Release version 1.2.0

[jeffpaul]

This issue is for tracking changes for the 1.2.0 release. Target release date: TBD July 2020.

Pre-release steps

• IDEAL: add/update screenshot files and references in readme.txt/README.md for new functionality

Release steps

• Branch: Starting from develop, cut a release branch named release/1.2.0 for your changes.
• Version bump: Bump the version number in maps-block-apple.php, readme.txt, and package.json if it does not already reflect the version being released. Update both the plugin "Version:" property and the plugin MAPS_BLOCK_APPLE_VERSION constant in maps-block-apple.php.
• Changelog: Add/update the changelog in CHANGELOG.md and readme.txt.
• Props: update CREDITS.md with any new contributors, confirm maintainers are accurate.
• New files: Check to be sure any new files/paths that are unnecessary in the production version are included in .gitattributes.
• Readme updates: Make any other readme changes as necessary. README.md is geared toward GitHub and readme.txt contains WordPress.org-specific content. The two are slightly different.
• Merge: Make a non-fast-forward merge from your release branch to develop (or merge the pull request), then do the same for develop into trunk (git checkout trunk && git merge --no-ff develop). trunk contains the latest stable release.
• Test: Run through common tasks while on trunk to be sure it functions correctly.
• Push: Push your trunk branch to GitHub (e.g. git push origin trunk).
• Release: Create a new release, naming the tag and the release with the new version number, and targeting the trunk branch. Paste the changelog from CHANGELOG.md into the body of the release and include a link to the closed issues on the milestone.
• SVN: Wait for the GitHub Action to finish deploying to the WordPress.org repository. If all goes well, users with SVN commit access for that plugin will receive an emailed diff of changes.
• Check WordPress.org: Ensure that the changes are live on https://wordpress.org/plugins/simple-podcasting/. This may take a few minutes.
• Close the milestone: Edit the milestone with release date (in the Due date (optional) field) and link to GitHub release (in the Description field), then close the milestone.
• Punt incomplete items: If any open issues or PRs which were milestoned for 1.2.0 do not make it into the release, update their milestone to 1.3.0, or Future Release.
