-### v3.6.0 2020 2021-02-09
+### v3.7.1 2021-08-05
+
+- Fix build of `dist` files.
+    + Note: this version ensures the changes from 3.7.0 are actually included in the `dist` files. Thanks to Evan W for reporting. 
+
+### v3.7.0 2021-07-23
+
+- Fix: Use a null prototype object for this.files  (see [#766](https://github.com/Stuk/jszip/pull/766))
+    + This change might break existing code if it uses prototype methods on the `.files` property of a zip object, for example `zip.files.toString()`. This approach is taken to prevent files in the zip overriding object methods that would exist on a normal object.
+
+### v3.6.0 2021-02-09
 
 - Fix: redirect main to dist on browsers (see [#742](https://github.com/Stuk/jszip/pull/742))
 - Fix duplicate require DataLengthProbe, utils (see [#734](https://github.com/Stuk/jszip/pull/734))
 - Fix small error in read_zip.md (see [#703](https://github.com/Stuk/jszip/pull/703))
 
-### v3.5.0 2020 2020-05-31
+### v3.5.0 2020-05-31
 
 - Fix 'End of data reached' error when file extra field is invalid (see [#544](https://github.com/Stuk/jszip/pull/544)).
 - Typescript definitions: Add null to return types of functions that may return null (see [#669](https://github.com/Stuk/jszip/pull/669)).
 - Typescript definitions: Correct nodeStream's type (see [#682](https://github.com/Stuk/jszip/pull/682))
 - Typescript definitions: Add string output type (see [#666](https://github.com/Stuk/jszip/pull/666))
 
-### v3.4.0 2020 2020-04-19
+### v3.4.0 2020-04-19
 
 - Add Typescript type definitions (see [#601](https://github.com/Stuk/jszip/pull/601)).
 
-### v3.3.0 2020 2020-04-1
+### v3.3.0 2020-04-1
 
 - Change browser module resolution to support Angular packager (see [#614](https://github.com/Stuk/jszip/pull/614)).

+   Decode literal, length, and distance codes and write out the resulting
+   literal and match bytes until either not enough input or output is
+   available, an end-of-block is encountered, or a data error is encountered.
+   When large enough input and output buffers are supplied to inflate(), for
+   example, a 16K input buffer and a 64K output buffer, more than 95% of the
+   inflate execution time is spent in this routine.
+
+   Entry assumptions:
+
+        state.mode === LEN
+        strm.avail_in >= 6
+        strm.avail_out >= 258
+        start >= strm.avail_out
+        state.bits < 8
+
+   On return, state.mode is one of:
+
+        LEN -- ran out of enough output space or enough available input
+        TYPE -- reached end of block code, inflate() to interpret next block
+        BAD -- error in block data
+
+   Notes:
+
+    - The maximum input bits used by a length/distance pair is 15 bits for the
+      length code, 5 bits for the length extra, 15 bits for the distance code,
+      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
+      Therefore if strm.avail_in >= 6, then there is enough input to avoid
+      checking for available input while decoding.
+
+    - The maximum bytes that a single length/distance pair can output is 258
+      bytes, which is the maximum length that can be coded.  inflate_fast()
+      requires strm.avail_out >= 258 for each loop to avoid checking for
+      output space.

+   Process a set of code lengths to create a canonical Huffman code.  The

+   for codes with equal lengths.  Then the code starts with all zero bits
+   for the first code of the shortest length, and the codes are integer
+   increments for the same length, and zeros are appended as the length
+   increases.  For the deflate format, these bits are stored backwards
+   from their more natural integer increment ordering, and so when the
+   decoding tables are built in the large loop below, the integer codes
+   are incremented backwards.
+
+   This routine assumes, but does not check, that all of the entries in
+   lens[] are in the range 0..MAXBITS.  The caller must assure this.
+   1..MAXBITS is interpreted as that code length.  zero means that that
+   symbol does not occur in this code.
+
+   The codes are sorted by computing a count of codes for each length,
+   creating from that a table of starting indices for each length in the
+   sorted table, and then entering the symbols in order in the sorted
+   table.  The sorted table is work[], with that space being provided by
+   the caller.
+
+   The length counts are used for other purposes as well, i.e. finding
+   the minimum and maximum length codes, determining if there are any
+   codes at all, checking for a valid set of lengths, and looking ahead
+   at length counts to determine sub-table sizes when building the

 This file will include all API breakage, new features, and upgrade info in
 localForage's lifetime.
 
