Release notes

Sourced from handlebars's releases.

v4.7.10

• security: Sanitize the source map URL when minifying - f37c599
• security: Iterate lazily in #each and strip whitespace in linear time - 812c226
• security: Escape <!-- and <script in precompiled output - 609d1b1 GHSA-xw65-4hp5-5hc7
• security: Don't trust special properties on context data - ceec388 GHSA-p8wg-vrv2-v86f
• security: Only compile partials that are template strings - c28ee7a
• security: Only dispatch known node types in the Compiler and Visitor - 7d501a5
• security: Validate AST values in the compiler instead of the parser - 703fdcc GHSA-8r5x-fm3f-whwj
• Clarify that --root does not restrict filesystem access - 0fcf25c
• Bump minimist to ^1.2.8 - ea8ed82
• Fix Ruby component publishing documentation - d069c1c
• Fix Composer component definition - 6714e07

Compatibility notes:

• {{#each}} iterates iterables such as Map, Set and generators lazily, like for...of, instead of copying them into an array first. Values added to the iterable while the block renders are now visited too.
