1.6.1

• No user-visible changes.

1.6.0

• Produce better errors when expected tokens are missing before a closing brace.

• Avoid crashing when compiling a non-partial stylesheet that exists on the filesystem next to a partial with the same name.

Command-Line Interface

• Add support for the --watch, which watches for changes in Sass files on the filesystem and ensures that the compiled CSS is up-to-date.

• When using --update, surface errors when an import doesn't exist even if the file containing the import hasn't been modified.

• When compilation fails, delete the output file rather than leaving an outdated version.

1.5.1

• Fix a bug where an absolute Windows path would be considered an input:output pair.

• Forbid custom properties that have no values, like --foo:;, since they're forbidden by the CSS spec.

1.5.0

• Fix a bug where an importer would be passed an incorrectly-resolved URL when handling a relative import.

• Throw an error when an import is ambiguous due to a partial and a non-partial with the same name, or multiple files with different extensions. This matches the standard Sass behavior.

Command-Line Interface

• Add an --interactive flag that supports interactively running Sass expressions (thanks to [Jen Thakar][]!).

1.4.0

• Improve the error message for invalid semicolons in the indented syntax.

• Properly disallow semicolons after declarations in the indented syntax.

Command-Line Interface

• Add support for compiling multiple files at once by writing sass input.scss:output.css. Note that unlike Ruby Sass, this always compiles files by default regardless of when they were modified.

  This syntax also supports compiling entire directories at once. For example, sass templates/stylesheets:public/css compiles all non-partial Sass files in templates/stylesheets to CSS files in public/css.

• Add an --update flag that tells Sass to compile only stylesheets that have been (transitively) modified since the CSS file was generated.

Dart API

• Add Importer.modificationTime() and AsyncImporter.modificationTime() which report the last time a stylesheet was modified.

Node API

• Generate source maps when the sourceMaps option is set to a string and the outFile option is not set.

1.3.2

• Add support for @elseif as an alias of @else if. This is not an intentional feature, so using it will cause a deprecation warning. It will be removed at some point in the future.

1.3.1

Node API

• Fix loading imports relative to stylesheets that were themselves imported though relative include paths.

1.3.0

Command-Line Interface

• Generate source map files by default when writing to disk. This can be disabled by passing --no-source-map.

• Add a --source-map-urls option to control whether the source file URLs in the generated source map are relative or absolute.

• Add an --embed-sources option to embed the contents of all source files in the generated source map.

• Add an --embed-source-map option to embed the generated source map as a data: URL in the generated CSS.

Dart API

• Add a sourceMap parameter to compile(), compileString(), compileAsync(), and compileStringAsync(). This takes a callback that's called with a [SingleMapping][] that contains the source map information for the compiled CSS file.

Node API

• Added support for the sourceMap, omitSourceMapUrl, outFile, sourceMapContents, sourceMapEmbed, and sourceMapRoot options to render() and renderSync().

• Fix a bug where passing a relative path to render() or renderSync() would cause relative imports to break.

• Fix a crash when printing warnings in stylesheets compiled using render() or renderSync().

• Fix a bug where format errors were reported badly on Windows.

1.2.1

• Always emit units in compressed mode for 0 dimensions other than lengths and angles.

1.2.0

• The command-line executable will now create the directory for the resulting CSS if that directory doesn't exist.

• Properly parse #{$var} -#{$var} as two separate values in a list rather than one value being subtracted from another.

• Improve the error message for extending compound selectors.
