Dear Pharo users and dynamic language lovers:
We have released Pharo https://pharo.org/ version 13!
What is Pharo?
Pharo is a pure object-oriented programming language and a powerful
environment focused on simplicity and immediate feedback.

Simple & powerful language: No constructors, no types declaration,
no interfaces, no primitive types. Yet a powerful and elegant
language with a full syntax fitting in one postcard! Pharo is
objects and messages all the way down.
Live, immersive environment: Immediate feedback at any moment of
your development: Developing, testing, debugging. Even in production
environments, you will never be stuck in compiling and deploying
steps again!
Amazing debugging experience: Pharo environment includes a debugger
unlike anything you’ve seen before. It allows you to step through
code, restart the execution of methods, create methods on the fly,
and much more!
Pharo is yours: Pharo is made by an incredible community, with more
than 100 contributors for the last revision of the platform and
hundreds of people constantly contributing with frameworks and
libraries.
Fully open-source: Pharo full stack is released under MIT
<https://opensource.org/licenses/MIT> License and available on
GitHub <https://github.com/pharo-project/pharo>
… more on the Pharo Features page <http://www.pharo.org/features>.
In this iteration of Pharo, we continue working on our objectives of
improvement, clean-up and modularization.
Also, we included a number of usability and speed improvements.
A detailed list of changes and improvements is available in our
Changelog
https://github.com/pharo-project/pharo-changelogs/tree/master/weekly
(weekly based)
Some highlights of this amazing version:
Highlights
Tools
Spec Tools remembering their size
Microdown enhancements
HDPI support
Zoomable UI
New list, tables and trees, allowing any presenter as their content
Better source code text navigation and edition
New Process Browser
New Transcript (introducing also the Object Transcript)
Organic window manager
System
Better refactorings UX Cleaner leaner code logic
More robust and faster halt implementation
Debug points to enhance the debugging experience
Clean-ups
Virtual machine
Async IO using epoll on unixes
Faster byte array / string comparisons
Improve Windows support for non ASCII filenames
FreeBSD support
Update SDL2 version in OSX (Intel & Apple)
Minimal MacOS version required raised to MacOS 11 and above
Development Effort
This new version is the result of 698 Pull Requests integrated just in
the Pharo repository.
We have closed 865 issues and received contributions from more than 70
different contributors.
We also have a lot of work in the separate projects that are included in
each Pharo release:
http://github.com/pharo-project/pharo-vm
Contributors
We always say Pharo is yours. It is yours because we made it for you,
but most importantly, because it is made by the invaluable contributions
of our great community (yourself).
A large community of people from all around the world contributed to
Pharo 13.0 by making pull requests, reporting bugs, participating in
discussion threads, providing feedback, and a lot of helpful tasks in
all our community channels.
Thank you all for your contributions.

Congratulations. Keep up the good work.
Are we going to have a tag in the Github repo for this release marking the
commit that produced this version? Because it looks strange that the latest
release appears as v12.0.0
Regards
Gabriel
