 ----------
 
+8.1.0
+=====
+
+* New module ``bundle_utils.py`` that is intended for schema-respecting worksheets ("metadata bundle").
+  There are various modular bits of functionality here, but the main entry point here is:
+
+  * ``load_items`` to load data from a given table set, doing certain notational canonicalizations, and
+    checking that things are in the appropriate format.
+
+* In ``common.py``, new hint types:
+
+  * ``CsvReader``
+  * ``JsonSchema``
+  * ``Regexp``
+
+* In ``lang_utils.py``:
+
+  * New arguments ``just_are=`` to ``there_are`` get verb conjugation without the details.
+
+  * Add "while" to "which" and "that" as clause handlers in the string pluralizer
+    (e.g., so that "error while parsing x" pluralizes as "errors while parsing x")
+
+* In ``misc_utils.py``, miscellaneous new functionality:
+
+  * New class ``AbstractVirtualApp`` that is either an actual VirtualApp or can be used to make mocks
+    if the thing being called expects an ``AbstractVirtualApp`` instead of a ``VirtualApp``.
+
+  * New function ``to_snake_case`` that assumes its argument is either a CamelCase string or snake_case string
+    and returns the snake_case form.
+
+  * New function ``is_uuid`` (migrated from Fourfront)
+
+  * New function ``pad_to``
+
+  * New class ``JsonLinesReader``
+
+* In ``qa_checkers.py``:
+
+  * Change the ``VERSION_IS_BETA_PATTERN`` to recognize alpha or beta patterns. Probably a rename would be better,
+    but also incompatible. As far as I know, this is used only to not fuss if you haven't made a changelog entry
+    for a beta (or now also alpha).
+
+* New module ``sheet_utils.py`` for loading workbooks in a variety of formats, but without schema interpretation.
+
+  A lot of this is implementation classes for each of the kinds of files, but the main entry point
+  is intended to be ``load_table_set`` if you are not working with schemas. For schema-related support,
+  see ``bundle_utils.py``.
+
+* New module ``validation_utils.py`` with these facilities:
+
+  * New class ``SchemaManager`` for managing a set of schemas so that programs asking for a schema by name
+    only download one time and then use a cache. There are also facilities here for populating a dictionary
+    with all schemas in a table set (the kind of thing returned by ``load_table_set`` in ``sheet_utils.py``)
+    in order to pre-process it as a metadata bundle for checking purposes.
+
+  * New functions:
+
+    * ``validate_data_against_schemas`` to validate that table sets (workbooks, or the equivalent) have rows
+      in each tab conforming to the schema for that tab.
+
+    * ``summary_of_data_validation_errors`` to summarize the errors obtained from ``validate_data_against_schemas``.
