+
+The New API in 0.9
+==================
+
+The current version, 0.9, deprecates the older API that exported several functions: `strftimeTZ`, `strftimeUTC`, and `localizedStrftime`. In addition to this the exported function referenced itself as `require('strftime').strftime` or `window.strftime.strftime` for consistency with the other functions. *These functions are deprecated in 0.9 and will be removed in 1.0.*
+
+Now you only need the single object exported and you can create a specialized version of it using the functions `utc()`, `localize(locale)`, and `timezone(offset)`. You can no longer pass in a timezone or locale on each call to `strftime` which is a regression. If you need this let me know and we will add it back into the API.

-    console.log(strftime_IT('%B %d, %Y %H:%M:%S')) // aprile 28, 2011 18:21:08
