Caution!

Here you will find points of caution when updating Sugar to a new version. Think of it as a pruned Changelog with the most front-facing changes surfaced. If your code breaks on update check here first! Read all the ones that are greater than the version you are migrating from.

Upgrade Script

upgrade.js

When upgrading to a new major version, it's hard to know what changes you will be affected by. This document was meant to help, but now there is also the upgrade script! Just include it immediately after Sugar is loaded, and it will log any method calls that may potentially break!

Drop it in before upgrading to get a general idea of what needs to change, or upgrade and fix as you go!

v2.0.0+

  • Level: Major

    • Callbacks for iterating over object properties are now value first, key second. This includes Object.each (now renamed to Object.forEach), Object.map, Object.every, Object.find, Object.count, Object.none, Object.sum, Object.average, Object.min, Object.max, Object.least, Object.most, and Array#groupBy.
  • Level: Major

    • String#assign is now String#format, and behaves very closely to Python's method of the same name. Tokens are now zero based, and start with {0}. Also, errors will be thrown when tokens cannot be matched. Braces can now be escaped by repeating them. Lastly, multiple objects passed will no longer be merged together. Instead either access with new dot syntax (0.prop) or merge together with Object.merge beforehand.
  • Level: Major

    • Function#fill was renamed to Function#partial. Additionally, it no longer accepts null as a placeholder. Use undefined instead.
  • Level: Major

    • Object.equal is renamed to Object.isEqual in both the static and instance method types.
  • Level: Major

    • Object.extended was removed in favor of chainables. The equivalent is now new Sugar.Object(), however the result will be wrapped in a property called .raw. See the docs for more details.
  • Level: Major

    • Object.merge now takes an options object instead of a list of arguments. The 3rd argument is now "deep" in the options object, and the 4th is "resolve". Resolver functions will now abort the merge (for a single property) if undefined is the return value. To tell the resolver function to continue as normal, return the Sugar global object instead. Any non-undefined value returned by the function will now resolve the conflict completely and will not continue traversing into it when in "deep" mode. To tell the resolver function to continue with the merge, return the Sugar global object instead.
  • Level: Major

    • String#has is now removed in favor of String#includes to be in compliance with the ES6 spec. The ES6 method only accepts a string as input, however Sugar enhances this method to allow regexes (can be opted-out).
  • Level: Major

    • Array#include was removed as it is now identical to Array#add.
  • Level: Major

    • Array#findAll was replaced with Array#filterFromIndex in cases that require a start index. For cases without a start index, simply use native Array#filter. Additionally, the "index" and "loop" arguments now come before the callback.
  • Level: Major

    • Array#each was replaced with Array#forEachFromIndex in cases that require a start index. For cases without a start index, simply use native Array#forEach. Additionally, the "index" and "loop" arguments now come before the callback. For iterating until a return value is passed, use Array#some.
  • Level: Major

    • Array#findFrom and Array#findIndexFrom are now Array#findFromIndex and Array#findIndexFromIndex and exist alongside other "from index" methods with similar naming. Additionally, the "index" and "loop" arguments now come before the callback.
  • Level: Major

    • Object.findAll was replaced with Object.filter, which parallels Array#filter by returning a filtered object.
  • Level: Major

    • Object.each was renamed as Object.forEach to bring it more in line with other object methods. Additionally it no longer allows a return value to break the loop. Use Object.some instead for this functionality.
  • Level: Major

    • String#each was renamed to String#forEach to bring it more in line with other methods.
  • Level: Major

    • Date#utc is now Date#setUTC, and now requires explicitly passing true as the first argument to set the flag to true.
  • Level: Major

    • Date#format shortcuts ("short", "long", "full", etc) have significantly changed. See the docs for the new formats. Tokens f, fff, izotz, and ord, have been replaced with S, SSS, Z, and do to align better with Moment/LDML. Dow and Mon were previously always 3 characters and uppercased. Both of these are now locale dependent, as certain locales may prefer different casing or abbreviation length. Lowercased formats dow and mon are also locale-dependent in length, but always lowercased.
  • Level: Major

    • Array#randomize was renamed to Array#shuffle.
  • Level: Major

    • Array.create now only accepts one argument. See the docs for more details or use ES6 method Array.from instead. Sugar provides this as a polyfill in the default bundle.
  • Level: Major

