2.0.0! - 2016-09-30

Added

• <code>unambiguous</code> rule: report modules that are not unambiguously ES modules.

• Added <code>no-unassigned-import</code> rule (#529)

Breaking

• <code>import/extensions</code> setting defaults to ['.js']. (#306)

Fixed

Changed

• Modified <code>no-nodejs-modules</code> error message to include the module's name (#453, #461)

Fixed

1.11.1 - 2016-07-20

Fixed

1.11.0 - 2016-07-17

Added

• Added an peerDependencies option to <code>no-extraneous-dependencies</code> to allow/forbid peer dependencies (#423, #428, thanks @jfmengels!).

Fixed

1.10.3 - 2016-07-08

Fixed

• removing Symbol dependencies (i.e. for-of loops) due to Node 0.10 polyfill issue (see #415). Should not make any discernible semantic difference.

1.10.2 - 2016-07-04

Fixed

Fixed

1.8.1 - 2016-05-23

Fixed

• export * from 'foo' now properly ignores a default export from foo, if any. (#328/#332, thanks @jkimbo) This impacts all static analysis of imported names. (<code>default</code>, <code>named</code>, <code>namespace</code>, <code>export</code>)
• Make <code>order</code>'s newline-between option handle multiline import statements (#313, thanks @singles)
• Make <code>order</code>'s newline-between option handle not assigned import statements (#313, thanks @singles)

• Added newlines-between option to <code>order</code> rule (#298, thanks @singles)
• add <code>no-mutable-exports</code> rule (#290, thanks @josh)
• <code>import/extensions</code> setting: a list of file extensions to parse as modules and search for exports. If unspecified, all extensions are considered valid (for now). In v2, this will likely default to ['.js', MODULE_EXT]. (#297, to fix #267)

Fixed

• <code>extensions</code>: fallback to source path for extension enforcement if imported module is not resolved. Also, never report for builtins (i.e. path). (#296)

Changed

• <code>imports-first</code> now allows directives (i.e. 'use strict') strictly before any imports (#256, thanks @lemonmade)

Fixed

• <code>named</code> now properly ignores the source module if a name is re-exported from an ignored file (i.e. node_modules). Also improved the reported error. (thanks to @jimbolla for reporting)
• <code>no-named-as-default-member</code> had a crash on destructuring in loops (thanks for heads up from @lemonmade)

1.5.0 - 2016-04-18

Added

• report resolver errors at the top of the linted file
• add <code>no-namespace</code> rule (#239, thanks @singles)
• add <code>no-named-as-default-member</code> rule (#243, thanks @dmnd)

Changed

• Rearranged rule groups in README in preparation for more style guide rules

Removed

• support for Node 0.10, via es6-* ponyfills. Using native Map/Set/Symbol.

1.4.0 - 2016-03-25

Added

• Resolver plugin interface v2: more explicit response format that more clearly covers the found-but-core-module case, where there is no path. Still backwards-compatible with the original version of the resolver spec.
• Resolver documentation

Changed

• using package.json/files instead of .npmignore for package file inclusion (#228, thanks @mathieudutour)
• using es6-* ponyfills instead of babel-runtime

1.3.0 - 2016-03-20

Major perf improvements. Between parsing only once and ignoring gigantic, non-module node_modules, there is very little added time.

My test project takes 17s to lint completely, down from 55s, when using the memoizing parser, and takes only 27s with naked babel-eslint (thus, reparsing local modules).

Added

• This change log (#216)
• Experimental memoizing parser

Fixed

• Huge reduction in execution time by only ignoring <code>import/ignore</code> setting if something that looks like an export is detected in the module content.

1.2.0 - 2016-03-19

Thanks @lencioni for identifying a huge amount of rework in resolve and kicking off a bunch of memoization.

I'm seeing 62% improvement over my normal test codebase when executing only <code>no-unresolved</code> in isolation, and ~35% total reduction in lint time.

Changed

• added caching to core/resolve via #214, configured via <code>import/cache</code> setting

1.1.0 - 2016-03-15

Added

• Added an <code>ignore</code> option to <code>no-unresolved</code> for those pesky files that no resolver can find. (still prefer enhancing the Webpack and Node resolvers to using it, though). See #89 for details.

1.0.4 - 2016-03-11

Changed

• respect hoisting for deep namespaces (<code>namespace</code>/<code>no-deprecated</code>) (#211)

Fixed

• don't crash on self references (#210)
• correct cache behavior in eslint_d for deep namespaces (#200)

1.0.3 - 2016-02-26

Changed

• no-deprecated follows deep namespaces (#191)

Fixed

• <code>namespace</code> no longer flags modules with only a default export as having no names. (ns.default is valid ES6)

1.0.2 - 2016-02-26

Fixed

• don't parse imports with no specifiers (#192)

1.0.1 - 2016-02-25

Fixed

• export stage-0 shared config
• documented <code>no-deprecated</code>
• deep namespaces are traversed regardless of how they get imported (#189)

1.0.0 - 2016-02-24

Added

• <code>no-deprecated</code>: WIP rule to let you know at lint time if you're using deprecated functions, constants, classes, or modules.

Changed

• <code>namespace</code>: support deep namespaces (#119 via #157)

1.0.0-beta.0 - 2016-02-13

Changed

• support for (only) ESLint 2.x
• no longer needs/refers to import/parser or import/parse-options. Instead, ESLint provides the configured parser + options to the rules, and they use that to parse dependencies.

Removed

• babylon as default import parser (see Breaking)

0.13.0 - 2016-02-08

Added

• <code>no-commonjs</code> rule
• <code>no-amd</code> rule

Removed

• Removed vestigial no-require rule. <code>no-commonjs</code> is more complete.

0.12.2 - 2016-02-06 [YANKED]

Unpublished from npm and re-released as 0.13.0. See #170.

0.12.1 - 2015-12-17

Changed

• Broke docs for rules out into individual files.

0.12.0 - 2015-12-14

Changed

• Ignore <code>import/ignore</code> setting if exports are actually found in the parsed module. Does this to support use of jsnext:main in node_modules without the pain of managing an allow list or a nuanced deny list.

0.11.0 - 2015-11-27

Added

• Resolver plugins. Now the linter can read Webpack config, properly follow aliases and ignore externals, dismisses inline loaders, etc. etc.!
