+- We can now detect licenses using custom license texts and license rules.
+  These can be provided as a one off in a directory or packaged as a plugin
+  for consistent reuse and deployment. There is an option "--additional-directory"
+  with the "scancode-reindex-licenses" command and also a new "--only-builtin"
+  option to only use the builtin licenses to build the cache.

+- Scancode LICENSE and RULE files now also contain their data as YAML frontmatter,
+  which previously used to be in their respective YAML files. This reduces number of
+  files in those directories, 'rules' and 'licenses' to half. Git line history is
+  preserved for the files.
+
+- A new command line option "--get-license-data" is added to dump license data in
+  JSON, YAML and HTML formats, and also generates a local index and a static website
+  to view the data. This will essentially be an API/way to get scancode license data
+  as opposed to just reading the files.