    • Object.watch was removed. This method was the only part of Sugar that was not 100% compatible in all environments, and was an overly simplistic solution to a difficult problem that others have done better (see discussions around Object.observe and polling). As a quick and dirty solution, this will be made available as a plugin. Also includes Object.unwatch.
  • Level: Major

    • Function#after has changed behavior. Previously it would fire every n times. Now it will fire after n calls. Additionally it will not immediately fire when 0 is passed.
  • Level: Major

    • Array#add is now non-destructive. To append to the array in place, use Array#append.
  • Level: Major

    • Object.toQueryString no longer uses square bracket syntax by default. To enable this pass deep in the options object which is now the second argument to the function. namespace, which was previously the second argument to this method, is now prefix in the same options object.
  • Level: Major

    • Object.fromQueryString now performs "smart" conversion of numerals, booleans, and multiple keys by default. To turn this off, pass smart: false in the options object which is now the second argument to the function. Deep bracket syntax ([] in keys) is now off by defualt but can be enabled with deep on the options object.
  • Level: Major

    • RegExp#addFlag and RegExp#removeFlag are now RegExp#addFlags and RegExp#removeFlags and now work on multiple flags at once.
  • Level: Major

    • Date.past, Date.future, Date.utc.create, Date.utc.past, and Date.utc.future are all deprecated. Instead, pass an options object as the second argument to Date.create with the equivalent properties. For example: Date.create('March', { future: true, fromUTC: true, locale: 'ja' }), etc. Additionally, the utc parameter is now fromUTC and a new parameter setUTC has been added to clear up confusion about what the flag was doing. fromUTC assumes the input to be UTC but the output is a normal Javascript local date. setUTC sets an internal flag which tells Sugar to use utc methods like getUTCHours.
  • Level: Major

    • String#startsWith and String#endsWith are now more in compliance with the ES6 spec. They now no longer accept a RegExp (will throw an error) or a case parameter. If you need to do more complex string checking, use String#match with standard regexes instead. Also minor differences in the way the starting/ending positions are coerced may also be present.
  • Level: Major

    • Object.isNaN was removed in favor of native Number.isNaN, which Sugar provides a polyfill for.
  • Level: Major

    • String#normalize was removed to comply with the ES6 spec. It was also a brute force approach and most likely overkill for most situations. It will be made available as a plugin under the name String#toAscii.
  • Level: Major

    • String#capitalize will now only capitalize the first letter of a string by default. If you want to downcase the rest of the string, pass true for the 1st argument. Capitalizing all words is now the 2nd argument.
  • Level: Major

    • String#add was removed and now exists only as String#insert, which it was mainly providing the basis for.
  • Level: Major

    • Array#all, Array#any, Object.all, and Object.any aliases were removed to align Sugar more with native methods. If needed, these can still easily be aliased with Sugar.Array.alias('all', 'every');.
  • Level: Major

    • String#paragraphs was removed.
  • Level: Moderate

    • Object.keys and Object.values no longer have callbacks as second arguments. Use Object.forEach for iteration over an object's properties.
  • Level: Moderate

    • Number#format no longer accepts arguments for the thousands separator and decimal point. Instead these can now be set globally using Sugar.Number.thousands() and Sugar.Number.decimal(). These will also be respected by Number#abbr, Number#metric, and Number#bytes as well.
  • Level: Moderate

    • Number#bytes now uses powers of 1000 by default instead of powers of 1024. For the old behavior, pass "true" as the 2nd argument (after precision). Further, when using the "binary" flag, units will be standard binary units (KiB, MiB, etc.). For standard units (KB, MB, etc.) pass 'si' for the 3rd argument.
  • Level: Moderate

    • Alphanumeric array options are now defined on the global object Sugar instead of Array itself.
  • Level: Moderate

    • Array#at and String#at now no longer accept enumerated arguments. To get an multiple indexes, pass an array instead.
  • Level: Moderate

    • Array#at and String#at now have their loop argument off by default.
  • Level: Moderate

    • Array natural sort options (AlphanumericSortOrder, AlphanumericSortIgnore, etc) now no longer have Alphanumeric in the name, and are now options that are set by the accessor methods Sugar.Array.getOption and Sugar.Array.setOption. Lastly, AlphanumericSort, which simply exposed Sugar's internal sort algorithm is now sortCollate.
  • Level: Moderate

    • Array#sortBy will now not clone the array by default. This will prevent unnecessary work when it is not needed, however it means that the method is now destructive. Simply use clone or concat on the array first for the old behavior.
  • Level: Moderate

