+h1. Deprecated extensions
+
+The following extensions are deprecated because equivalent features are part of the CWL v1.1 standard.

+
+h2. cwltool:LoadListingRequirement
+
+For CWL v1.1 scripts, this is deprecated in favor of "loadListing":https://www.commonwl.org/v1.1/CommandLineTool.html#CommandInputParameter or "LoadListingRequirement":https://www.commonwl.org/v1.1/CommandLineTool.html#LoadListingRequirement
+
+In CWL v1.0 documents, the default behavior for Directory objects is to recursively expand the @listing@ for access by parameter references an expressions. For directory trees containing many files, this can be expensive in both time and memory usage. Use @cwltool:LoadListingRequirement@ to change the behavior for expansion of directory listings in the workflow runner.

+table(table table-bordered table-condensed).
+|_. Field |_. Type |_. Description |
+|loadListing|string|One of @no_listing@, @shallow_listing@, or @deep_listing@|
+
+*no_listing*: Do not expand directory listing at all. The @listing@ field on the Directory object will be undefined.
+
+*shallow_listing*: Only expand the first level of directory listing. The @listing@ field on the toplevel Directory object will contain the directory contents, however @listing@ will not be defined on subdirectories.
+
+*deep_listing*: Recursively expand all levels of directory listing. The @listing@ field will be provided on the toplevel object and all subdirectories.
+
+h2. arv:ReuseRequirement
+
+For CWL v1.1 scripts, this is deprecated in favor of "WorkReuse":https://www.commonwl.org/v1.1/CommandLineTool.html#WorkReuse .

+
+Set an upper limit on the execution time of a CommandLineTool or ExpressionTool. A tool execution which exceeds the time limit may be preemptively terminated and considered failed. May also be used by batch systems to make scheduling decisions.
