A lightweight javascript date library for parsing, validating, manipulating, and formatting dates.
There are a few things being deprecated in the 1.6.0 release.
-
The format tokens
zandzz(timezone abbreviations like EST CST MST etc) will no longer be supported. Due to inconsistent browser support, we are unable to consistently produce this value. See this issue for more background. -
The method
moment.fn.nativeis deprecated in favor ofmoment.fn.toDate. There continue to be issues with Google Closure Compiler throwing errors when usingnative, even in valid instances. -
The way to customize am/pm strings is being changed. This would only affect you if you created a custom language file. For more information, see this issue.
