Date: December 16, 2010
MD5SUM: 4765267e398b4f50e6394a11195ceccd
Changes: Most functionality of the GfxDriver class has been moved to the Mesh, Texture, VertexBuffer, and ShaderProgram classes in order to simplify and increase the modularity of the code. OpenGL ES 1.1 support has been added. Support for loading PNG images and TrueType fonts on iOS has been added. Xcode projects for Mac OS X and iOS have been added.

DromeEngine-0.4.2.tar.gz (source tarball)

Date: October 3, 2010
MD5SUM: b8f838110b67c2c244e8322a98244db7
Changes: More inline documentation has been added to header files. The SDL and Cocoa implementations of the IOContext class have been modified to allow attributes such as window dimensions and window title to be changed after an IOContext has been initialized.

DromeEngine-0.4.1.tar.gz (source tarball)

Date: September 12, 2010
MD5SUM: 24c53cc667814e5964abd2f954c713db

MD5SUM: f11eee3f00dec397ecfeeda1b8c9c4e4
Changes: This is the first new version of Drome Engine in several years. Although the name is the same, it has been completely rewritten and is essentially a new engine. It does not have all of the features of the previous version, but the code is much cleaner, simpler, and more modular than before, which will make it much more useful overall.
