• New option: deadCodeInjection. With this option random blocks of dead code will add to the obfuscated code.
• New option: deadCodeInjectionThreshold allows to set percentage of nodes that will affected by deadCodeInjection.
• New option: mangle enables mangling of variable names.
• escapeUnicodeSequence option now disabled by default.
• controlFlowFlattening now affects string literal nodes.

v0.9.3

• Switched from escodegen to escodegen-wallaby, fixed https://github.com/javascript-obfuscator/javascript-obfuscator/pull/50

v0.9.2

• Removed coverage dir from npm package

• Fixed very rare Cannot read property 'type' of undefined error, when RandomGeneratorUtils.getMathRandom() returned incorrect value 1.

v0.9.0-beta.4

• Increased performance

v0.9.0-beta.3

• Breaking change: dropped [email protected] and [email protected] support.
• Switched from npm to yarn internally.

v0.9.0-beta.1

• New option: controlFlowFlattening allows to enable/disable Control Flow flattening. Control flow flattening is a structure transformation of the source code that hinders program comprehension.
• New option: controlFlowFlatteningThreshold allows to set percentage of nodes that will affected by controlFlowFlattening.
• Better es2015 support: correct obfuscation of TemplateLiteral, ArrayPattern, AssignmentPattern nodes.

v0.8.6

• additional fixes for https://github.com/javascript-obfuscator/javascript-obfuscator/issues/29

• fixed https://github.com/javascript-obfuscator/webpack-obfuscator/issues/13

v0.8.3

• selfDefending option now disabled by default.

v0.8.2

• New option seed sets seed for random generator. This is useful for creating repeatable results.
• IE8 runtime error fix.

v0.8.1

• disableConsoleOutput option now replaces console.xxx functions on empty function instead of infinity loop.

v0.8.0

• Breaking options change: unicodeArray option has been renamed to stringArray.
• Breaking options change: unicodeArrayThreshold option has been renamed to stringArrayThreshold.
• Breaking options change: encodeUnicodeArray option has been renamed to stringArrayEncoding and now accepts following values: true|false|'base64'|'rc4'.
• Breaking change: option wrapUnicodeArrayCalls was removed and now all calls to stringArray are always wrapped by special wrapper function.
• New option unicodeEscapeSequence allows to enable/disable strings conversion to unicode escape sequence.
• New option domainLock locks the obfuscated source code so it only runs on specific domains and/or sub-domains.
• New option sourceMapBaseUrl sets base url to the source map import url when sourceMapMode: 'separate'.
• Custom nodes like selfDefendingNode or consoleOutputNode now inserted into deepest stack trace function call.
• Fixed obfuscation of global variables and function names in some cases.
• Fixed wrong obfuscation of labels.
• Rewrite of many custom nodes.

v0.7.3

• CLI missing polyfill fix #17

v0.7.2

• runtime error fix #7

• shorthand object expression fix #16

v0.7.1

• IE error fix #14

v0.7.0-dev.3

• Obfuscator now returns an empty string instead of obfuscated code if source code is empty

v0.7.0-dev.2

• Fix of incorrect Utils.decToHex method

v0.7.0-dev.1

• Breaking API change: now obfuscate(sourceCode, options) returns ObfuscationResult object instead string. ObfuscationResult object contains two public methods: getObfuscatedCode() and getSourceMap().
• CLI. Now any code can be obfuscated through CLI javascript-obfuscator command. See README.md for available options.
• New option sourceMap enables source map generation for obfuscated code.
• New option sourceMapMode specifies source map generation mode.
