This library contains JavaScript implementations of all basic DataValue classes used in the Wikibase software, along with associated parsers and formatters. This library mirrors most of the PHP implementations of DataValue classes as specified in the DataValues set of libraries (most notably the basic, Geo, Number, and Time libraries).

• Removed globeCoordinate.GlobeCoordinate.getDecimal
• Removed getLowerBound, getUpperBound, getAmount from QuantityValue
• Removed support for Node.js versions older than v10

• The library is now a pure JavaScript library.
• Removed MediaWiki ResourceLoader module definitions.
• Removed globeCoordinate.Formatter.
• Removed the globeCoordinate utility class.

• Removed valueFormatters.ValueFormatterStore.
• Removed the options constructor parameter as well as the getOptions method from valueFormatters.ValueFormatter.
• Removed dataValues.DataValue.getSortKey from the interface and all implementations.
• Removed dataValues.TimeValue.getYear, getMonth, getDay, getHour, getMinute, and getSecond.
• Removed globeCoordinate.GlobeCoordinate.iso6709.
• Declared globeCoordinate.GlobeCoordinate.getDecimal private.

• Updated JSDoc tags mistakenly requiring objects.
• Removed an unused dependency on composer/installers.
• Raised required PHP version from 5.3 to 5.5.9.

• QuantityValue now supports unknown upper and lower bounds, required for compatibility with DataValues Number 0.8.0.

• Added 1/10000 of an arcsecond as a known precision to globeCoordinate.Formatter.
• Fixed globeCoordinate.Formatter.PRECISIONTEXT not properly supporting precisions lower than 1/1000 of an arcsecond.

• Added support for undefined precision to globeCoordinate.GlobeCoordinate.
• Added globe support to globeCoordinate.GlobeCoordinate.

• valueParsers.StringParser.parse now resolves empty strings to null.
• Renamed string ids for the 0 to 6 dataValues.TimeValue.PRECISIONS to be identical to the PHP constants in DataValues Time.

• Renamed dataValues.UnUnserializableValue to dataValues.UnDeserializableValue.
• Changed constructor parameter order of dataValues.UnDeserializableValue (formerly dataValues.UnUnserializableValue).
• Removed time.js legacy code, including time.Time and time.Parser. Every "vital" functionality has been ported to dataValues.TimeValue which now may be interacted with directly instead of having to retrieve the encapsulated time.Time object first.
• Removed obsolete valueParsers.TimeParser. Back-end parser is to be used via API.
• Removed obsolete mw.ext.dataValues module as it was just overwriting the obsolete time.js settings. Dependencies should be updated to point directly to the dataValues.values module.

• Implemented toJSON and newFromJSON in dataValues.UnDeserializableValue.
• Consolidated code structure, updated and added code documentation to allow generating a proper documentation using JSDuck.

• Remove explicit resource loader dependency on jquery.qunit.

• Time object's month and day attributes default to 0 instead of 1 now.
• Fixed Time.newFromIso8601().
• Improved PhantomJS Testrunner, outputs failed assertions on the console now.
• Improved globeCoordinate.GlobeCoordinate.equals()

• #40 Removed the arbitrary list of precisions for globe coordinates

• #44 Fixed comparing time values
• #42 Removed 'to a degree' label, now shown as '±1°'
• #45 Removed constructor naming debugging feature

• Remove ResourceLoader dependencies on jquery and mediawiki (bug 69468)

• Don't limit precisions of globe coordinates in the UI (allows display of values with a non predefined precision)

• Renamed ValueFormatterFactory to ValueFormatterStore.
• Renamed ValueParserFactory to ValueParserStore.
• Removed mw.ext.valueFormatters and mw.ext.valueParsers.

• Defined parameters of the promises returned by ValueFormatter's and ValueParser's format/parse functions.

• mw.ext.valueParsers does not register valueParsers.TimeParser anymore
• mw.ext.valueFormatters does not register valueFormatters.StringFormatter anymore
• Renamed ValueFormatterFactory to ValueFormatterStore.
• Renamed ValueParserFactory to ValueParserStore.

• Fixed definitions of ResourceLoader test modules.
• Accept timestamp strings with zeroes as months and days
• Always return a string in time.writeYear and time.writeDay

• Fixed valueParsers ResourceLoader module definition template.

• Renamed "valueFormatters.factory" Resource Loader module to "valueFormatters.ValueFormatterFactory".
• Renamed "valueParsers.factory" Resource Loader module to "valueParsers.ValueParserFactory".
• Removed ValueView dependency from "mw.ext.valueFormatters" module and "mw.ext.valueParsers" module.

• #8 Removed dataValues.util.Notifier
• #10 Renamed dataValues.util.inherit to util.inherit
• #13 Removed vp.GlobeCoordinateParser and vp.QuantityParser
• #15 Removed the ParseValue API module

• #14 Decoupled the QUnit tests from the MediaWiki resource loader
• #16 Have the tests run on TravisCI using PhantomJS
• #18 Provided QUnit test runner using requireJS
