0.7.3

• Fix a bug where nested uses of SourceMapConsumer could result in a TypeError. #338 #330 #319

0.7.2

• Another 3x speed up in SourceMapConsumer. Read about it here: http://fitzgeraldnick.com/2018/02/26/speed-without-wizardry.html

0.7.1

• Updated TypeScript typings. #321

0.7.0

• SourceMapConsumer now uses WebAssembly, and is much faster! Read about it here: https://hacks.mozilla.org/2018/01/oxidizing-source-maps-with-rust-and-webassembly/
• Breaking change: new SourceMapConsumer now returns a Promise object that resolves to the newly constructed SourceMapConsumer instance, rather than returning the new instance immediately.
• Breaking change: when you're done using a SourceMapConsumer instance, you must call SourceMapConsumer.prototype.destroy on it. After calling destroy, you must not use the instance again.
• Breaking change: SourceMapConsumer used to be able to handle lines, columns numbers and source and name indices up to 2^53 - 1 (aka Number.MAX_SAFE_INTEGER). It can now only handle them up to 2^32 - 1.
• Breaking change: The source-map library now uses modern ECMAScript-isms: let, arrow functions, async, etc. Use Babel to compile it down to ECMAScript 5 if you need to support older JavaScript environments.
• Breaking change: Drop support for Node < 8. If you want to support older versions of node, please use v0.6 or below.

0.5.6

• Fix for regression when people were using numbers as names in source maps. See #236.

0.5.0

• Node 0.8 is no longer supported.
• Use webpack instead of dryice for bundling.

• Fix a bug with SourceMapConsumer.prototype.sourceContentFor and sources that explicitly start with the source root. See issue #199.

0.4.4

• Fix an issue where using a SourceMapGenerator after having created a SourceMapConsumer from it via SourceMapConsumer.fromSourceMap failed. See issue #191.
• Fix an issue with where SourceMapGenerator would mistakenly consider different mappings as duplicates of each other and avoid generating them. See issue #192.

0.4.3

• A very large number of performance improvements, particularly when parsing source maps. Collectively about 75% of time shaved off of the source map parsing benchmark!
• Fix a bug in SourceMapConsumer.prototype.allGeneratedPositionsFor and fuzzy searching in the presence of a column option. See issue #177.
• Fix a bug with joining a source and its source root when the source is above the root. See issue #182.
• Add the SourceMapConsumer.prototype.hasContentsOfAllSources method to determine when all sources' contents are inlined into the source map. See issue #190.

0.4.2

• Add an .npmignore file so that the benchmarks aren't pulled down by dependent projects. Issue #169.
• Add an optional column argument to SourceMapConsumer.prototype.allGeneratedPositionsFor and better handle lines with no mappings. Issues #172 and #173.

0.4.1

• Fix accidentally defining a global variable. #170.

0.4.0

• The default direction for fuzzy searching was changed back to its original direction. See #164.
• There is now a bias option you can supply to SourceMapConsumer to control the fuzzy searching direction. See #167.
• About an 8% speed up in parsing source maps. See #159.
• Added a benchmark for parsing and generating source maps.

0.3.0

• Change the default direction that searching for positions fuzzes when there is not an exact match. See #154.
• Support for environments using json2.js for JSON serialization. See #156.

0.2.0

• Support for consuming "indexed" source maps which do not have any remote sections. See pull request #127. This introduces a minor backwards incompatibility if you are monkey patching SourceMapConsumer.prototype methods.

0.1.43

• Performance improvements for SourceMapGenerator and SourceNode. See issue #148 for some discussion and issues #150, #151, and #152 for implementations.

0.1.42

• Fix an issue where SourceNodes from different versions of the source-map library couldn't be used in conjunction with each other. See issue #142.

0.1.41

• Fix a bug with getting the source content of relative sources with a "./" prefix. See issue #145 and Bug 1090768.
• Add the SourceMapConsumer.prototype.computeColumnSpans method to compute the column span of each mapping.

0.1.40

• Performance improvements for parsing source maps in SourceMapConsumer.

0.1.39

• Fix a bug where setting a source's contents to null before any source content had been set before threw a TypeError. See issue #131.

0.1.38

• Fix a bug where finding relative paths from an empty path were creating absolute paths. See issue #129.

0.1.37

0.1.36

• Allow the names mapping property to be an empty string. Issue #121.

0.1.35

• A third optional parameter was added to SourceNode.fromStringWithSourceMap to specify a path that relative sources in the second parameter should be relative to. Issue #105.
• If no file property is given to a SourceMapGenerator, then the resulting source map will no longer have a null file property. The property will simply not exist. Issue #104.
• Fixed a bug where consecutive newlines were ignored in SourceNodes. Issue #116.

0.1.34

• Make SourceNode work with windows style ("\r\n") newlines. Issue #103.
• Fix bug involving source contents and the SourceMapGenerator.prototype.applySourceMap. Issue #100.
