Today, we’re releasing TypeScript 0.9.1.1, a hotfix release of TypeScript 0.9.1. The 0.9.1.1 release addresses 25 issues discovered by the community and includes fixes for compiler crashes, memory consumption, type system correctness, and more.
This release also temporarily adds back in the flags to allow “import x = module(…)” and the ‘bool’ type (–allowimportmodule and –allowbool, respectively), to help large codebases that have yet to upgrade. This is the last release to support these deprecated syntax forms, so please update your codebases to get them ready for 1.0.
Note to users of previous versions of TypeScript – there is a list of breaking changes with older versions listed here.
