(in reversed chronological order)

==============================================================================
6
Version 0.9 (in Erlang/OTP R14B02)
7
----------------------------------
8
- Major rewrite; all code has been cleaned up and placed in one file.
9
The only reason why this is not version 1.0 yet is that there is no proper
10
documentation for typer which can be displayed in the www.erlang.org site.
11
- Added ability to receive the set of exported types and report unknown ones.
12
- Better handling of overloaded contracts; especially erroneous ones on which
13
typer does not crash anymore.
14
- Fixed problem that caused typer to hang when given a file whose module name
15
did not correspond to the file name.
16
- Added two undocumented options that may come very handy when trying to
17
understand why typer reports some particular set of types for the functions
18
in a module. These options are mainly for typer developers at this point,
19
but may become documented in some future version.
