This document is a record of the changes made to A-Shell 6.3/6.4, beginning with build 1500 of Autumn 2015. In March 2017, at build 1546.1.2, three things happened:
• The version was renamed from 6.3 to 6.4.
• Active development ceased. From that point forward, only bug fixes and minor enhancements were added to A-Shell. All new development took place in the then-current developers' version, 6.5.
• A new section of this document, "Version Highlights," was created from the existing materials. This became the core of the 6.4 Release Notes.
Changes to the previous versions of A-Shell can be found with their respective software releases on the A-Shell downloads page.
Organization
In addition to the material presented in the Version Highlights section, this document contains two inter-dependent sets of notes:
• Notes by Subject: A record of all new features and improvements that might be of interest to developers. This section does not include bug fixes.
• Notes by Version and Date: A record all A-Shell changes regardless of type or significance, including bug fixes and minor refinements.
Navigation
Any time a topic in the table of contents (at left) displays a little book or folder next to it, click on the topic or mark to expand the table of contents and see the individual notes.
Text Colors
In the "Notes by version and date" section, the authors use text colors to keep track of the status of the different development notes:
• Items that have been transferred to the main A-Shell documentation set (blue). color = 0,0,204
• Bug fixes, which are not transferred (teal). color = 0,128,128
• Minor enhancements and changes that do not need to be transferred (violet). color = 153,0,204
