Quorum Patches

This is a list of patches pushed to live. For small patches pushed by the team, we sometimes write notes for the last several. This should be considered an abridged list of changes.

Quorum 4.0.6 January 21st, 2017

This patch includes a variety of small changes as we continue with Quorum 4. Besides the fixes below, this version includes a new version of the website, which should bring us one step closer to web support for many of Quorum's features.

Quorum 4.0.5 September 9th, 2016

This patch includes a variety of small changes as we continue with Quorum 4:

Quorum 4.0.4 August 6th, 2016

This patch fixes a variety of issues found at EPIQ 2016 and after by users. This patch includes:

We would like to thank Sina Bahram, Pranav Lal, and DJ Prater for their help in identifying some of the problems in the above list.

Quorum 4.0 July 5th, 2016

Quorum 4.0 is the next major update to the programming language. In it, we have provided a variety of new features and improvements for many systems. The highlights of this release include support for 3D gaming (audio + visual), mobile support (iOS only), and significant improvements across the board to the development environment (e.g., navigation, folding). Besides these larger changes, we have spent considerable time making improvements to a large number of systems in Quorum and have expanded on many. This includes the addition of linear algebra libraries, improvements to the existing LEGO libraries, and significant improvements to the design of the game engine. Finally, we have added many new tutorials on a variety of systems.

3D Gaming

One of the major features in Quorum 4.0 is a new 3D gaming system. On the backend, Quorum uses OpenGL, one of several standard gaming engines for commercial games. On the user level, however, we have spent significant effort working with people writing games in Quorum to try and iterate on our design. Overall, the 2D system has been improved and simplified in a variety of ways, the overall libraries have been unified, and accessibility support is now baked in in ways we think are easier to understand.

Besides this, 3D support itself has been modeled similarly to 2D. In other words, with 2D, you could load an image or sound and move it around. With 3D, while traditional modeling applications in OpenGL or Direct3D require quite a bit of knowledge about computer graphics, our libraries try to simplify those aspects of the system that we can. The idea is, besides the added dimension, to make the 2D and 3D systems feel as similar as possible to the programmer to aid in learning. Here are some additional highlights for the new engine:

Visual Games

The visual aspect of Quorum has now been significantly improved. We now support 3D games, built on our linear algebra library. We have also conducted significant user testing on creating games with our libraries and have spent considerable time re-tooling them in order to make them easier to use. This was conducted for both the 2D game system and the newer 3D one. To make things easier, we have also unified the libraries for 2D and 3D games, so that the way you interact with them is as similar as possible. Below are some highlights from the visual part of the system.

Auditory Games

In addition to broad gaming features, we have expanded on the auditory system in Quorum. Here are the features we now support.

Development Environment Improvements

This update adds a variety of development environment features. This includes brace matchers, highlighters, a rewrite of the navigator, efficiency improvements, and a variety of other features.

General Improvements and Bug Fixes

This section includes a variety of improvements or bug fixes the team worked on for this release.

Documentation Improvements

We have made a number of changes to the online documentation in Quorum, including adding a variety of lessons and tutorials. These include:

This update is deployed to NetBeans only, but not as a separate zip file on the release servers.

Quorum 3.0 June 30th, 2015

Quorum 3.0 represents the most significant change to the Quorum programming language since its inception and is a near-complete rewrite. When the Quorum project first began, it was written in Java, was interpreted, and we were really just trying to make programming a little easier. As of 3.0, the project has gone further than we ever imagined: Quorum is now faster, robust, and written in itself. As is a long tradition in programming language design, once a language is sufficiently powerful to write the next version in itself, so-called self-hosting, it is a sign that the language is becoming increasingly mature. On Quorum, we have finally reached this milestone and will now be shifting our attention to improved library and development environment support. Library requests to the team, or contributions, are welcome.

We had a number of technical goals in mind for the Quorum 3.0 release. We highlight some of the most significant alterations below:

Standard library changes

Integrated Development Support changes

Major language changes

Type system/variable changes

Exceptions (Error) system changes

Control Structure changes

Compiler Support

Other changes

Quorum 2.1 December 16th, 2013

Standard Library and compiler Fixes/Changes

Quorum 2.0.1 August 13th, 2013

This is a bug fix release for the Quorum 2.0 branch.

Quorum 2.0 June 6th, 2013

Quorum 2.0 includes a host of improvements to the type system, adds the ability to call actions on primitives, includes minor syntactic improvements, and enhances the code completion helper libraries.

Quorum 1.7 February 25th, 2013

Quorum 1.7 adds in a new type inference system, upgrades the internal architecture substantially, and fixes a number of known bugs.

Quorum 1.6 September 9th, 2012

Quorum 1.6 contains a number of important bug fixes.

Quorum 1.5 June 26th, 2012

We previously had the following:

if a = b then
end else if c = d then

end else then
end

The syntax is now the following:

if a = b
elseif c = d

else
end

We may change the design of this construct again in the future if we find more, or better, evidence for against any particular design. Users, or other researchers, that have conducted formal empirical studies, with corresponding evidence, that they think might illuminate more decisions here should let us know.

Quorum 1.0 January 30th, 2012

This is the initial release of the Quorum programming language. Currently, Quorum has the following features:
