mingw-get version 0.1-alpha-5.1 has been released. This version of the mingw-get command-line installer and installation management program fixes issues related to dependency resolution when upgrading packages.
mingw-get-inst version 20110211 has been released. It includes the latest version of mingw-get (0.1-alpha-5.1) and a more recent snapshot of the package manifest data (2011 Feb 11). mingw-get-inst is a graphical installer that can be used for INITIAL installation of MinGW compilers and MSYS tools (upgrading an existing installation should be done using the command line mingw-get tool). In fact, mingw-get-inst is merely a simple GUI wrapper around the command line tool.
MinGW GCC 4.5.2 has been released. It can be newly installed using either mingw-get or mingw-get-inst. Existing installations may be upgraded using the following command: 'mingw-get upgrade gcc g++ fortran ada objc' (omit languages as desired; however, all currently installed languages must be upgraded simultaneously).
