Without these checks, the optimizer webpack plugin would throw when another loader/plugin failed to load a JS module. ## 1.7.3 - 2022-02-16 ### Fixed - Re-added the changelog to the npm package by explicitly listing all relevant files in the package.json. ## 1.7.2 - 2022-01-27 ### Fixed - In some cases, super calls in babel output were not detected and therefore not obfuscated. ## 1.7.1 - 2022-01-24 ### Fixed - Lock @babel/parser to 7.16.8 to avoid performance issues introduced with 7.16.10 ## 1.7.0 - 2022-01-10 ### Fixed - Webpack plugin: detect and disable the [filesystem caching option](https://webpack.js.org/configuration/cache/) (Optimizer does not support it) - Webpack plugin: don't break when [source maps](https://webpack.js.org/configuration/devtool/) are enabled. ## 1.6.1 - 2021-10-20 ### Fixed - Also obfuscate instance fields of babel's safe public class fields output with `obfuscateBabelSafePublicFields` enabled (before, just static fields were considered). ## 1.6.0 - 2021-08-25 ### Added - Support obfuscating babel's safe public class fields output, added the corresponding `obfuscateBabelSafePublicFields` option. - Added TypeScript typings for the optimizer API ### Changed - Add some default obfuscation excludes used by DOM API ## 1.5.0 - 2021-06-25 ### Fixed - Fixed obfuscation of Object.defineProperty declarations ## 1.5.0-beta.1 - 2021-05-25 ### Added - Webpack 5 compatibility ## 1.4.3 - 2020-11-24 ### Changed - Webpack plugin: fix error handling to prevent unhandled promise rejections. - Don't obfuscate short identifiers. - Clarify that the webpack plugin doesn't work with webpack 5, yet. ## 1.4.2 - 2020-08-17 ### Changed - Internal Refactoring ## 1.4.1 - 2020-08-17 ### Fixed - Fixed leftover espree usages ## 1.4.0 - 2020-08-17 ### Changed - Switch to babel libraries for improved modern EcmaScript language feature support - Add some default obfuscation excludes used by popular JS frameworks (Angular, Vue.js) to the webpack plugin. ## 1.3.2 - 2020-06-08 ### Fixed - Fix yjs:keep comments sometimes not respected with node versions before 11 ## 1.3.1 - 2020-06-08 ### Fixed - Fixed compatibility for yFiles for HTML 2.3 class framework features ## 1.3.0 - 2020-05-26 ### Changed - Switched from esprima to espree as the AST parser. This should enable the optimizer to work with code that uses the latest ECMAScript features. ## 1.2.1 - 2020-05-13 ### Added - Add some excludes to the internal blacklist for HTML 2.3 ## 1.2.0 - 2020-05-06 ### Added - Compatibility for yFiles for HTML 2.3 class framework features ## 1.1.0 - 2020-04-28 ### Added - Add the "safeMode" option ## 1.0.7 - 2020-04-07 ### Changed - Update the escodegen dependency to npm so no git is required to use the optimizer. ## 1.0.6 - 2019-12-13 ### Fixed - Added a workaround for compatiblity of the Optimizer webpack plugin with `@angular-devkit/build-angular`versions greater than `0.802.2`. Since version `0.803.0`, the angular plugin resets the compiler host after the first module build, which interferes with the two-pass approach of the Optimizer plugin. As a workaround, the Optimizer plugin now activates webpack's watch mode when an angular webpack plugin is present. This prevents the reset call. ## 1.0.5 - 2019-08-22 ### Fixed - Fix obfuscation of [extra properties in option overloads](https://docs.yworks.com/yfileshtml/#/dguide/framework_option_overloads_extra_properties) ## 1.0.4 - 2019-08-21 ### Added - Fail if an unexpected library file structure is detected ## 1.0.3 - 2019-07-10 ### Added - "shouldOptimize" option for the webpack plugin ## 1.0.2 - 2019-06-13 ### Fixed - In rare cases, the optimizer could break overloaded method access for yFiles API members. ## 1.0.1 - 2019-04-17 ### Added - Ignore option for the webpack plugin ## 1.0.0 - 2019-04-04 ### Added - Plain Javascript Optimizer - Optimizer Webpack Plugin
