What's new in Mercury 0.13.1:

February 7th, 2009

This release is primarily a bug-fix release. The problems fixed include:
· polymorphic insts and mode-specific clauses did not work together.
· polymorphic insts and export pragmas did not work together.
· the compiler was not correctly enforcing the restriction that type variables in instance declarations should be distinct.
· the compiler sometimes performed superclass reduction incorrectly, causing it to reject valid typeclass constraints.
· installation of static archives on Mac OS X using mmc --make now works correctly. Previously, static archives caused linking problems because the table of contents was not being updated after installation.
· non-exported typeclasses sometimes resulted in incomplete interface files being generated.

· In addition to the above bug-fixes we have the following addition to the standard library.
· We have added a new module `rtree', that provides region trees. These are a standard data structure for querying spatial information.
