7## v4.0.3 - September 23rd, 2015
8- [#1099](https://github.com/wycats/handlebars.js/issues/1099) - @partial-block is overridden ([@btmorex](https://api.github.com/users/btmorex))
9- [#1093](https://github.com/wycats/handlebars.js/issues/1093) - #each skips iteration on undefined values ([@florianpilz](https://api.github.com/users/florianpilz))
10- [#1092](https://github.com/wycats/handlebars.js/issues/1092) - Square braces in key name ([@distantnative](https://api.github.com/users/distantnative))
11- [#1091](https://github.com/wycats/handlebars.js/pull/1091) - fix typo in release notes ([@nikolas](https://api.github.com/users/nikolas))
12- [#1090](https://github.com/wycats/handlebars.js/pull/1090) - grammar fixes in 4.0.0 release notes ([@nikolas](https://api.github.com/users/nikolas))
13
14Compatibility notes:
15- `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.
16- `]` can now be included in `[]` wrapped identifiers by escaping with `\`. Any `[]` identifiers that include `\` will now have to properly escape these values.

64
65Compatibility notes:
66- 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).
67- 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.
68- AST constructors have been dropped in favor of plain old javascript objects
69- The runtime version has been increased. Precompiled templates will need to use runtime of at least 4.0.0.

176
177Compatibility notes:
178- The default build now outputs a generic UMD wrapper. This should be transparent change but may cause issues in some environments.
179- Runtime compatibility breaks in both directions. Ensure that both compiler and client are upgraded to 2.0.0-beta.1 or higher at the same time.
180 - `programWithDepth` has been removed an instead an array of context values is passed to fields needing depth lookups.
181- `false` values are now printed to output rather than silently dropped
182- Lines containing only block statements and whitespace are now removed. This matches the Mustache spec but may cause issues with code that expects whitespace to exist but would not otherwise.
183- Partials that are standalone will now indent their rendered content
184- `AST.ProgramNode`'s signature has changed.
185- Numerious methods/features removed from psuedo-API classes
186 - `JavaScriptCompiler.register`
187 - `JavaScriptCompiler.replaceStack` no longer supports non-inline replace
188 - `Compiler.disassemble`
189 - `DECLARE` opcode
190 - `strip` opcode
191 - `lookup` opcode
192 - Content nodes may have their `string` values mutated over time. `original` field provides the unmodified value.
193- Removed unused `Handlebars.registerHelper` `inverse` parameter
194- `each` helper requires iterator parameter

245
246Compatibility notes:
247- `helperMissing` helper no longer has the indexed name argument. Helper name is now available via `options.name`.
248- Precompiler output has changed, which breaks compatibility with prior versions of the runtime and precompiled output.
249- `JavaScriptCompiler.compilerInfo` now returns generic objects rather than javascript source.
250- AST changes
251 - INTEGER -> NUMBER
252 - Additional PartialNode hash parameter
253 - New RawBlockNode type
254- Data frames now have a `_parent` field. This is internal but is enumerable for performance/compatibility reasons.

338
339
340Compatibility notes:
341- The project now includes separate artifacts for AMD, CommonJS, and global objects.
342 - 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.
343 - CommonJS/Node: Node loading occurs as normal via `require`
344 - Globals: The `handlebars.js` and `handlebars.runtime.js` files should behave in the same manner as the v1.0.12 / 1.0.0 release.
345- 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.
346- Context-stored helpers are now always passed the `options` hash. Previously no-argument helpers did not have this argument.

362- Add support for complex ids in @data references
363- Docs updates
364
365Compatibility notes:
366- The parser is now stricter on `{{{`, requiring that the end token be `}}}`. Templates that do not
367 follow this convention should add the additional brace value.
368- 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.
369- The compiler version has changed. Precompiled templates with 1.0.12 or higher must use the 1.0.0 or higher runtime.

423## Prior Versions
424
425When upgrading from the Handlebars 0.9 series, be aware that the
426signature for passing custom helpers or partials to templates has
427changed.
428
429Instead of:
430
431```js
432template(context, helpers, partials, [data])
433```
434
435Use:
436
437```js
438template(context, {helpers: helpers, partials: partials, data: data})
439```
