+1.1.0 (2021-04-26)
+------------------
+
+- [NEW] Implemented the ``dehumanize`` method for ``Arrow`` objects. This takes human readable input and uses it to perform relative time shifts, for example:
+
+.. code-block:: python
+
+    >>> arw
+    <Arrow [2021-04-26T21:06:14.256803+00:00]>
+    >>> arw.dehumanize("8 hours ago")
+    <Arrow [2021-04-26T13:06:14.256803+00:00]>
+    >>> arw.dehumanize("in 4 days")
+    <Arrow [2021-04-30T21:06:14.256803+00:00]>
+    >>> arw.dehumanize("in an hour 34 minutes 10 seconds")
+    <Arrow [2021-04-26T22:40:24.256803+00:00]>
+    >>> arw.dehumanize("hace 2 años", locale="es")
+    <Arrow [2019-04-26T21:06:14.256803+00:00]>
+
+- [NEW] Made the start of the week adjustable when using ``span("week")``, for example:
+
+.. code-block:: python
+
+    >>> arw
+    <Arrow [2021-04-26T21:06:14.256803+00:00]>
+    >>> arw.isoweekday()
+    1 # Monday
+    >>> arw.span("week")
+    (<Arrow [2021-04-26T00:00:00+00:00]>, <Arrow [2021-05-02T23:59:59.999999+00:00]>)
+    >>> arw.span("week", week_start=4)
+    (<Arrow [2021-04-22T00:00:00+00:00]>, <Arrow [2021-04-28T23:59:59.999999+00:00]>)
+
+- [NEW] Added Croatian, Latin, Latvian, Lithuanian and Malay locales.
+- [FIX] Internally standardize locales and improve locale validation. Locales should now use the ISO notation of a dash (``"en-gb"``) rather than an underscore (``"en_gb"``) however this change is backward compatible.
+- [FIX] Correct type checking for internal locale mapping by using ``_init_subclass``. This now allows subclassing of locales, for example:
+
+.. code-block:: python
+
+    >>> from arrow.locales import EnglishLocale
+    >>> class Klingon(EnglishLocale):
+    ...     names = ["tlh"]
+    ...
+    >>> from arrow import locales
+    >>> locales.get_locale("tlh")
+    <__main__.Klingon object at 0x7f7cd1effd30>
+
+- [FIX] Correct type checking for ``arrow.get(2021, 3, 9)`` construction.
+- [FIX] Audited all docstrings for style, typos and outdated info.
+