    • Object.select and Object.reject now, when passed an object as a matcher, only check for key existence, not whether values also match or not. To do the "intersect" operation that these methods previously performed, Object.filter, Object.remove, or Object.exclude can instead be used.
  • Level: Moderate

    • Date#reset now requires one unit higher when resetting units based on a string. For example, d.reset('day') will now "reset the day", where it's previous behavior was to shift the date to the beginning of the month. Default is also shifted so no change should be necessary when resetting the time.
  • Level: Moderate

    • Array#subtract, Array#union, and Array#intersect all no longer accept multiple arguments. Simply chain them if more than one argument is needed.
  • Level: Moderate

    • Array#min, Array#max, Array#least, Array#most, Object.min, Object.max, Object.least, Object.most: The all argument is now passed before map as an optional argument. This will always put the function callback as the last argument.
  • Level: Minor

    • Date#relative arguments fn and localeCode are now reversed (localeCode first). As this method was previously accepting localeCode as a single argument anyway, this change will only have have an effect if both arguments are used together.
  • Level: Minor

    • Array#remove and Array#exclude no longer accept enumerated paramters. To remove multiple elements, depending on the type a regex or function may be used. Otherwise the method must be called multiple times.
  • Level: Minor

    • Date.create no longer accepts enumerated parameters (2001, 5, 31, ...). Use the normal date constructor instead.
  • Level: Minor

    • Number#metric now uses a "units" string instead of the "limit" argument, which allows a more flexible, intuitive way to define custom units and min/max ranges. Check the docs for more about this.
  • Level: Minor

    • Date#set now rewinds dates that have accidentally traversed into a new month, such as setting { month: 1 } on January 31st. This behavior was previously only on advance and rewind.
  • Level: Minor

    • Date.SugarNewDate is now Sugar.Date.newDateInternal. This method is always on the Sugar global (not Date).
  • Level: Minor

    • Object.map, Object.each, (now Object.forEach) and Object.size were moved to the Object module from the Array module. If you were using these methods and making custom builds you may have to include the Object module now as well.
  • Level: Minor

    • Date#unitSince (Date#hoursSince, etc) now assumes that the passed in format is UTC if the context date is also flagged as UTC (if you're using setUTC). This behavior can be overriden by passing { fromUTC: false } to these methods.
  • Level: Minor

    • Object.clone now clones both non-enumerable properties if they exist and the attribute accessors "get" and "set".
  • Level: Minor

    • Array#isEmpty now does a simple check if the length is zero. To also check if undefined, null, or NaN are present, use Array#compact first.
  • Level: Minor

    • Object.fromQueryString now returns a plain object. If you want what was previously an extended object, use a chainable on the result with new Sugar.Object().
  • Level: Minor

    • String#stripTags and String#removeTags no longer accept enumerated arguments. Simply pass an array of tags to remove multiple.
  • Level: Minor

    • String#titleize was moved from the Inflections module to String.
  • Level: Minor

    • String.Inflector has been removed from the inflections module in favor of the static methods addAcronym, addPlural, and addHuman.
  • Level: Minor

    • String#upto and String#downto now accept "step", which was previously the third argument, as an optional second argument.
  • Level: Very Minor

    • Array#map, Array#unique, Array#groupBy, Array#min, Array#max, Array#least, Array#most, Array#sortBy: Mapping shortcut strings now accept deep matchers with the dot . token. If you have objects that use . in the keys and are using these methods, be careful as this now makes the methods try to go deep. Pass a function instead to map as before.
  • Level: Very Minor

    • Some minor behavior changes around the way String#removeTags works on malformed html. Unmatched closing tags are removed.
  • Level: Very Minor

    • String#hankaku and String#zenkaku now don't take multiple arguments for modes. Just mix them together in the first argument as a string. See docs for more.

v1.4.1+

  • Level: Minor
    • Object.select and Object.reject now will match values when passed an object. This means that if you pass {foo:'bar'}, it will no longer match if the value of foo in your object is not bar. Previously it would match simply if the key existed.

v1.4.0+

  • Level: Major

    • pad, padLeft, and padRight now pad to the exact character. This means that padLeft(20) will produce a string exactly 20 characters long, instead of adding 20 characters worth of padding to the left side of the string as before. You can use String#repeat for the same effect as the old functionality.
  • Level: Major

