IWST is the International Workshop on Smalltalk Technologies. The goal of the workshop is to create a forum around contributions and experiences in building or using technologies related to Smalltalk. While the maturity of presented ideas and results is not crucial, their presentation is expected to trigger discussion and exchange of ideas. The topics of your paper can be on all aspects of Smalltalk, theoretical as well as practical. Authors are invited to submit research articles or industrial papers. This year we will again have two different tracks: Two-Round Paper Submission. As in the previous year, submission will be in two rounds: Extended abstracts are submitted to present at the conference Later, full/short papers are submitted for proceedings publications Presenting Previously Published Works. We also invite authors of contributions related to IWST's topics, accepted for publication in Journals and Proceedings of top-rated international conferences within the previous 2 years, to submit an abstract and present their published results to the IWST workshop collocated with ESUG. Authors will be invited to present their paper after checking that the submission meets the above criteria. Having the submissions already reviewed and accepted by the peers, they will not be reviewed again for technical content.
