-+- Stable release DAPS 3.3.0:
-+
-+* New features:
-+  - DocBook table validation is now enabled by default as part of
-+    validation and building (#532)
-+  - Improved validation to always check XML validity, tables,
-+    images, and IDs, rather than stopping after the first issue
-+    occurs
-+  - Set up Poppins font in FOP config delivered with DAPS
-+
-+* Bug fixes:
-+  - Fixed validation failures occurring because `--verbose` was set
-+  - Fixed xml-wellformedness check to use a non-zero exit code
-+    when entity definitions are missing (#539)
-+  - Improved image check during validation to check within context
-+    of entire set, not just current root ID (#627)
-+  - Fixed output of missing/duplicated image list displayed during
-+    build (#634)
-+  - Fixed paths to entity files in `unpack-locdrop`
-+  - Fixed output of `daps -v` when there is no XSL-FO formatter
-+    installed (#622)
-+  - Fixed `daps spellcheck --help` output
-+  - Improved messages for `unpack-locdrop` and other subcommands
-+
-+* Removed features:
-+  - Removed unused `process-xrefs` and `checkconformance`
-+    stylesheets (#612)
-+
-+* Repository changes:
-+  - Integrated Python tooling and tests for `xml-wellformed` and
-+    `getentityname`
