v2.1.1

• FIXED Regression that broke simple play/pause usage in certain edge cases (#1101).
• FIXED Loading and unloading multiple Howls with the same src could cause them all to unload (#1103).

• ADDED New global html5PoolSize option that allows setting the default size of the HTML5 Audio object pool (#1008).

Breaking Changes

• If you are directly setting Howler.mobileAutoEnable (it defaults to true), then you should change this to Howler.autoUnlock.
• The new HTML5 Audio object pool shouldn't change anything for 99% of use-cases, but if for whatever reason you don't want to use the pool, you can set html5PoolSize to 0 to bypass using the pool.

• FIXED Audio decoding error wasn't always handled correctly (#1019).
