The following describes the most significant changes which occurred in HTX between versions V1.0 and V1.1.
document.htx/htx.index
This means that if a document is removed from a library, its index file is automatically removed as well. This avoids the need for other library maintenance software to know about HTX index files.
The old "docname.index" files are no longer used and may be removed. New index files will then be generated when hlink is next run.
This means that by default HTX can now locate both its own and other Starlink documentation even if it is not installed in the standard place (i.e. under the /star directory).
