Smalltalk inspired Pharo project releases version 1.4
The developers of the Pharo project have released version 1.4 of their implementation of the open source Smalltalk-inspired language and environment. Pharo is a fork of another open source Smalltalk implementation, which set out to remove non-essential code from Squeak and act as a reference platform for the Smalltalk web application platform, Seaside.
The new release includes over 860 "treated" issues, with a new code model, Ring, designed to give the classes of Pharo better meta-support, allowing tools to interact with them directly and to support historical analysis; a presentation from 2010 explains the motivation for the Ring development.
Other changes in Pharo 1.4 include better headless support and improvements to servers and tools such as the Inspector and Debugger. The user interface library now has its own theme, supports window grouping with tabs and handles drag and drop for lists with multiple selections. More changes are detailed in the release announcement.
Pharo 1.4 is available to download for Linux, Mac OS X and Windows and is published under an MIT licence.
