# extractFeaturesFromReleaseNotes.py
#
# Read the release notes - docs/release-notes.md - and generate text
# for pasting in to individual documentation pages, to indicate which
# versions recent features were released in.
#
# Using the output of the file is easier than manually constructing
# the text to paste in to documentation pages.
#
# One way to use this:
# - run this script, saving the output to some temporary file
# - diff this output with the actual release notes page
# - the differences are Markdown text that can be pasted in to the
# appropriate documentation pages in the docs/ directory.
# - each release also has a github link to show which documentation files
# were changed in it.
# This can be helpful to see which documentation pages
# to add the 'Introduced in Catch ...' snippets to the relevant pages.
