Scheduled Maintenance Releases

In order to make our maintenance release schedule more predictable for customers, and in an attempt to ensure that bug fixes are passed on to users in a timely fashion, we will now be implementing a regime of pre-scheduled maintenance releases.

A maintenance release is classified as one that contains day-to-day bug fixes that do not include serious data loss issues or security flaws. They are designated (usually) by an incrementing of the third version digit, such as 3.7.1, 3.7.2, 3.7.3 etc.

From now on, the longest time customers will ever wait for bug fixes to be released will be two months.

Toward the end of each month, the developers will evaluate the quantity and severity of the bugs found and fixed in the previous month. If there has been an abnormally high number of bugs reported, or the severity of some of the bugs fixed is considered to warrant an early release, the next maintenance version will be brought forward and will be released to customers on the final Tuesday of that month.

If the quantity and severity of bugs is not unusual, the maintenance version will be released on the final Tuesday of the month, two months following the previous maintenance version.

Security Flaws and Data-Loss Bugs

As usual, we will fix any security flaws and serious data loss bugs as soon as we become aware of their existence, and will do a release as soon as the fix is implemented and tested.

Wherever possible, this will be done in the form of a Patch Level (PL) release, where only a small number of files are updated and no upgrade script is required, but when this is not possible, a full release will be performed, as was the case with 3.6.10 and 3.7.0 Release Candidate 4.
