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. - 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
- The runtime version has been increased. Precompiled templates will need to use runtime of at least 4.0.0.

Compatibility notes:
- Runtime breaking changes. Must match 3.x runtime and precompiler.
- The AST has been upgraded to a public API.
- There are a number of changes to this, but the format is now documented in docs/compiler-api.md
- The Visitor API has been expanded to support mutation and provide a base implementation
- The
JavaScriptCompiler
APIs have been formalized and documented. As part of the sourcemap handling these should be updated to return arrays for concatenation. JavaScriptCompiler.namespace
has been removed as it was unused.SafeString
is now duck typed ontoHTML
New Features:
- noConflict
- Source Maps
- Block Params
- Strict Mode
- @last and other each changes
- Chained else blocks
- @data methods can now have helper parameters passed to them

Compatibility notes:
- The default build now outputs a generic UMD wrapper. This should be transparent change but may cause issues in some environments.
- 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.
programWithDepth
has been removed an instead an array of context values is passed to fields needing depth lookups.
false
values are now printed to output rather than silently dropped- 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.
- Partials that are standalone will now indent their rendered content
AST.ProgramNode
's signature has changed.- Numerious methods/features removed from psuedo-API classes
JavaScriptCompiler.register
JavaScriptCompiler.replaceStack
no longer supports non-inline replaceCompiler.disassemble
DECLARE
opcodestrip
opcodelookup
opcode- Content nodes may have their
string
values mutated over time.original
field provides the unmodified value.

- Make JSON a requirement for the compiler. - 058c0fb
- Temporarily kill the AWS publish CI step - 8347ee2
Compatibility notes:
- A JSON polyfill is required to run the compiler under IE8 and below. It's recommended that the precompiler be used in lieu of running the compiler on these legacy environments.

helperMissing
helper no longer has the indexed name argument. Helper name is now available viaoptions.name
.- Precompiler output has changed, which breaks compatibility with prior versions of the runtime and precompiled output.
JavaScriptCompiler.compilerInfo
now returns generic objects rather than javascript source.- AST changes
- INTEGER -> NUMBER
- Additional PartialNode hash parameter
- New RawBlockNode type
- Data frames now have a
_parent

Compatibility notes:
- The project now includes separate artifacts for AMD, CommonJS, and global objects.
- AMD: Users may load the bundled
handlebars.amd.js
orhandlebars.runtime.amd.js
files or load individual modules directly. AMD users should also note that the handlebars object is exposed via thedefault
field on the imported object. This gist provides some discussion of possible compatibility shims. - CommonJS/Node: Node loading occurs as normal via
require
- Globals: The
handlebars.js
andhandlebars.runtime.js
files should behave in the same manner as the v1.0.12 / 1.0.0 release.
- AMD: Users may load the bundled
- Build artifacts have been removed from the repository. npm, components/handlebars.js, cdnjs, or the 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.

- #437 - Require matching brace counts in escaped expressions
- Merge passed partials and helpers with global namespace values
- Add support for complex ids in @data references
- Docs updates
Compatibility notes:
- 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. - The compiler version has changed. Precompiled templates with 1.0.12 or higher must use the 1.0.0 or higher runtime.

When upgrading from the Handlebars 0.9 series, be aware that the signature for passing custom helpers or partials to templates has changed.
Instead of:
template(context, helpers, partials, [data])
Use:
template(context, {helpers: helpers, partials: partials, data: data})
