- Update to version 5.4:
* Preserved Narrowing in Closures Following Last Assignments
* The NoInfer Utility Type
* Object.groupBy and Map.groupBy
* Support for require() calls in --moduleResolution bundler and --module preserve
* Checked Import Attributes and Assertions
* Quick Fix for Adding Missing Parameters
* Auto-Import Support for Subpath Imports
* Upcoming 5.5 Deprecations:
+ TypeScript 5.0 deprecated the following options and behaviors:
charset
target: ES3
importsNotUsedAsValues
noImplicitUseStrict
noStrictGenericChecks
keyofStringsOnly
suppressExcessPropertyErrors
suppressImplicitAnyIndexErrors
out
preserveValueImports
prepend in project references
implicitly OS-specific newLine
To continue using them, developers using TypeScript 5.0 and other more recent versions
have had to specify a new option called ignoreDeprecations with the value "5.0".
However, TypScript 5.4 will be the last version in which these will continue to function as normal.
By TypeScript 5.5 (likely June 2024), these will become hard errors,
and code using them will need to be migrated away.
