- # Change Log
-
- ## 0.7.3
-
- * Fix a bug where nested uses of `SourceMapConsumer` could result in a
- `TypeError`. [#338](https://github.com/mozilla/source-map/issues/338)
- [#330](https://github.com/mozilla/source-map/issues/330)
- [#319](https://github.com/mozilla/source-map/issues/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][]
-
- [#321]: https://github.com/mozilla/source-map/pull/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.
-
- ## 0.5.5
-
- * 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
-
- * Large performance improvements to source-map serialization. See #228 and #229.
-
- ## 0.5.3
-
- * Do not include unnecessary distribution files. See
- commit ef7006f8d1647e0a83fdc60f04f5a7ca54886f86.
-
- ## 0.5.2
-
- * Include browser distributions of the library in package.json's `files`. See
- issue #212.
-
- ## 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.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 `SourceNode`s 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](bugzil.la/1090768).
-
- * Add the `SourceMapConsumer.prototype.computeColumnSpans` method to compute the
- column span of each mapping.
-
- * Add the `SourceMapConsumer.prototype.allGeneratedPositionsFor` method 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 `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 `SourceNode`s.
- Issue #116.
-
- ## 0.1.34
-
- * Make `SourceNode` work with windows style ("\r\n") newlines. Issue #103.
