IEEE Software is publishing a special issue on Release Engineering, to appear in the March/April 2015 issue (Vol. 32, No. 2). Martin Michlmayr, Brian Fitzgerald and I have written an article on Why and How Open Source Projects should adopt time-based releases, which will be included in the special issue. The article outlines the numerous benefits of time-based releases (as opposed to feature-based releases) and provides some basic guidelines on how to achieve this.
Our paper “Microblogging in Open Source Software Development: The Case of Drupal Using Twitter” was accepted for publication in IEEE Software. This work is led by Dr Xiaofeng Wang from the Free University of Bolzano, in collaboration with Ilona Kuzmickaja, Pekka Abrahamsson and Brian Fitzgerald. You can find the pre-print here. While there have been numerous academic papers on Twitter, few have been published targeting the Software Engineering community, and so far most of them have been conference papers.