    • Object.fromQueryString now does not cast values by default. This means that all values in the resulting object are strings, unless castBoolean is true, which will cast boolean values of "true" and "false" only. Digits are no longer cast to numbers at all. Additionally, the "deep" argument is now removed. Deep parameters will always be parsed if they can be.
  • Level: Major

    • Function#lazy now has different arguments. limit is now the third argument with immediate taking its place as second. Additionally immediate -- which determines whether lazy functions are executed immediately then lock or lock then execute after a timeout -- is now false by default.
  • Level: Major

    • Date range methods eachDay, eachMonth, etc. are deprecated in favor of the syntax every("day"), etc.
  • Level: Major

    • Date range method duration is deprecated in favor of span. Additionally it will add 1 to the duration to include the starting number itself. In effect for date ranges this means that duration will be 1 ms longer.
  • Level: Major

    • Range#step alias was removed. Use Range#every instead.
  • Level: Major

    • Date formatting tokens z and zz are now Z and ZZ. Additionally zzz was removed.
  • Level: Moderate

    • Array#find now works according to the ES6 spec. This means that it will no longer take a fromIndex or loop arguments. Instead, the second argument is the context in which the function matcher will be run. If you need the previous functionality, use Array#findFrom and Array#findIndexFrom instead.
  • Level: Moderate

    • Array.sortBy now performs a natural sort by default. This means numbers (any consecutive numbers, so this will include currency formatting, etc.) will sort as numbers, (2 before 100). If you do not want this behavior, set the flag Array.AlphanumericSortNatural to false.
  • Level: Moderate

    • Object.clone now will error if being called on a user-created class instance or host object (DOM Elements, Events, etc). A number of complex issues tie in here, but in the end it is unreliable to call clone on an object that is not a standard data types as 1) hidden properties cannot be cloned 2) the original arguments to the constructor cannot be known 3) even if they could be known the issue of whether or not the constructor should actually be called again is not clear.
  • Level: Moderate

    • The split argument was removed from String#truncate. For truncating without splitting words, use String#truncateOnWord instead. Argument position is adjusted accordingly.
  • Level: Moderate

    • Class instances are now internally matched by reference only. This means that Object.equal(new Person, new Person) is false. This was in fact the original intended behavior but a bug had not been closed here leading to it not actually being false. Although a case can be made for matching class instances by value, in the end it is too expensive and tricky to distinguish them from host objects, which should never be matched by value. Instead it is better to check for equality of class instances on a unique identifier or the like.
  • Level: Moderate

    • Object.isObject no longer returns true for class instances for the same reasons listed above. This also was intended behavior but was defective.
  • Level: Moderate

    • String#normalize is now deprecated, but still available as a separate script in the lib/plugins directory.
  • Level: Moderate

    • Date ranges are now their own module (the "range" module), and are not dependent on the Date module, and work on numbers and strings as well.
  • Level: Minor

    • Enumerable methods on object will now coerce primitive types. This means that Object.findAll('foo') will now treat 'foo' as new String('foo'). This is reversed from the previous behavior which would error on primitive types and coerce objects to primitive types where possible.
  • Level: Minor

    • String#capitalize passing the all flag now will not capitalize after an apostrophe.
  • Level: Very Minor

    • Date ranges that have an end that is less than the start are now no longer considered invalid, and can be iterated across in exactly the same manner. This means that ranges can now be iterated in reverse and .start and .end are no longer equivalent to .min and .max.
  • Level: Very Minor

    • Removed Number#upto and Number#downto will now work on inverse ranges. In other words (1).downto(5) if represented as an array will now produce [1,2,3,4,5] even though 1 is less than 5 and the operator was "downto". It will also step through the range accordingly.
  • Level: Very Minor

    • Passing a regex to array matching methods like findAll will now match it directly against the element in the array, regardless of whether or not the matched element is a string or not. This makes the logic more straightforward but it also means that it will stringify the element before attempting to match. If, for example, you have instances of classes in the array and the regex is /t/, the /t/ will return true for that element as it will match the stringified "[object Object]" of the instance, which is likely not what you want, so caution is needed here.
  • Level: Very Minor

    • Passing null to .map will now have the same effect as undefined (or no arguments), that is, no mapping will occur. This will apply to any method making use of the internal transformArgument, so Array#min, Array#max, and Array#groupBy are affected as well.
  • Level: Very Minor

    • String#pad/padLeft/padRight will now raise an error on padding to a negative number. Conversely, they will no longer raise an error on undefined/null/NaN.

