GNU poke 3.0 released

Item posted by Jose E. Marchesi <jemarch> on Wed 25 Jan 2023 07:08:23 PM UTC.

I am happy to announce a new major release of GNU poke, version 3.0.

This release is the result of a year of development.  A lot of things have changed and improved with respect to the 2.x series; we have fixed many bugs and added quite a lot of new exciting and useful features.  See below for a description of many of them.

From now on, we intend to do not one but two major releases of poke every year.  What is moving us to change this is the realization that users have to wait for too long to enjoy new features, which are continuously being added in a project this young and active.

The tarball poke-3.0.tar.gz is now available at
https://ftp.gnu.org/gnu/poke/poke-3.0.tar.gz.

> GNU poke (http://www.jemarch.net/poke) is an interactive, extensible editor for binary data.  Not limited to editing basic entities such as bits and bytes, it provides a full-fledged procedural, interactive programming language designed to describe data structures and to operate on them.


Thanks to the people who contributed with code and/or documentation to this release.  In certain but no significant order they are:


   Mohammad-Reza Nabipoor
   Arsen Arsenović
   Luca Saiu
   Bruno Haible
   apache2
   Indu Bhagat
   Agathe Porte
   Alfred M. Szmidt
   Daiki Ueno
   Darshit Shah
   Jan Seeger
   Sergio Durigan Junior

   ... and yours truly


As always, thank you all!

But wait, this time we also have special thanks:

To Bruno Haible for his invaluable advise and his help in throughfully testing this new release in many different platforms and configurations.

To the Sourceware overseers, Mark Wielaard, Arsen Arsenović, and Sam James for their help in setting up the buildbots we are using for CI at sourceware.