+### [1.10.0](https://github.com/localForage/localForage/releases/tag/1.10.0)
+
+* Avoid uncaught error in `dropInstance`. You can now catch errors thrown by `dropInstance`, see #807.
+
 ### [1.9.0](https://github.com/mozilla/localForage/releases/tag/1.9.0)
 
 * Fixed TypeScript definition for `getItem`. It now notes that `getItem` can return `null`, so this change may cause TypeScript code that didn't account for `null` values to fail. See #980.

-      Returns a promise that is fulfilled when all the given promises have been

-      is fulfilled with an array that gives all the values in the order they were
-      passed in the `promises` array argument.
-
-      Example:
-
-      ```javascript
-      var promise1 = RSVP.resolve(1);
-      var promise2 = RSVP.resolve(2);

-
-      If any of the `promises` given to `RSVP.all` are rejected, the first promise
-      that is rejected will be given as an argument to the returned promises's

-

-      `RSVP.race` allows you to watch a series of promises and act as soon as the
-      first promise given to the `promises` argument fulfills or rejects.
-
-      Example:
-
-      ```javascript
-      var promise1 = new RSVP.Promise(function(resolve, reject){
-        setTimeout(function(){
-          resolve("promise 1");
-        }, 200);

-
-      var promise2 = new RSVP.Promise(function(resolve, reject){
-        setTimeout(function(){
-          resolve("promise 2");
-        }, 100);
-      });
-
-      RSVP.race([promise1, promise2]).then(function(result){
-        // result === "promise 2" because it was resolved before promise1
-        // was resolved.
-      });
-      ```
-
-      `RSVP.race` is deterministic in that only the state of the first completed
-      promise matters. For example, even if other promises given to the `promises`
-      array argument are resolved, but the first completed promise has become
-      rejected before the other promises became fulfilled, the returned promise
-      will become rejected:
-
-      ```javascript
-      var promise1 = new RSVP.Promise(function(resolve, reject){
-        setTimeout(function(){
-          resolve("promise 1");
-        }, 200);
-      });
-
-      var promise2 = new RSVP.Promise(function(resolve, reject){
-        setTimeout(function(){
-          reject(new Error("promise 2"));
-        }, 100);
-      });
-
-      RSVP.race([promise1, promise2]).then(function(result){
-        // Code here never runs because there are rejected promises!
-      }, function(reason){
-        // reason.message === "promise2" because promise 2 became rejected before
-        // promise 1 became fulfilled
-      });
-      ```
-
-      @method race
-      @for RSVP
-      @param {Array} promises array of promises to observe
-      @param {String} label optional string for describing the promise returned.
-      Useful for tooling.
-      @return {Promise} a promise that becomes fulfilled with the value the first
-      completed promises is resolved with if the first completed promise was
-      fulfilled, or rejected with the reason that the first completed promise
-      was rejected with.

-# 3.0.0 / 2016-07-31
-
-## :boom: Breaking Changes
-
-- :warning: Due to the increasing difficulty of applying security patches made within its dependency tree, as well as looming incompatibilities with Node.js v7.0, **Mocha no longer supports Node.js v0.8**.
-- :warning: **Mocha may no longer be installed by versions of `npm` less than `1.4.0`.**  Previously, this requirement only affected Mocha's development dependencies.  In short, this allows Mocha to depend on packages which have dependencies fixed to major versions (`^`).
-- `.only()` is no longer "fuzzy", can be used multiple times, and generally just works like you think it should. :joy:
-- To avoid common bugs, when a test injects a callback function (suggesting asynchronous execution), calls it, *and* returns a `Promise`, Mocha will now throw an exception:
-
-  ```js
-  const assert = require('assert');
-
-  it('should complete this test', function (done) {
-    return new Promise(function (resolve) {
-      assert.ok(true);
-      resolve();
-    })
-      .then(done);
-  });
-  ```
-
-  The above test will fail with `Error: Resolution method is overspecified. Specify a callback *or* return a Promise; not both.`.
-- When a test timeout value *greater than* `2147483648` is specified in any context (`--timeout`, `mocha.setup()`, per-suite, per-test, etc.), the timeout will be *disabled* and the test(s) will be allowed to run indefinitely.  This is equivalent to specifying a timeout value of `0`.  See [MDN](https://developer.mozilla.org/docs/Web/API/WindowTimers/setTimeout#Maximum_delay_value) for reasoning.
