Earlier this year, the Pharo development team announced the availability of Pharo 13 ( https://pharo.org/news/2025-05-21-pharo13-released.html ). For our September 2025 meeting, Pharo's release manager Esteban Lorenzano will give us a tour of the new version - what's changed, and what remains the same. Esteban Lorenzano ( https://github.com/estebanlm ) studied Computer Sciences at Universidad de Buenos Aires, and worked since 1994 in several object-oriented and low-level technologies, in different software companies, serving in various positions from programmer to senior architect. In 2007 he co-founded Smallworks to offer Pharo-based agile development projects. Since 2012 he dedicated full time to developing the Pharo code and community. He works with the INRIA-EVREF team in Lille, France, as core developer for Pharo, being responsible with the coordination of new releases and the implementation and maintenance of several Pharo libraries. This will be an online meeting. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/ukstug/events/310635970/) to receive the meeting details.
