When atlassian release the minor or major version of any application?
what is the reason to release the major or minor version?

and what is the difference between release and version related to atlassian tools?

Hi Gajanan,

there are some reasons for upgrades, often the first mentioned are bug fixes, security fixes and the introduction of new features - along with performance improvements and maintaining the access to support.

Please refer to the document "Atlassian Server Bug Fix Policy" for a better understanding of the terminology used for releases as:

• Platform release (4.0) contains significant or breaking changes. For example changes or removal of existing APIs, significant changes to the user experience, or removal or a major feature.
• Feature release (4.6) can contain new features, changes to existing features, changes to supported platforms (such as databases, operating systems, Git versions), or removal of features. These were previously referred to as 'major' releases by most products.
• Bug fix release (4.6.2) can contain bug fixes, stability and performance improvements. Depending on the nature of the bug fixes they may introduce minor changes to existing features, but do not include new features or high risk changes, so can be adopted quickly. We recommend regularly upgrading to the latest bug fix release for your current version. These were previously referred to as 'maintenance' releases by most products.
