0.5.6
- Fix for regression when people were using numbers as names in source maps. See #236.
0.5.5
- 
Fix "regression" of unsupported, implementation behavior that half the world happens to have come to depend on. See #235. 
- 
Fix regression involving function hoisting in SpiderMonkey. See #233. 
0.5.4
0.5.3
- Do not include unnecessary distribution files. See commit ef7006f8d1647e0a83fdc60f04f5a7ca54886f86.
0.5.2

0.5.1
- Fix latent bugs in IndexedSourceMapConsumer.prototype._parseMappings. See ff05274becc9e6e1295ed60f3ea090d31d843379.
0.5.0
- 
Node 0.8 is no longer supported. 
- 
Use webpack instead of dryice for bundling. 
- 
Big speedups serializing source maps. See pull request #203. 
- 
Fix a bug with SourceMapConsumer.prototype.sourceContentForand sources that explicitly start with the source root. See issue #199.
0.4.4
- 
Fix an issue where using a SourceMapGeneratorafter having created aSourceMapConsumerfrom it viaSourceMapConsumer.fromSourceMapfailed. See issue #191.
- 
Fix an issue with where SourceMapGeneratorwould 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.allGeneratedPositionsForand 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.hasContentsOfAllSourcesmethod to determine when all sources' contents are inlined into the source map. See issue #190.
0.4.2
- 
Add an .npmignorefile so that the benchmarks aren't pulled down by dependent projects. Issue #169.
- 
Add an optional columnargument toSourceMapConsumer.prototype.allGeneratedPositionsForand 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 biasoption you can supply toSourceMapConsumerto 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.prototypemethods.
0.1.43
- Performance improvements for SourceMapGeneratorandSourceNode. 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.computeColumnSpansmethod to compute the column span of each mapping.
- 
Add the SourceMapConsumer.prototype.allGeneratedPositionsFormethod to find all generated positions associated with a given original source and line.
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
- Fix a bug where if the source root was an empty string, relative source paths would turn into absolute source paths. Issue #124.
0.1.36
- Allow the namesmapping property to be an empty string. Issue #121.
0.1.35
- 
A third optional parameter was added to SourceNode.fromStringWithSourceMapto 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 anullfile 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 SourceNodework with windows style ("\r\n") newlines. Issue #103.
- 
Fix bug involving source contents and the SourceMapGenerator.prototype.applySourceMap. Issue #100.

- 
Fix some edge cases surrounding path joining and URL resolution. 
- 
Add a third parameter for relative path to SourceMapGenerator.prototype.applySourceMap.
- 
Fix issues with mappings and EOLs. 
0.1.32
- 
Fixed a bug where SourceMapConsumer couldn't handle negative relative columns (issue 92). 
- 
Fixed test runner to actually report number of failed tests as its process exit code.

Fixed a typo when reporting bad mappings (issue 87). 
0.1.31

Extend the test runner to allow running single specific test files at a time. 
- 
Performance improvements in SourceNode.prototype.walkandSourceMapConsumer.prototype.eachMapping.
- 
Source map browser builds will now work inside Workers. 
- 
Better error messages when attempting to add an invalid mapping to a SourceMapGenerator.

0.1.27
