6.0 Current (development branch)
5.3 Release
The latest -CURRENT version is always referred to as -CURRENT, while the latest -STABLE release is always referred to as -STABLE. In this figure, -STABLE refers to 4-STABLE while -CURRENT refers to 5.0-CURRENT following 5.0-RELEASE. <citation><xref linkend="freebsd-releng"/></citation>
A <quote>major release</quote> is always made from the -CURRENT branch. However, the -CURRENT branch does not need to fork at that point in time, but can focus on stabilising. An example of this is that following 3.0-RELEASE, 3.1-RELEASE was also a continuation of the -CURRENT-branch, and -CURRENT did not become a true development branch until this version was released and the 3-STABLE branch was forked. When -CURRENT returns to becoming a development branch, it can only be followed by a major release. 5-STABLE is predicted to be forked off 5.0-CURRENT at around 5.3-RELEASE. It is not until 5-STABLE is forked that the development branch will be branded 6.0-CURRENT.
A <quote>minor release</quote> is made from the -CURRENT branch following a major release, or from the -STABLE branch.
The first release this actually happened for was 4.5-RELEASE, but security branches were at the same time created for 4.3-RELEASE and 4.4-RELEASE.
There is a terminology overlap with respect to the word "stable", which leads to some confusion. The -STABLE branch is still a development branch, whose goal is to be useful for most people. If it is never acceptable for a system to get changes that are not announced at the time it is deployed, that system should run a security branch.
Following and including, 4.3-RELEASE<_:footnote-1/>, when a minor release has been made, it becomes a <quote>security branch</quote>. This is meant for organisations that do not want to follow the -STABLE branch and the potential new/changed features it offers, but instead require an absolutely stable environment, only updating to implement security updates. <_:footnote-2/>
Each update to a security branch is called a <quote>patchlevel</quote>. For every security enhancement that is done, the patchlevel number is increased, making it easy for people tracking the branch to see what security enhancements they have implemented. In cases where there have been especially serious security flaws, an entire new release can be made from a security branch. An example of this is 4.6.2-RELEASE.
Model summary
To summarise, the development model of FreeBSD can be seen as the following tree:
The overall development model
_ external ref='freebsd-code-model' md5='__failed__'
<imageobject><imagedata fileref="freebsd-code-model"/></imageobject> <textobject><_:literallayout-1/></textobject> <textobject> <phrase>Refer to paragraphs below for a screen-reader friendly version.</phrase> </textobject>
The tree of the FreeBSD development with ongoing development efforts and continuous integration.
The tree symbolises the release versions with major versions spawning new main branches and minor versions being versions of the main branch. The top branch is the -CURRENT branch where all new development is integrated, and the -STABLE branch is the branch directly below it. Below the -STABLE branch are old, unsupported versions.
Clouds of development efforts hang over the project where developers use the development models they see fit. The product of their work is then integrated into -CURRENT where it undergoes parallel debugging and is finally merged from -CURRENT into -STABLE. Security fixes are merged from -STABLE to the security branches.
Hats
Many committers have a special area of responsibility. These roles are called hats. These hats can be either project roles, such as public relations officer, or maintainer for a certain area of the code. Because this is a project where people give voluntarily of their spare time, people with assigned hats are not always available. They must therefore appoint a deputy that can perform the hat's role in their absence. The other option is to have the role held by a group.
Many of these hats are not formalised. Formalised hats have a charter stating the exact purpose of the hat along with its privileges and responsibilities. The writing of such charters is a new part of the project, and has thus yet to be completed for all hats. These hat descriptions are not such a formalisation, rather a summary of the role with links to the charter where available and contact addresses.
General Hats
Contributor
A Contributor contributes to the FreeBSD project either as a developer, as an author, by sending problem reports, or in other ways contributing to the progress of the project. A contributor has no special privileges in the FreeBSD project. <citation><xref linkend="freebsd-contributors"/></citation>
Committer
A person who has the required privileges to add their code or documentation to the repository. A committer has made a commit within the past 12 months. <citation><xref linkend="freebsd-bylaws"/></citation> An active committer is a committer who has made an average of one commit per month during that time.
It is worth noting that there are no technical barriers to prevent someone, once having gained commit privileges to the main- or a sub-project, to make commits in parts of that project's source the committer did not specifically get permission to modify. However, when wanting to make modifications to parts a committer has not been involved in before, they should read the logs to see what has happened in this area before, and also read the MAINTAINERS file to see if the maintainer of this part has any special requests on how changes in the code should be made.
Core Team
The core team is elected by the committers from the pool of committers and serves as the board of directors of the FreeBSD project. It promotes active contributors to committers, assigns people to well-defined hats, and is the final arbiter of decisions involving which way the project should be heading. As of July 1st, 2004, core consisted of 9 members. Elections are held every two years.
Maintainership
Maintainership means that that person is responsible for what is allowed to go into that area of the code and has the final say should disagreements over the code occur. This involves proactive work aimed at stimulating contributions and reactive work in reviewing commits.
With the FreeBSD source comes the MAINTAINERS file that contains a one-line summary of how each maintainer would like contributions to be made. Having this notice and contact information enables developers to focus on the development effort rather than being stuck in a slow correspondence should the maintainer be unavailable for some time.