Note about versions < 1.3.9

Version 1.4.0 improves future-compatibility by ensuring that browser updates do not cause breakages going forward. Upgrading is highly recommended, however as there are also many API changes, this patch was created for older versions. Just drop it in after the main script.

v1.3.9+

  • Level: Major
    • Removed String#namespace.

v1.3.8+

  • Level: Major

    • Renamed Date#getWeek and Date#setWeek to Date#getISOWeek and Date#setISOWeek.
  • Level: Very Minor

    • Object.clone will now preserve a date's internal utc flag when set.

v1.3.7+

  • Level: Major

    • String#startsWith and String#endsWith now accept different arguments to better align them with the Harmony proposal of the same name. The second argument is now the "position" that limits where the string starts/ends, and the "case" flag indicating case sensitivity is now pushed to the 3rd argument.
  • Level: Major

    • Enumerable object methods are now included when using Object.extend() making it that much more dangerous, especially as generic methods like count are now defined on the Object prototype. If you use this method, make sure you are in the habit of using hasOwnProperty when checking for presence inside a hash (probably not a bad idea anyway). Also note that Sugar itself has a number of areas that may exhibit unexpected behavior when this method is applied. Please report if you find any.
  • Level: Moderate

    • Aliases on dates such as daysAgo will now count "past" an integer instead of rounding. This means that Date.create('23 hours ago').daysAgo() will now be 0. There is however a small margin of error (roughly 0.1%) that will trigger a round up, which is higher for months, which have a more vague definition and a higher margin for error.

v1.3.6+

  • Level: Very Minor

    • Float values should be properly parsed in Object.fromQueryString, meaning IP addresses and the like will now parse as strings instead of truncated numbers.
  • Level: Very Minor

    • NaN is no longer true for isOdd.
  • Level: Very Minor

    • Date parsing now only allows a maximum of 59 for minutes and seconds.

v1.3.5+

  • Level: Very Minor
    • Array.create now properly creates arrays from objects.

v1.3.2+

  • Level: Minor
    • Date.create will no longer set the UTC flag on dates created from an ISO string with the "Z" flag. This can be considered a bug introduced in the last release. The "Z" flag indicates that a date is in UTC time, but should not serve as an indication that the date should further be manipulated as UTC, only as a cue when parsing. If you want the date to actually behave as UTC (internally call UTC methods), then you need to explicitly set with Date#utc(true) now.

v1.3.1+

  • Level: Major

    • Array methods that allow fuzzy matching on an object (findAll, filter, some, etc.) as well as unique, intersect, union, and subtract, will now match by reference unless certain conditions are met. Most notably this means that arrays of functions as well as arrays of host objects (DOM elements, etc.) will now only match elements that are strictly true by reference (===). If you are using arrays of host objects or functions (event handlers and the like), use caution upgrading. Other kinds of arrays such as primitives (strings, numbers, etc) as well as object literals and instances of user-defined objects should not be affected.
  • Level: Major

    • Date#toUTC deprecated. Previously, this method would subtract the timezone offset of the date, providing a pseudo-utc date. This was a very primitive way of handling the challenge of manipulating utc dates and had drawbacks such as subsequent date manipulations resetting to a localized time. This is now deprecated in favor of Date#utc, which simply sets an internal flag that will tell Sugar to use utc-based date methods or not. Date#utc will NOT manipulate the time in any way. To create a utc-based date that is set to utc time, a flag has been added to Date#create, and other creation methods like Date#future and Date#past to set the utc flag before parsing out the date.
  • Level: Major

    • Date#setUTC deprecated. Instead, simply set the utc flag using Date#utc or passing true as the third argument to Date#create. After this point, utc-based methods will be used internally, making this method unnecessary.
  • Level: Major

    • Date#setUTCWeek deprecated. Set the utc flag and use Date#setWeek instead.
  • Level: Major

    • Date#getUTCWeek deprecated. Set the utc flag and use Date#getWeek instead.
  • Level: Major

    • Date#setUTCWeekday deprecated. Set the utc flag and use Date#setWeekday instead.
  • Level: Minor

    • Number#times now returns an array which is the collected return values of the function passed.
  • Level: Minor

    • Date#clone will now preserve the utc flag.
  • Level: Minor

    • Array methods matching an empty object {} will now return true instead of false against another empty object.
  • Level: Very Minor

    • Date#setWeekday now returns a timestamp instead of undefined.

v1.3+

  • Level: Major

    • Date locales are now moved into a separate module. This means that now with the default download, setting the date locale to anything other than English will throw an error. If you require locales other than English, please include them from the customize page.
  • Level: Major

