+# shFlags 1.2.3 Release Notes
+
+https://github.com/kward/shflags
+
+## Preface
+
+This document covers any known issues and workarounds for the stated release of
+shFlags.
+
+## Release info
+
+This is a minor bug fix and cleanup release.
+
+There were several minor changes thanks to feedback from a major code review by
+[James Youngman](https://www.linkedin.com/in/jamesyoungman/). Thank you!
+
+Please see the `CHANGES-1.2.md` file for a complete list of changes.
+
+### Notable changes
+
+None.
+
+### Notable bug fixes
+
+Fixed the examples to work again with the new code structure. These broke when
+the code was refactored for GitHub.
+
+## General info
+
+### The unit tests
+
+shFlags is designed to work on as many environments as possible, but not all
+environments are created equal. As such, not all of the unit tests will succeed
+on every platform. The unit tests are therefore designed to fail, indicating to
+the tester that the supported functionality is not present, but an additional
+test is present to verify that shFlags properly caught the limitation and
+presented the user with an appropriate error message.
+
+shFlags tries to support both the standard and enhanced versions of `getopt`. As
+each responds differently, and not everything is supported on the standard
+version, some unit tests will be skipped (i.e. ASSERTS will not be thrown) when
+the standard version of `getopt` is detected. The reason being that there is no
+point testing for functionality that is positively known not to exist. A tally
+of skipped tests will be kept for later reference.
+
+### Standard vs Enhanced getopt
+
+Here is a matrix of the supported features of the various `getopt` variants.
+
+Feature                                 | std | enh
+--------------------------------------- | --- | ---
+short option names                      | Y   | Y
+long option names                       | N   | Y
+spaces in string options                | N   | Y
+intermixing of flag and non-flag values | N   | Y
+
+## Known Issues
+
+The `getopt` version provided by default with all versions of Mac OS X (up to
+and including 10.13.0) and Solaris (up to and including Solaris 10 and
+OpenSolaris) is the standard version.
+
+## Workarounds
+
+The Zsh shell requires the `shwordsplit` option to be set and the special
+`FLAGS_PARENT` variable must be defined. See `src/shflags_test_helpers` to see
+how the unit tests do this.
