+Version 2.43.0
+- This is the start of the 2.43 development series, and you bet we are
+  doing extensive changes!
+- Many, many thanks to Jordan Petridis for keeping our Continuous
+  Infrastructure updated all the time, and for emergency fixes when
+  they were necessary.
+- As part of the Summer of Code 2018, Ivan Molodetskikh is porting the
+  filter effects to Rust.  These are done so far:  core filters
+  infrastructure, feComposite, feMerge, feOffset.  The only remaining
+  SVG elements done in C pertain to filter effects, and Ivan is taking
+  care of them.
+- The feComposite filter now operates in linear RGB space, for better
+  spec compliance.  We transform back to SRGB for the final results
+  (see issue #275 for pending work on fully supporting this
+  elsewhere).
+- Filters now compute their bounds to floating-point values, instead
+  of clipping them to integers.
+- The text, tspan, tref elements are now in Rust (Paolo Borelli).
+- Text rendering should be better.  We now perform text measurement
+  operations with the actual affine transformation that the text will
+  use in the end.  This should give Pango/Freetype a better chance of
+  doing scale-appropriate hinting.
+- The basic styling infrastructure has moved to Rust (Paolo Borelli,
+  Federico Mena).  We don't use the old and limited cascading code
+  anymore.  We also audited which CSS properties are supposed to
+  inherit automatically or not; this should be working per the SVG
+  spec now.  Special thanks to Paolo for doing the largest part of the
+  work in moving the style data to Rust; this was a painstaking,
+  months-long process of constant refactoring.
+- The internals of the drawing infrastructure and bounding-box
+  computation are now done in Rust (Paolo Borelli).
+- Element creation from the parsing stage is now in Rust (Saurav
+  Sachidanand).
+- Clipping and Masking are now done in Rust (Paolo Borelli).
+- Our tests now include the full Adwaita icon theme, so it doesn't
+  break.
+- Fix: #241 - feDistantLight and feSpotLight now work again.
+- Fix: #282 - feComposite is fixed not to overwrite the source image
+  in some cases; this fixes drop shadows generated from Inkscape (Ivan
+  Molodetskikh).
+- We have the beginnings of Windows CI, courtesy of Guillaume Gomez.
+- Changes from 2.42.4:
+- Fix: elements with systemLanguage attributes without variants now
+  work better (Paolo Borelli).
+- gitlab#227 - Fix: we now catch negative values in stroke-dasharray
+  properties instead of leaving the cairo_t in an error state.
+- gitlab#228 - Fix: empty transform attribute now correctly yields an
+  identity transform (Dmitry Kontsevoy).
+- Fix possible crash on invalid gradient references.
+- Make robust against patterns and gradients with no children.
+- Lots of code cleanups and refactorings (Jordan Petridis, Dmitry
+  Kontsevoy, Ivan Molodetskikh).
+- Code moved to Rust: low-level path and PangoLayout drawing, "switch"
+  element (Paolo Borelli).
+- New Rust dependencies: float_cmp, pangocairo crates.
+- We now require Rust 1.21 or later.
+- Changes from 2.42.5:
+- #276 - rsvg_handle_render_cairo() will now refuse to render if the
+  cairo_t passed to it is in an error state.  Fixes a panic in the
+  cairo-dock program.
+- #206 - The test suite now writes test artifacts to tests/output
+  instead of /tmp (Saurav Sachidanand).