    • Array#min, Array#max, Array#least, and Array#most now return a single value instead of an array. If you need to get "all min" or "all max" values, then pass true as the second argument to these methods.
  • Level: Major

    • Array#has is deprecated. Use Array#some or Array#any instead.
  • Level: Major

    • String#toDate is deprecated. Use Date.create instead.
  • Level: Major

    • String#add, String#insert, Array#add, and Array#insert now consider negative indexes to be the same as built-in Array#slice. This means that adding 'd' to 'abc' at index -1 now results in 'abdc' instead of 'abcd'.
  • Level: Major

    • Date parsing is now scoped by locale. Previously setting a locale would add all its formats into a common pool that would match from that point on. Now the locale must be either be set beforehand Date.setLocale('fr') or explicitly passed Date.create('...', 'fr'). The exception to this are numeric formats which are core formats and will parse in any locale.
  • Level: Minor

    • Extended objects that are otherwise identical to non-extended counterparts are now considered equal by Object.equal.
  • Level: Minor

    • Object.isEmpty will now error when passed a non-object. This includes object versions of primitives like strings, numbers, and booleans.
  • Level: Minor

    • Default date output format date.format() now includes the time. Previously this was just the date.
  • Level: Minor

    • Array#groupBy no longer returns extended objects. Use Object.extended on the result if you need this.
  • Level: Minor

    • Unrecognized locale codes will now simply produce an invalid date instead of throwing an error. Likewise, fully qualified locale codes ('it_IT') will fall back to 2 character codes ('it') before giving up.
  • Level: Very Minor

    • Array methods using fuzzy matching (findAll, remove, etc.) now match instances of classes as well as plain objects.
  • Level: Very Minor

    • String#capitalize with the first argument as true (capitalize all words) will now capitalize any letter whose previous letter could not be capitalized. Previously only words after spaces were counted.

v1.2.5+

  • Level: Major

    • String#truncate arguments changed. ellipsis ("..." by default) is now the last argument of four. Second argument is now split which is true by default, so the method will behave like standard truncate methods by default. from added as the third parameter and determines where to truncate. Can be "right" (default), "left", or "middle".
  • Level: Major

    • Function#debounce no longer has an argument wait. Equivalent function is now Function#throttle (no arguments). fn.debounce(100, false) is now fn.throttle(100).
  • Level: Minor

    • Object.isObject now returns true for extended objects.

v1.2.4+

  • Level: Minor

    • Object.equal and its instance method form "equals" is now considered "egal". This means that, for example, new String('w') will NOT be equal to 'w', etc. Previously equal was nearly egal, but not quite, so this should only affect very small edge cases. This now means that Sugar will match Underscore's _.isEqual method 100% of the time with the only exception being custom "isEqual" methods that Underscore checks explicitly.
  • Level: Very Minor

    • Object.merge will now merge properties of non-objects like functions.

v1.2.3+

  • Level: Major

    • String#compare, Number#compare, and Date#compare are deprecated
  • Level: Major

    • Object.merge params are swapped. resolve is now the 4th parameter and deep is now 3rd.
    • When using extended objects, this are now 2nd and 3rd parameters. deep is now false by default.
  • Level: Minor

    • Array#sortBy now exhibits more sensible behavior when sorting on strings.

v1.2.2+

  • Level: Very Minor
    • Extended objects now keep their "Hash" constructor (which is internal) so they no longer have Object as their constructor. If you are doing instanceof checks here this may break (which you shouldn't be doing anyway)

v1.2+

  • Level: Major

    • Array methods now use "fuzzy object matching" when passing an object. As an example, arr.find({ foo: 'bar' }) would previously only match an identical object, now it will match any object whose foo property is bar. Additionally, note that passing regexes and functions will be used to match (regexes match against strings, functions are callbacks that return true/false), not compared directly. This applies to the following array methods: every, some, filter, find, findAll, findIndex, remove, none, count, and exclude.
  • Level: Major

    • Object.sugar renamed to Object.restore. However Object.sugar() equivalent is now Object.extend().
  • Level: Minor

    • Object.merge now also merges undefined properties.

v1.1.2+

  • Level: Minor

    • Function#after will now call a method immediately if the passed value is 0.
  • Level: Very minor

    • Object.isEmpty will now properly report false for primitive types like null and empty strings.

v1.1.1+

  • Level: Major
