Release Notes

terser/terser

v5.7.0

Compare Source

• Several compile-time evaluation and inlining fixes
• Allow reduce_funcs to be disabled again.
• Add spidermonkey options to parse and format (#​974)
• Accept {get = "default val"} and {set = "default val"} in destructuring arguments.
• Change package.json export map to help require.resolve (#​971)
• Improve docs
• Fix export default of an anonymous class with extends

v5.6.1

Compare Source

• Mark assignments to the .prototype of a class as pure
• Parenthesize await on the left of ** (while accepting legacy non-parenthesised input)
• Avoided outputting NUL bytes in optimized RegExps, to stop the output from breaking other tools
• Added exports to domprops (#​939)
• Fixed a crash when spreading ...this
• Fixed the computed size of arrow functions, which improves their inlining

v5.6.0

Compare Source

• Added top-level await
• Beautify option has been removed in #​895
• Private properties, getters and setters have been added in #​913 and some more commits
• Docs improvements: #​896, #​903, #​916

v5.5.1

Compare Source

• Fixed object properties with unicode surrogates on safari.

v5.5.0

Compare Source

• Fixed crash when inlining uninitialized variable into template string.
• The sourcemap for dist was removed for being too large.

v5.4.0

Compare Source

• Logical assignment
• Change let x = undefined to just let x
• Removed some optimizations for template strings, placing them behind unsafe options. Reason: adding strings is not equivalent to template strings, due to valueOf differences.
• The AST_Token class was slimmed down in order to use less memory.

v5.3.8

Compare Source

• Restore node 13 support

v5.3.7

Compare Source

Hotfix release, fixes package.json "engines" syntax

v5.3.6

Compare Source

• Fixed parentheses when outputting ?? mixed with || and &&
• Improved hygiene of the symbol generator

v5.3.5

Compare Source

• Avoid moving named functions into default exports.
• Enabled transform() for chain expressions. This allows AST transformers to reach inside chain expressions.

v5.3.4

Compare Source

• Fixed a crash when hoisting (with hoist_vars) a destructuring variable declaration

v5.3.3

Compare Source

• source-map library has been updated, bringing memory usage and CPU time improvements when reading input source maps (the SourceMapConsumer is now WASM based).
• The wrap_func_args option now also wraps arrow functions, as opposed to only function expressions.

v5.3.2

Compare Source

• Prevented spread operations from being expanded when the expanded array/object contains getters, setters, or array holes.
• Fixed very slow self-recursion in some cases of removing extraneous parentheses from + operations.

v5.3.1

Compare Source

• An issue with destructuring declarations when pure_getters is enabled has been fixed
• Fixed a crash when chain expressions need to be shallowly compared
• Made inlining functions more conservative to make sure a function that contains a reference to itself isn't moved into a place that can create multiple instances of itself.

v5.3.0

Compare Source

• Fixed a crash when compressing object spreads in some cases
• Fixed compiletime evaluation of optional chains (caused typeof a?.b to always return "object")
• domprops has been updated to contain every single possible prop
