1.6. Release notes for version 7.0.2

The significant changes to the various parts of the compiler since 7.0.1 are listed in the following sections.

1.6.1. Compiler

  • The old [$foo| ... |] syntax works again, but is deprecated.

  • There have been significant improvments to the new type checker.

1.6.2. GHCi

  • Loading .a libraries is now possible on all platforms. A .o library will still be used by preference if both exist. GHCi will no longer warn about missing .o libraries.

  • We now close .ghci files after reading them, which on Windows machines allows them to be altered while GHCi is running.

  • It is now possible to :unset the ghci variables (args, prog, prompt, editor and stop).

1.6.3. Runtime system

  • DTrace is now supported on Solaris, in addition to OS X.

1.6.4. Build system

  • OS X builds on 10.6 now work on both 10.5 and 10.6.

  • Windows installations now include the libstdc++ DLL.
