Ephemerons in P11
by Guillermo Polito March 20, 2023

March 20, 2023

Hi all, For those that may not be following the day-to-day development, you may be interested in that Ephemeron support is now enabled in Pharo 11 for one week or so (VM version 10.0.0, Image build 627). Here are some takeaways and actions to take you may be interested in: To get the latest version: - ZeroConf works out of the box - You must update your VMs in the pharo launcher About compatibility: - old images will run on both the old and latest VMs - new images will only run on the latest VM You can read more on: https://github.com/pharo-project/pheps/blob/main/phep-0003.md Cheers, Guille

Pharo Issue tracker / github "projects" access
by Marcus Denker March 16, 2023

March 16, 2023

Hi, When we started with using github, real issue tracker use (e.g adding tags, closing issues if you are not the ownerâ¦) was only possible with write access to the repository. This new changed (I guess since a while) and we can now invite people to give you more access to make it easy to help. If you are interested â> send a mail to me. This of course makes sense mostly for people who already contributed some PRs. (I will document this on the pharo.org <http://pharo.org/> website and the github reposiitory so this will be east to discover) Marcus
