down if it's not there, now that this plugin always provides it. (see #863)Re-releasing v2.4.0 after discovering that the memory leak is isolated to the [memo-parser],
which is more or less experimental anyway.
Yanked due to critical issue in eslint-module-utils with cache key resulting from #839.

(#586, thanks @fson!)newlines-between: "ignore" to [order] (#519)no-unassigned-import] rule (#529)import/extensions setting] defaults to ['.js']. (#306)import/ignore setting] defaults to nothing, and ambiguous modules are ignored natively. This means importing from CommonJS modules will no longer be reported by [default], [named], or [namespace], regardless of import/ignore. (#270)newline-after-import]: Removed need for an empty line after an inline require call (#570)order]: Default value for newlines-between option is now ignore (#519)imports-first is renamed to [first]. imports-first alias will continue to
exist, but may be removed in a future major release.no-unresolved].

(see #489, thanks @tizmagik)no-extraneous-dependencies], after much bikeshedding. Thanks, @knpwrs! (#527)no-named-as-default-member] Allow default import to have a property named "default" (#507, #508, thanks @jquense for both!)import/parsers setting]: parse some dependencies (i.e. TypeScript!) with a different parser than the ESLint-configured parser. (#503)namespace] exception for get property from namespace import, which are re-export from commonjs module (#499 fixes #416, thanks @wKich)allowComputed option for [namespace] rule. If set to true, won't report
computed member references to namespaces. (see #456)import/extensions setting] is respected in spite of the appearance of imports
in an imported file. (fixes #478, thanks @rhys-vdw)import/external-module-folders setting]: a possibility to configure folders for "external" modules (#444, thanks @zloirock)newline-after-import] exception for switch branches with requires iff parsed as sourceType:'module'.

function expression (e.g. () => require('a') || require('b')). (#441, thanks @ljharb)Symbol dependencies (i.e. for-of loops) due to Node 0.10 polyfill
issue (see #415). Should not make any discernible semantic difference.npm prepublish of 1.10.1.

to be treated as builtin modules (a la path, etc. in Node). (#275 + #365, thanks @sindresorhus for driving)newline-after-import related to the use of switch cases.

(#321, thanks @josh)prefer-default-export] handles export function and export const in same file (#359, thanks @scottnonnenberg)export * from 'foo' now properly ignores a default export from foo, if any.

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)extensions]: fallback to source path for extension enforcement if imported
module is not resolved. Also, never report for builtins (i.e. path). (#296)no-named-as-default-member]: don't crash on rest props. (#281, thanks @SimenB)null to path functions.

Using native Map/Set/Symbol.package.json/files instead of .npmignore for package file inclusion (#228, thanks @mathieudutour)es6-* ponyfills instead of babel-runtimeMajor 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).
import/ignore setting] if
something that looks like an export is detected in the module content.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
[no-unresolved] in isolation, and ~35% total reduction in lint time.
import/cache setting]ignore option to [no-unresolved] 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.namespace]/[no-deprecated]) (#211)namespace] no longer flags modules with only a default export as having no names. (ns.default is valid ES6)stage-0 shared configno-deprecated]no-deprecated]: WIP rule to let you know at lint time if you're using deprecated functions, constants, classes, or modules.import/parser or import/parse-options. Instead, ESLint provides the configured parser + options to the rules, and they use that to parse dependencies.babylon as default import parser (see Breaking)no-commonjs] ruleno-amd] ruleno-require rule. [no-commonjs] is more complete.Unpublished from npm and re-released as 0.13.0. See #170.
import/ignore 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.See GitHub release notes for info on changes for earlier releases.
