VCC v2.1.8.1 Tandy Color Computer 3 Emulator

VCC v2.1.8.1 August/2023
◦ Minor bug fixes.
◦ New versioning system

VCC version numbering in the past has been some what haphazard. In attempt to remedy this we have decided to codify the VCC version numbering scheme as follows: The VCC version number consists of "VCC-" followed by 4 numbers separated by dots, for example: "Vcc-2.1.8.1". The first number represents the "fork." Fork one is considered to be the original code from Joseph Forgeone. The current fork is "2". It promises to function on Windows XP and Windows 7 operating systems. We might want to add capabilities that will not work on these older systems. If we do that we will create a third "fork." This will allow us to backport changes from fork 3 code back to fork 2. The second number represents a major version. It will be used if very significant changes are made in the way VCC functions (not likely happen anytime soon). The third number represents normal releases, typically done one or two times per year. The fourth number represents bug fixes to the release. These are changes to VCC that correct errors and bugs in the intended functionality of the release. Binaries containing these changes will be updated in the affected release files.
