+
+  Version 3.4.0
+  -------------
+
+  Over the last couple years we've worked very closely with the
+  Ruby Sass team to reach Sass 3.4 compatibility.
+
+  It's become clear that need to draw a line in sand with exactly
+  how exactly we can match Sass 3.4, especially in the face of
+  changes in Sass 3.5.
+
+  With this release the LibSass team is marking the completion of
+  active development on Sass 3.4 compatibility. From today we'll
+  focus our efforts on Sass 3.5 compatibility, first prioritising
+  CSS compatibility features like support for CSS custom property
+  and CSS grids.  Improves to @at-root
+
+  @at-root has mostly worked since it's introduction to LibSass but
+  there have always been issue when it was combined with conditions
+  (like @if) or mixins.  These issues were due to a fundamental
+  difference in the LibSass implementation.  The difference has
+  been addressed, so @at-root is now fully supported.
+
+  You can read more about the specifics of this issue in #2089
+
+    - Implement the Trace AST node (@xzyfer, #1585)
+    - Remove the selector stack from the CSSize visitor (@xzyfer,
+      #2091)
+    - Workaround parent selector issues with at-root (@xzyfer,
+      #2006 #2198)
+
+  * Delayed Values
+
+  Knowing when to evaluate a string, function, do concatenation, or
+  perform math is a complicated problem with many edge cases.
+  @mgreter has continued his work on improving the accuracy of
+  these decisions.
+
+    - Significant improvements to delayed values (@mgreter, #2042,
+      #2034 #2057)
+    - / interpreted as division instead of separator (@mgreter,
+      #2149)
+    - Mishandling quotes (@mgreter, #2153 #2156)
+
+  * Continued improvements to @extend
+
+  @extend is hard. With every release we get better at it and this
+  release is no exception.
+
+    - Extending inner of :not can lead to invalid css (@mgreter,
+      #2054)
+    - Segfault with @extend (@mgreter, #2051)
+    - Extending a placeholder from a media query outputs nothing
+      (@mgreter, #2150)
+    - Don't drop pseudo elements in wrapped selectors (@xzyfer,
+      #2200)
+
+  * Memory improvments
+
+  @mgreter has done some great work on improving our memory usage
+  when dealing with large maps, and lists. He's not done yet, keep
+  your eyes peeled for further improvments in upcomming releases.
+
+    - Improve memory footprint when evaluating in loops (@mgreter,
+      #2171)
+
+  * Support list functions on maps
+
+  Implementing Sass maps was my first major contribution to
+  LibSass. A couple year later I can finally all the job complete
+  with support for maps in list functions.
+
+    - Support list functions on maps (@xzyfer, #1930)
+
+  * Sourcemaps
+
+  @mgreter and @nschonni have made some significant improvements to
+  our sourcemaps. You can read more about the specifics in the bug
+  links below.
+
+    - Bugfixes for source maps (@mgreter, #2216)

+        * Don't include semicolon for statics

+      #2219)
+    - Implement source_map_file_urls option (@mgreter, #2220)
+    - Re-order the sourcemap writing to match spec (@nschonni,
