mruby 1.3.0

written by Daniel Bovensiepen on 2017-07-09 14:45:28 UTC

Since 16. November 2015 mruby 1.3 was in the making. After 596 days and 907 commits by 38 contributors I can happily announce that we released the latest stable version of mruby on 4. July 2017. mruby is a lightweight implementation of the Ruby programming language. Applications of mruby include embedded programming on micro-controllers, sandboxed Ruby scripting support, standalone binaries (e.g. command-line tools and deployment receipts), container management and more.

Language

The following language specific changes were done:

API

The API has changed in the following ways:

Documentation

Features are only useful if users know that they exist and how to use them. For this reason we worked on improving the general documentation situation of mruby, including a description of how mruby is different to standard Ruby:

Build System

One of the targets of mruby is to be used on as many platforms as possible. The following improvements of the build system of mruby should help to make mruby easier to be used in different environments:

Security audit and general bug fixing

The majority of the work on this release was to fix bugs. As mentioned earlier, the Shopify bug bounty served as a security audit of the mruby code base. It revealed a massive amount of potential security related issues inside the source. All together 293 commits were contributed to fix security related issues related to this bug bounty. Another 159 commits were provided to fix general bugs.