-- The `dot` reporter now uses more visually distinctive characters when indicating "pending" and "failed" tests.
-- Mocha no longer supports [component](https://www.npmjs.com/package/component).
-- The long-forsaken `HTMLCov` and `JSONCov` reporters--and any relationship to the "node-jscoverage" project--have been removed.
-- `spec` reporter now omits leading carriage returns (`\r`) in non-TTY environment.
-
-## :tada: Enhancements
-
-- [#808]: Allow regular-expression-like strings in `--grep` and browser's `grep` querystring; enables flags such as `i` for case-insensitive matches and `u` for unicode. ([@a8m])
-- [#2000]: Use distinctive characters in `dot` reporter; `,` will denote a "pending" test and `!` will denote a "failing" test. ([@elliottcable])
-- [#1632]: Throw a useful exception when a suite or test lacks a title. ([@a8m])
-- [#1481]: Better `.only()` behavior. ([@a8m])
-- [#2334]: Allow `this.skip()` in async tests and hooks. ([@boneskull])
-- [#1320]: Throw a useful exception when test resolution method is overspecified. ([@jugglinmike])
-- [#2364]: Support `--preserve-symlinks`. ([@rosswarren])
-
-## :bug: Bug Fixes
-
-- [#2259]: Restore ES3 compatibility.  Specifically, support an environment lacking `Date.prototype.toISOString()`, `JSON`, or has a non-standard implementation of `JSON`. ([@ndhoule], [@boneskull])
-- [#2286]: Fix `after()` failing to execute if test skipped using `this.skip()` in `beforeEach()`; no longer marks the entire suite as "pending". ([@dasilvacontin], [@boneskull])
-- [#2208]: Fix function name display in `markdown` and `html` (browser) reporters. ([@ScottFreeCode])
-- [#2299]: Fix progress bar in `html` (browser) reporter. ([@AviVahl])
-- [#2307]: Fix `doc` reporter crashing when test fails. ([@jleyba])
-- [#2323]: Ensure browser entry point (`browser-entry.js`) is published to npm (for use with bundlers).  ([@boneskull])
-- [#2310]: Ensure custom reporter with an absolute path works in Windows. ([@silentcloud])
-- [#2311]: Fix problem wherein calling `this.slow()` without a value would blast any previously set value. ([@boneskull])
-- [#1813]: Ensure Mocha's own test suite will run in Windows. ([@tswaters], [@TimothyGu], [@boneskull])
-- [#2317]: Ensure all interfaces are displayed in `--help` on CLI.  ([@ScottFreeCode])
-- [#1644]: Don't exhibit undefined behavior when calling `this.timeout()` with very large values ([@callumacrae], [@boneskull])
-- [#2361]: Don't truncate name of thrown anonymous exception. ([@boneskull])
-- [#2367]: Fix invalid CSS. ([@bensontrent])
-- [#2401]: Remove carriage return before each test line in spec reporter. ([@Munter])
-
-## :nut_and_bolt: Other
-
-- Upgrade production dependencies to address security advisories (and because now we can): `glob`, `commander`, `escape-string-regexp`,
-and `supports-color`. ([@boneskull], [@RobLoach])
-- Add Windows to CI. ([@boneskull], [@TimothyGu])
-- Ensure appropriate `engines` field in `package.json`. ([@shinnn], [@boneskull])
-- [#2348]: Upgrade ESLint to v2 ([@anthony-redfox])

-# 2.5.0 / 2016-05-23
-
-> This has been awhile coming!  We needed to feel confident that the next release wouldn't break browser compatibility (e.g. the last few patch releases).
->
-> ### Browser Tests in CI
->
-> We now run unit tests against PhantomJS v1.x and an assortment of browsers on [SauceLabs](https://saucelabs.com), including:
-> - Internet Explorer v8.0
-> - Chrome (latest)
-> - Firefox (latest)
-> - Safari (latest)
-> - Microsoft Edge (latest)
->
-> To accomplish this, we now run Mocha's unit tests (and a handful of integration tests) via [Karma](https://npmjs.com/package/karma) and a modified [karma-mocha](https://npmjs.com/package/karma-mocha).  Along the way, we had to solve issue [#880] (apologies to @mderijcke and @sukima who had PRs addressing this), as well as replace most usages of [should](https://npmjs.com/package/should) with [expect.js](https://npmjs.com/package/expect.js) for IE8.
->
-> Going forward, when sending PRs, your code will *only* run against PhantomJS v1.x (and not hit SauceLabs) [because security](https://docs.travis-ci.com/user/pull-requests/#Security-Restrictions-when-testing-Pull-Requests).
->
-> ### Node.js 6.x
-> Node.js 6.x "just worked" before, but now it's in the CI matrix, so it's "officially" supported.  Mocha *still retains support* for Node.js 0.8.x.
->
-> ### "Minor" Release
-> You'll see mostly bug fixes below, but also a couple features--as such, it's a "minor" release.
->
-> ### TYVM
->
-> Thanks to everyone who contributed, and our fabulous [sponsors and backers](https://opencollective.com/mochajs)!

-# Contributing to Mocha
-
