3.0.1

Changelog

• Fixed a bug wherein FilesystemAdapter::search() was returning every key it contained, instead of just those matching the prefix. Resolves #5 (thanks to @underscore200 for the PR).

3.0.0

Changelog

• Bumped required PHP version to 7.3.
• Added support for using Redis to store Prometheus data.
• Added support for in-memory metric storage (for testing and debugging purposes).
• Added timing utility functions to Histogram (see Histogram::startTimer() and Histogram::time()); requires symfony/stopwatch.

Breaking Changes

• PHP versions before 7.3 are no longer supported.
