-## Linting and Formatting
-
-Handlebars uses `eslint` to enforce best-practices and `prettier` to auto-format files.
-We do linting and formatting in two phases:
-
- Committed files are linted and formatted in a pre-commit hook. In this stage eslint-errors are forbidden,
-  while warnings are allowed.
- The travis-ci job also lints all files and checks if they are formatted correctly. In this stage, warnings
-  are forbidden.
-
-You can use the following scripts to make sure that the travis-job does not fail:
-
- **npm run lint** will run `eslint` and fail on warnings
- **npm run format** will run `prettier` on all files
- **npm run check-before-pull-request** will perform all most checks that travis does in its build-job, excluding the "integration-test".
- **npm run integration-test** will run integration tests (using old NodeJS versions and integrations with webpack, babel and so on)
-  These tests only work on a Linux-machine with `nvm` installed (for running tests in multiple versions of NodeJS).
-
 ## Ember testing

 Differences Between Handlebars.js and Mustache
 ----------------------------------------------
 Handlebars.js adds a couple of additional features to make writing
 templates easier and also changes a tiny detail of how partials work.

- [Nested Paths](https://handlebarsjs.com/guide/expressions.html#path-expressions)
- [Helpers](https://handlebarsjs.com/guide/expressions.html#helpers)
- [Block Expressions](https://handlebarsjs.com/guide/block-helpers.html#basic-blocks)
- [Literal Values](https://handlebarsjs.com/guide/expressions.html#literal-segments)
- [Delimited Comments](https://handlebarsjs.com/guide/#template-comments)
+- [Nested Paths](http://handlebarsjs.com/#paths)
+- [Helpers](http://handlebarsjs.com/#helpers)
+- [Block Expressions](http://handlebarsjs.com/#block-expressions)
+- [Literal Values](http://handlebarsjs.com/#literals)
+- [Delimited Comments](http://handlebarsjs.com/#comments)

 Block expressions have the same syntax as mustache sections but should not be confused with one another. Sections are akin to an implicit `each` or `with` statement depending on the input data and helpers are explicit pieces of code that are free to implement whatever behavior they like. The [mustache spec](http://mustache.github.io/mustache.5.html) defines the exact behavior of sections. In the case of name conflicts, helpers are given priority.

-### Parsing
-
-There are two primary APIs that are used to parse an existing template into the AST:
-
-#### parseWithoutProcessing
-
-`Handlebars.parseWithoutProcessing` is the primary mechanism to turn a raw template string into the Handlebars AST described in this document. No processing is done on the resulting AST which makes this ideal for codemod (for source to source transformation) tooling.
-
-Example:
-
-```js
-let ast = Handlebars.parseWithoutProcessing(myTemplate);
-```
-
-#### parse
-
-`Handlebars.parse` will parse the template with `parseWithoutProcessing` (see above) then it will update the AST to strip extraneous whitespace. The whitespace stripping functionality handles two distinct situations:
-
-* Removes whitespace around dynamic statements that are on a line by themselves (aka "stand alone")
-* Applies "whitespace control" characters (i.e. `~`) by truncating the `ContentStatement` `value` property appropriately (e.g. `\n\n{{~foo}}` would have a `ContentStatement` with a `value` of `''`)
-
-`Handlebars.parse` is used internally by `Handlebars.precompile` and `Handlebars.compile`.
-
-Example:
-
-```js
-let ast = Handlebars.parse(myTemplate);
-```

-[Commits](https://github.com/wycats/handlebars.js/compare/v4.7.0...master)
-
-## v4.7.0 - January 10th, 2020
-
-Features:
-
- feat: default options for controlling proto access - 7af1c12, #1635
-  - This makes it possible to disable the prototype access restrictions added in 4.6.0
-  - an error is logged in the console, if access to prototype properties is attempted and denied
-    and no explicit configuration has taken place.
-
-Compatibility notes:
-
- no compatibilities are expected

-
-## v4.6.0 - January 8th, 2020
-

-
- feat: access control to prototype properties via whitelist (#1633)- d03b6ec
-

-
- fix(runtime.js): partials compile not caching (#1600) - 23d58e7
-

- modernize the build-setup
-  - use prettier to format and eslint to verify - c40d9f3, 8901c28, e97685e, 1f61f21
-  - use nyc instead of istanbul to collect coverage - 164b7ff, 1ebce2b
-  - update build code to use modern javascript and make it cleaner - 14b621c, 1ec1737, 3a5b65e, dde108e, 04b1984, 587e7a3

- chore: try to fix saucelabs credentials (#1627) -
- Update readme.md with updated links (#1620) - edcc84f
-
-BREAKING CHANGES:
-
- access to prototype properties is forbidden completely by default,
-  specific properties or methods can be allow via runtime-options.
-  See #1633 for details.
-  If you are using Handlebars as documented, you should not be accessing prototype
-  properties from your template anyway, so the changes should not be a problem
-  for you. Only the use of undocumented features can break your build.
-
-  That is why we only bump the minor version despite mentioning breaking changes
-
-[Commits](https://github.com/wycats/handlebars.js/compare/v4.5.3...v4.6.0)
-
-## v4.5.3 - November 18th, 2019
-
-Bugfixes:
-
- fix: add "no-prototype-builtins" eslint-rule and fix all occurences - f7f05d7
- fix: add more properties required to be enumerable - 1988878
-
-Chores / Build:
-
- fix: use !== 0 instead of != 0 - c02b05f
- add chai and dirty-chai and sinon, for cleaner test-assertions and spies,
-  deprecate old assertion-methods - 93e284e, 886ba86, 0817dad, 93516a0
-
-Security:
-
- The properties `__proto__`, `__defineGetter__`, `__defineSetter__` and `__lookupGetter__`
-  have been added to the list of "properties that must be enumerable".
-  If a property by that name is found and not enumerable on its parent,
-  it will silently evaluate to `undefined`. This is done in both the compiled template and the "lookup"-helper.
-  This will prevent new Remote-Code-Execution exploits that have been
-  published recently.
-
-Compatibility notes:
-
- Due to the security-fixes. The semantics of the templates using
-  `__proto__`, `__defineGetter__`, `__defineSetter__` and `__lookupGetter__` in the respect that those expression now return
-  `undefined` rather than their actual value from the proto.
- The semantics have not changed in cases where the properties are enumerable, as in:
-
-```js
-{
-  __proto__: 'some string';
-}
-```
-
- The change may be breaking in that respect, but we still only
-  increase the patch-version, because the incompatible use-cases
-  are not intended, undocumented and far less important than fixing
-  Remote-Code-Execution exploits on existing systems.

