Reviewing changes to add to CHANGELOG.org

Examine the output of git log since the last time the Change Log was updated and narrow it down to notable commits, e.g. new variables, bug fixes, breaking changes, etc. Write a few sentences describing the change and how it affects users going forward.

git log --pretty=format:"%s" ${PREV_VERSION}...${VERSION}

Updating project metadata

• Increment copyright years, if needed
• Set the Version header
• Set jupyter-version in file:jupyter-base.el
