Changes in moment 2.3.0

changelog.md

What is new to moment 2.3.0 (relative to 2.2.1)

ATTENTION (may break code) isValid reworked

#1140, #913

Completely new model for computing whether a moment is valid or not. Also added parsing flags to allow checking specific issues during parsing.

.format() now returns Ivalid Date for invalid moments. Read #1140 for more details.

Also added strick mode parsing, which is intolerant to all deviations from the format. #913

ATTENTION (may break code) toString always prints in English

#1139

toString should only be used for development/debugging purposes. If you want a long format in a particular language use .format('LLLL') instead.

ATTENTION (may break code) stricter iso parsing

#1092

Iso format will be used only if string doesn't have extra characters after format.

new languages

• Australian English (en-au)
• Bosnian (bs)
• Uzbek (uz)
• Lithuanian (lt)
• Vietnamese (vn)

parse weekdays, week numbers and week years

#1141

Creating moments from string and format now supports weekday, week, week-year, and the iso variant. The week tokens interpretation only kicks in if neither month nor date-of-month are present in the tokens to prevent conflicting information coming from different tokens.

Parsing tokens:

• e weekday
• d, dd, ddd, dddd locale weekday, for example 'Monday'
• E iso weekday
• w week
• W iso week
• gg, gggg, ggggg week year
• GG, GGGG, GGGGG iso week year

Smart language picker

#1142 fixes #1108 and #1109.

The .lang function accepts an array of languages and tries less specific variants too. Intended to be used with browser provided language preferences.

Added iso duration parsing

#1113

Duration objects can be created using an iso duration string like P2MT3H.

Added parseZone

#1106 fixes #887.

Change moment's timezone based on the input string
