* lacme: new flag `--force`, which aliases to `--min-days=-1`, i.e.,
forces renewal regardless of the expiration date of existing
certificates.
+ * Remove decomissioned intermediate CAs Authority X3 and X4 from the
+ bundle.
+ * Remove cross-signed intermediate CAs from the bundle and add the
+ (self-signed) ISRG Root X1 and X2 instead. This allows us to fully
+ validate provided X.509 chains using that self-contained bundle,
+ regardless of which CAs is marqued as trusted under /etc/ssl/certs.
+ This change bumps the minimum OpenSSL version to 1.1.0.
+ Improve nginx/apache2 snippets for direct serving of challenge files
(with the new 'challenge-directory' logic symlinks can be disabled).
