a tty.
### v3.0.0
* Switch to `gauge@2.0.0`, for better performance, better look.
* Set stderr/stdout blocking if they're tty's, so that we can hide a
progress bar going to stderr and then safely print to stdout. Without
this the two can end up overlapping producing confusing and sometimes
corrupted output.
### v2.0.0
* Make the `error` event non-fatal so that folks can use it as a prefix.
### v1.0.0
* Add progress bar with `gauge@1.1.0`
