+Deprecations and Backwards Incompatible Changes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+- Default to ``canonicalize=False`` in :class:`scrapy.linkextractors.LinkExtractor`
+  (:issue:`2537`, fixes :issue:`1941` and :issue:`1982`):
+  **warning, this is technically backwards-incompatible**
+- Enable memusage extension by default (:issue:`2539`, fixes :issue:`2187`);
+  **this is technically backwards-incompatible** so please check if you have
+  any non-default ``MEMUSAGE_***`` options set.
+- ``EDITOR`` environment variable now takes precedence over ``EDITOR``
+  option defined in settings.py (:issue:`1829`); Scrapy default settings
+  no longer depend on environment variables. **This is technically a backwards
+  incompatible change**.
+- ``Spider.make_requests_from_url`` is deprecated
+  (:issue:`1728`, fixes :issue:`1495`).
