terser - npm Package Versions

v4.3.8

• Typescript typings fix

v4.3.7

• Parsing of regex options in the CLI (which broke in v4.3.5) was fixed.
• typescript definition updates

v4.3.6

(crash hotfix)

v4.3.5

• Fixed an issue with DOS line endings strings separated by \ and a new line.
• Improved fix for the output size regression related to unused references within the extends section of a class.
• Variable names of anonymous functions (eg: const x = () => { ... } or var func = function () {...}) are now preserved when keep_fnames is true.
• Fixed performance degradation introduced for large payloads in v4.2.0

v4.3.4

• Fixed a regression where the output size was increased when unused classes were referred to in the extends clause of a class.
• Small typescript typings fixes.
• Comments with @preserve, @license, @cc_on as well as comments starting with /*! and /**! are now preserved by default.

v4.3.3

• Fixed a problem where parsing template strings would mix up octal notation and a slash followed by a zero representing a null character.
• Started accepting the name async in destructuring arguments with default value.
• Now Terser takes into account side effects inside class extends clauses.
• Added parens whenever there's a comment between a return statement and the returned value, to prevent issues with ASI.
• Stopped using raw RegExp objects, since the spec is going to continue to evolve. This ensures Terser is able to process new, unknown RegExp flags and features. This is a breaking change in the AST node AST_RegExp.

v4.3.2

• Typescript typing fix
• Ensure that functions can't be inlined, by reduce_vars, into places where they're accessing variables with the same name, but from somewhere else.

v4.3.1

• Fixed an issue from 4.3.0 where any block scope within a for loop erroneously had its parent set to the function scopee
• Fixed an issue where compressing IIFEs with argument expansions would result in some parameters becoming undefined
• addEventListener options argument's properties are now part of the DOM properties list.

v4.3.0

• Do not drop computed object keys with side effects
• Functions passed to other functions in calls are now wrapped in parentheses by default, which speeds up loading most modules
• Objects with computed properties are now less likely to be hoisted
• Speed and memory efficiency optimizations
• Fixed scoping issues with try and switch

v4.2.1

• Minor refactors
• Fixed a bug similar to #369 in collapse_vars
• Functions can no longer be inlined into a place where they're going to be compared with themselves.
• reduce_funcs option is now legacy, as using reduce_vars without reduce_funcs caused some weird corner cases. As a result, it is now implied in reduce_vars and can't be turned off without turning off reduce_vars.
• Bug which would cause a random stack overflow has now been fixed.
