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
