Version Number Meaning

The ProxyToys project follows strict rules that govern its use of version numbers. The version number of a release indicates how that release is compatible with previous and future releases.

Version numbers have the form major.minor.patch. The major version number identifies the API version. A release that changes the API in a way that breaks backwards compatibility will increment the major version number and reset the minor and patch versions to zero. The minor version number identifies the backwards compatible revision of the API. An API version that adds new elements to the API will have the same major version, increment the minor version and set the patch version to zero. The patch version number identifies revisions that do not change the API. A release that fixes bugs or refactors implementation details without changing the API will have the same minor and major versions as the previous release and increment the patch number.

A hypothetical example:

1.0.0First release
1.0.1Improves Javadoc comments
1.1.0Adds new API elements
1.2.0Adds new API elements, deprecates some API elements
1.2.1Fixes bugs
2.0.0Incompatible API changes, removes API elements deprecated by version 1.2.0.
2.1.0Adds new API elements

Release Candidates

Before a new major or minor release, ProxyToys will make release candidate (RC) packages available so that users can test them against their own code. There will be one or more release candidates given the version major.minor.0 RCn, where the major and minor version numbers identify the upcoming release and RC1 identifies the first candidate release, RC2 the second, and so on.

A release candidate does not guarantee backward compatability with new API features introduced by any previous RC of the same upcoming version. A major version RC can change/remove API features introduced in a previous RC for the same major version; a minor version RC can change API features introduced by any previous RC of the same upcoming minor version but guarantees backward compatability with the previous minor version.

Internal Classes

Many classes are for internal use only and not designed to be used by end users. These are exempt from the versioning rules above.

Such classes are clearly marked as internal in the source code headers and are excluded from the published JavaDoc.

Versioning and Deprecation

A minor release might deprecate some API features. Deprecated features will not actually be removed until the next major release. A release will never remove API features that have not been deprecated in a previous release.
