+Fixed or Mitigated Bugs
+-----------------------
+
+Reported via GitHub:
+
+  - #65 ("Normal for the prism's bezier spline mode is reversed from other
+    spline types & lathe uses.")
+  - #292 ("Port of FS227 - Fixed Vector Limitations")
+  - #317 ("Boost 1.65.0 incompatibility")
+
+Reported via the Newsgroups:
+
+  - <[email protected]>
+    (2017-11-05, povray.newusers, "orthographic camera and conic_sweep object")
+    Sides of a `conic_sweep` prism become invisible when viewed head-on using
+    an orthographic camera.
+
+Miscellaneous:
+
+  - Fix `interior_texture` for text objects (as mentioned in GitHub issue #65)
+  - Eliminated use of deprecated C++ `register` keyword (except in 3rd party
+    libraries bundled with the POV-Ray source code).
+
+Changed Behaviour
+-----------------
+
+  - Any new behaviour formerly activated by `#version 3.71` now requires
+    `#version 3.8` (or higher); specifying `#version 3.71` will trigger a
+    corresponding warning.
+  - Some defaults have been changed (requires `#version 3.8` as the _very first_
+    statement of the scene, or a corresponding command line / INI setting):
+      - The pigment now defaults to plain white.
+      - `ambient` now defaults to 0.0 instead of 0.1.
+      - The camera `right` vector length now defaults to the output image aspect
+        ratio (presuming square pixels) instead of 1.33.
+  - Minor changes have been made to the benchmark scene. New benchmark version
+    is 2.03.
+
+Other Noteworthy
+----------------
+
+  - The source code now requires a C++11-compliant compiler.
+  - The Unix build process now officially requires Autoconf 2.68 or later.
+  - Added `--generation` command-line switch to POV-Ray for Unix, which will
+    cause POV-Ray to print its abbreviated version number to standard output.
+  - To simplify version number housekeeping, the file `unix/VERSION` is now
+    created on the fly by the `unix/prebuild.sh` script, and has been dropped
+    from the repository. To retrieve version information from the source
+    package, use one of the new `get-source-version.*` scripts provided in
+    `tools/unix/` and `tools/windows/`, respectively.
+
+
+Changes between 3.7.1-beta.9 and 3.7.1-rc.1
+===========================================
+
+Fixed or Mitigated Bugs
+-----------------------
+
+Miscellaneous:
+
+  - Fixed a bug that broke builds without optimized noise.
+  - Fixed an issue in optimized noise when building on Unix with C++ compiler
+    switches disabling any of the relevant enhanced instruction sets (e.g.
+    `CXXFLAGS=-mno-fma`).
