Releases Version Numbering
Starting with the version 6.x.x releases, the version numbering has changed.
Before delving into the release numbering, the first thing you should know is that ClearOS starts with source code from a prominent North American Linux vendor. Their release numbering looks like:
6.0 - released November 2010
6.1 - released May 2011
6.2 - released December 2011
6.x - etc., approximately every 6 months
Every three-ish years, the upstream vendor also releases a major update. So in 2013/2014, you can expect to see version 7.0.
What is a bit misleading about this version numbering is that the releases are actually rolling. In other words, if you want to keep up with all the security updates, you need to keep “upgrading” to the latest 6.x releases. The interim dot-releases are deprecated every 6 months and the operating system will automatically upgrade to the latest.
Now that you have an understanding of the version numbering from the upstream vendor, let's take a look at ClearOS. At a technical level, we will use a 3-digit release number:
To give you a real world example, when the upstream vendor released version 6.2 in December 2011, we followed suit with releasing ClearOS Enterprise 6.2.0 later in the month.
Like any good administrator, you want to keep up with the latest security fixes. For that reason, a system that was installed with the 6.2.0 release will - under the hood - be upgraded to 6.3.x, 6.4.x, 6.5.x, etc.
At a high level, the version will simply be referred to as “6”. There's no need to complicate matters in casual conversation, writing blogs, etc. Given the rolling nature of the underlying security updates, it's better to say something like:
Hey David, have you tried the Content Filter in ClearOS 6?
