The release should be fairly non-disruptive for the users, bringing some minor bug-fixes and modest portion of enhancements. Nevertheless, distribution maintainers may be somewhat disturbed. Time-proven buildsystem is ditched, documentation location has changed. Please consult bundled packaging templates for RPM, deb and snap for new build description and file locations.

Release highlights


  • autotools-based buildsystem
  • server functionality
  • Java applet (Java engine and Java console application remain intact)
  • documentation in an in-house, proprietary format


  • printing expressions in R-compatible form
  • improved printing of arrays and associations
  • access to keys and head of associations
  • improved unicode support


  • hand-crafted templates for building deb, rpm and snap packages are provided
  • tests are shipped with binary packages

Altogether, over 30 issues were closed in this release.

This is a hotfix release, fixing an issue with automake-based build system.

The fix is only relevant if you are going to build yacas from sources using automake. Otherwise everything in this release is identical to version 1.4.0. Hence, no binary packages are provided for this release.

Please note that the automake-based build system is considered obsolete and the cmake-based build system should be used instead.

This is the first release of yacas after moving over to GitHub, license change and switching to the new webpage and new documentation system. Despite all the changes, yacas keeps up as a small, flexible, portable, backward-compatible, easy to use and extend Computer Algebra System that just makes the computer calculations easy.