-> Please read these guidelines before submitting an issue, filing a feature request, or contributing code.
-
-## :question: Got a Question?
-
-If you have a question about using Mocha, please use the [mailing list](https://groups.google.com/group/mochajs), [StackOverflow](https://stackoverflow.com), or ask the friendly people in our [chat room](https://gitter.im/mochajs/mocha).
-
-## :bug: I Found a Bug
-
-Sorry!  It happens to the best of us.  If you've found a bug in Mocha, **please [search](https://github.com/mochajs/mocha/issues/) to see if it's already been reported**.  Otherwise, create a [new issue](https://github.com/mochajs/mocha/issues/new).  If you can fix the bug yourself, feel free to create a [pull request](#propose-a-change) thereafter.
-
-Please include *as much detail as possible* to help us reproduce and diagnose the bug.  Most importantly:
-
-- Let us know *how* you're running Mocha (options, flags, environment, browser or Node.js, etc.)
-- Include your test code or file(s).  If large, please provide a link to a repository or [gist](https://gist.github.com).
-- Please show code in JavaScript only (any version)
-
-If we need more information from you, we'll let you know.  If you don't within a reasonable time frame (TBD), your issue will be automatically closed for inactivity.
-
-## :exclamation: Propose a Change
-
-Before you get your hands dirty, please [search](https://github.com/mochajs/mocha/issues/) for a related issue, or [create a new one](https://github.com/mochajs/mocha/issues/new).  If you wish to contribute a new feature, this is doubly important!  Let's discuss your proposed changes first; we don't want you to waste time implementing a change that is at odds with the project's direction.  That said, we'll happily consider any contribution, no matter how great or small.
-
-*This paragraph would contain information about Mocha's roadmap, but it doesn't yet exist.* :poop:
-
-It's also important to understand some overarching goals of Mocha, detailed below.
-
-### :soccer: About Project Goals
-
-Mocha is a test framework.  Developers use it against anything from legacy spaghetti in IE7 to stage-0 TC39 features in Electron.  While still staying current, Mocha will only drop support for old platforms as a last resort.  If and only if Mocha cannot move forward as a project, support will be dropped.  If workarounds exist, they are preferred.
-
-Mocha adheres strictly to [semantic versioning](https://semver.org).  We are *extremely cautious* with changes that have the potential to break; given the size of Mocha's user base, it's *highly unlikely* a breaking change will slide by.
-
-Mocha's usage far outweighs its resources.  If a proposed feature would incur a maintenance penalty, it could be a hard sell.
-
-We ask you please keep these goals in mind when making or proposing changes.
-
-### :shoe: Contributing Code: Step-by-Step
-
-Follow these steps to get going.  If you are having trouble, don't be afraid to [ask for help](#got-a-question).
-
-1.  [Install Node.js 4.x or newer](https://nodejs.org/download).
-1.  Install [GNU Make](https://www.gnu.org/software/make/) or equivalent.
-1.  Follow [Github's documentation](https://help.github.com/articles/fork-a-repo/) on setting up Git, forking and cloning.
-1.  Create a new branch in your working copy.  Give your branch a descriptive name, such as `issue/12345`: `git checkout -b issue/12345`.
-1.  Execute `npm install` to install the development dependencies.
-1.  Make your changes and add them via `git add`.
-  - **Do not modify** the root `mocha.js` file directly; it is automatically generated.
-  - Your changes will likely be somewhere in `lib/`, `bin/` or `browser-entry.js` if your changes are browser-specific.
-  - Please add unit and/or integration tests (depending on the nature of your changes).
-  - Keep your PR focused.  Don't fix two things at once, or make formatting changes alongside bug fixes.
-1.  Before committing, run `npm test`.
-  - This will run unit tests, Node.js and browser integration tests, and lint the source code.
-  - The "browser" tests use Mocha to test itself; it will rebuild the root `mocha.js` file with your changes.
-  - **Please avoid committing changes to `mocha.js`**.
-  - Ultimately, your pull request will be built on our continuous integration servers ([Travis CI](https://travis-ci.org/mochajs/mocha) and [AppVeyor](https://ci.appveyor.com/project/boneskull/mocha)).  The first step to ensuring these checks pass is to test on your own machine.
-1.  Commit your changes.
-  - Use a brief message on the first line, referencing a relevant issue (e.g. `#12345`).
-  - Add detail in subsequent lines.