-## v4.3.0 - September 24th, 2019
-
-Fixes:
-
- Security: Disallow calling "helperMissing" and "blockHelperMissing" directly - 2078c72
- Disallow calling "helperMissing" and "blockHelperMissing" directly - 2078c72
-
-Features:
-
- Add new runtime option `allowCallsToHelperMissing` to allow calling `blockHelperMissing` and `helperMissing`.
-
-Breaking changes:
-
-Compatibility notes:
-
- Compiler revision increased - 06b7224
-
-  - This means that template compiled with versions prior to 4.3.0 will not work with runtimes >= 4.3.0
-    The increase was done because the "helperMissing" and "blockHelperMissing" are now moved from the helpers
-    to the internal "container.hooks" object, so old templates will not be able to call them anymore. We suggest
-    that you always recompile your templates with the latest compiler in your build pipelines.
-
- Disallow calling "helperMissing" and "blockHelperMissing" directly - 2078c72
-  - Calling "helperMissing" and "blockHelperMissing" directly from a template (like in `{{blockHelperMissing}}` was
-    never intended and was part of the exploits that have been revealed early in 2019
-    (see https://github.com/wycats/handlebars.js/issues/1495). _It is also part of a new exploit that
-    is not captured by the earlier fix._ In order to harden Handlebars against such exploits, calling thos helpers
-    is now not possible anymore. _Overriding_ those helpers is still possible.
-  - If you really need this behavior, you can set the runtime option `allowCallsToHelperMissing` to `true` and the
-    calls will again be possible
-
-Both bullet points imly that Handlebars is not 100% percent compatible to 4.2.0, despite the minor version bump.
-
-We consider it more important to resolve a major security issue than to maintain 100% compatibility.

-
-This kind of access is not the intended use of Handlebars and leads to the vulnerability described

-```
-class SomeClass {
-}
-
-SomeClass.staticProperty = 'static'

-var template = Handlebars.compile('{{constructor.staticProperty}}');
-document.getElementById('output').innerHTML = template(new SomeClass());
-// expected: 'static', but now this is empty.

 Compatibility notes:
-
 - `each` iteration with `undefined` values has been restored to the 3.0 behaviors. Helper calls with undefined context values will now execute against an arbitrary empty object to avoid executing against global object in non-strict mode.
 - `]` can now be included in `[]` wrapped identifiers by escaping with `\`. Any `[]` identifiers that include `\` will now have to properly escape these values.

 Compatibility notes:
-
 - Depthed paths are now conditionally pushed on to the stack. If the helper uses the same context, then a new stack is not created. This leads to behavior that better matches expectations for helpers like `if` that do not seem to alter the context. Any instances of `../` in templates will need to be checked for the correct behavior under 4.0.0. In general templates will either reduce the number of `../` instances or leave them as is. See [#1028](https://github.com/wycats/handlebars.js/issues/1028).
 - The `=` character is now HTML escaped. This closes a potential exploit case when using unquoted attributes, i.e. `<div foo={{bar}}>`. In general it's recommended that attributes always be quoted when their values are generated from a mustache to avoid any potential exploit surfaces.
 - AST constructors have been dropped in favor of plain old javascript objects

 - `false` values are now printed to output rather than silently dropped

+Compatibility notes:
+- The project now includes separate artifacts for AMD, CommonJS, and global objects. 
  - AMD: Users may load the bundled `handlebars.amd.js` or `handlebars.runtime.amd.js` files or load individual modules directly. AMD users should also note that the handlebars object is exposed via the `default` field on the imported object. This [gist](https://gist.github.com/wycats/7417be0dc361a69d5916) provides some discussion of possible compatibility shims.
  - CommonJS/Node: Node loading occurs as normal via `require`
  - Globals: The `handlebars.js` and `handlebars.runtime.js` files should behave in the same manner as the v1.0.12 / 1.0.0 release.
- Build artifacts have been removed from the repository. [npm][npm], [components/handlebars.js][components], [cdnjs][cdnjs], or the [builds page][builds-page] should now be used as the source of built artifacts.
+- Build artifacts have been removed from the repository. [npm][npm], [components/handlebars.js][components], [cdnjs][cdnjs], or the [builds page][builds-page] should now be used as the source of built artifacts. 
 - Context-stored helpers are now always passed the `options` hash. Previously no-argument helpers did not have this argument.

 - The parser is now stricter on `{{{`, requiring that the end token be `}}}`. Templates that do not
  follow this convention should add the additional brace value.
 - Code that relies on global the namespace being muted when custom helpers or partials are passed will need to explicitly pass an `undefined` value for any helpers that should not be available.
