-## 3.0.0 - TBD
+## 3.0.2 - 2019-05-26
+
+### Fixed
+
+* Issues #432 and #434 have been fixed. When processing content types,
+  such as entries in `source/_posts/*`, Sculpin will now skip certain
+  files.
+  * "hidden" files (beginning with a `.`) will be skipped silently.
+    * This helps suppress files like `.DS_Store`.
+  * files which aren't recognized by any registered Formatter will be
+    skipped with a "Skipped ..." message.
+    * This helps combat strange behaviour for files with no extension.
+
+## 3.0.1 - 2019-04-17
+
+### Added
+
+* Thanks to Rami Jumaah and Christian Riesen, Pages can now refer to
+  their own relative pathname and filename using `page.relative_pathname`
+  and `page.filename`. This can be useful for implementing an "Edit This
+  Page" link directly to a GitLab or GitHub VCS URL.
+
+### Changed
+
+* Boilerplate is now generated by default when using `content:create`
+  * Use `--dry-run`/`-d` to suppress the creation of these files
+  * Note that the YAML content type definition still needs to be added
+    by hand to your `app/config/sculpin_kernel.yml` file
+  * Taxonomy-related boiler plate files now default to using the default
+    layout instead of no layout at all. This should result in prettier
+    output.
+
+### Deprecated
+### Removed
+### Fixed
+
+* ProxySourceCollection now uses the StableSort algorithm from Martijn
+  van der Lee to ensure stable sorting results, which will eliminate
+  some of the issues reported in bug #308 that were causing `generate`
+  to constantly repeat in watch mode.
