Version 0.19.3
Ensures WP-CLI doesn't use cached WP minor upgrade partial archives in the major version upgrade process (pull request).
Since v0.17.0 (pull request), WP-CLI mistakenly cached partial archives in a lossy manner, which could result in a major version upgrade only upgrading the files from the cached partial archive.
Use wp core verify-checksums
to make sure a given WordPress install has the correct copy of each file. If it doesn't verify, use wp core download --version=$(wp core version) --force
to re-install WordPress.
