Margin notes in this document give information about the
type of difference between T3.0 and previous versions of
T. There are seven categories of difference:
- Fixed
- indicates errors or bugs in previous releases
that have been fixed.
- Extended
- indicates that some additional functionality
has been added to the feature thus marked.
- Added
- indicates some additional functionality
that has been added to the language.
- Experimental
- indicates new features of the language
which are included on an experimental basis. Experimental
features may be removed from the language at some future
release.
- Changing
- indicates a change in functionality. The
previous functionality is supported in the current
release but will be removed in some future release.
Any code which relies on aspects of the language which
are changing should be modified as soon as possible.
- Changed
- indicates an incompatibility between
T3.0 and previous versions of T. Code which uses
a changed feature will either not work in T3.0
or will not work in previous versions of T.
- Removed
- indicates functionality that has been
removed from the current release, and is no longer
supported. Any code which relies on removed features
will no longer work.