-1.  Push your changes to your fork.
-1.  Navigate to the source repository.  You should see a notification about your recent changes in your fork's branch, with a button to create a pull request.  Click it.
-1.  Describe your changes in detail here.  Once you're satisfied, submit the form.
-  - *PRO TIP*: If you've used a multi-line commit message, Github will pre-fill the PR's description with it.
-1.  If you have not signed our Contributor License Agreement, a friendly robot will prompt you to do so.  A CLA (electronic) signature is **required** for all contributions of code to Mocha.
-1.  CI will run against your changes.
-  - If the changes fail the checks, you will need to address those before merging.
-  - You don't need to make a new PR to make changes.  Instead, commit on top of your changes, and push these to your fork's branch.  The PR will be updated, and CI will re-run.
-  - Github will indicate if there's a conflict.  If this happens, you will need to [rebase](https://help.github.com/articles/about-git-rebase/) your branch onto the `master` branch of the source repository.  *Don't merge.*
-  - It's no longer necessary to "squash" your changes.
-1.  Be patient while your PR is reviewed.  This can take awhile ([why?](https://github.com/orgs/mochajs/projects/4)).  We may request changes; don't be afraid to question them.
-
-## :angel: I Just Want To Help
-
-*Excellent.*  Here's how:
-
-- **Handy with JavaScript?**  Please check out the issues labeled [`pr-please`](https://git.io/vXYu2).
-- **Can you write good (and do other stuff good too)?**  Help with the documentation.  See the [issues for our site](https://github.com/mochajs/mochajs.github.io/issues).
-- **Design your thing?**  [Our site](https://github.com/mochajs/mochajs.github.io) needs your magic touch.
-- **Know Mocha's codebase?**  We could use your help triaging issues and/or reviewing pull requests.  Please contact an [org member](https://github.com/orgs/mochajs/people), and we'll chat.
-- **Want to build our community?**  Mocha has a *lot* of users.  We could use your help bringing everyone together in peace and harmony.  Please contact an [org member](https://github.com/mochajs/people).
-- **You can sell dirt to worms?**  Let's raise Mocha's profile in the JavaScript and OSS communities.  Please contact an [org member](https://github.com/mochajs/people)!
-- **Wait--you write unit tests for *fun*?**  A PR which increases coverage is unlikely to be turned down.
-- **Are you experienced?**  If you're a seasoned Mocha user, why not help answer some questions in the [chat room](https://gitter.im/mochajs/mocha)?

- * JsDiff.diffChars: Character by character diff
- * JsDiff.diffWords: Word (as defined by \b regex) diff which ignores whitespace
- * JsDiff.diffLines: Line based diff
- *
- * JsDiff.diffCss: Diff targeted at CSS content
- *
- * These methods are based on the implementation proposed in

-// a transform stream is a readable/writable stream where you do
-// something with the data.  Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored.  (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation.  For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up.  When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer.  When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks.  If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk.  However,
-// a pathological inflate type of transform can cause excessive buffering
-// here.  For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output.  In this case, you could write a very small
-// amount of input, and end up with a very large amount of output.  In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform.  A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.

-Modernizr [![Build Status](https://secure.travis-ci.org/Modernizr/Modernizr.png?branch=master)](http://travis-ci.org/Modernizr/Modernizr)
-=========
-
-### a JavaScript library allowing you to use CSS3 & HTML5 while maintaining control over unsupported browsers 
-
-Modernizr tests which native CSS3 and HTML5 features are available in
-the current UA and makes the results available to you in two ways:
-as properties on a global `Modernizr` object, and as classes on the
-`<html>` element. This information allows you to progressively enhance
-your pages with a granular level of control over the experience.
-
-Modernizr has an optional (*not included*) conditional resource loader
-called `Modernizr.load()`, based on Yepnope.js ([yepnopejs.com](http://yepnopejs.com/)).
-To get a build that includes `Modernizr.load()`, as well as choosing
-which tests to include, go to [www.modernizr.com/download/](http://www.modernizr.com/download/)
