by Koen De Hondt Sept. 26, 2023

Sept. 26, 2023

Dear Pharo users and developers, Last week at ESUGâ23 I presented the results of the survey on the usage of the Pharo Browser. Half an hour was not enough to show and discuss all questions and answers. You find all results on my blog: https://all-objects-all-the-time.st/#/blog/posts/3. If you have questions, comments, or suggestions, please do not hesitate to send me a message. Best regards, Koen

ANN: New voyage and mongotalk versions, for mongodb >=5
by Esteban Lorenzano Sept. 14, 2023

Sept. 14, 2023

Hi, We just made a new release of the mongotalk drivers [1], which replaces the drivers for mongodb, making possible for Pharo users to connect with a recent mongo database (versions 5 and beyond). Old legacy driver is still accessible with some minimal work, in case of need [2]. We also updated Voyage to use the new driver by default [3]. Enjoy, Esteban [1] https://github.com/pharo-nosql/mongotalk/releases/tag/v2.0 [2] https://github.com/pharo-nosql/mongotalk#older-mongo-versions--5 [3] https://github.com/pharo-nosql/voyage/releases/tag/v2.0
