These security issues were fixed:
CVE-2018-0732: During key agreement in a TLS handshake using a DH(E)
 based ciphersuite a malicious server could have sent a very large prime
 value to the client. This caused the client to spend an unreasonably
 long period of time generating a key for this prime resulting in a hang
 until the client has finished. This could be exploited in a Denial Of
 Service attack (bsc#1097158)

Make problematic ECDSA sign addition length-invariant

Add blinding to ECDSA and DSA signatures to protect against side channel
 attacks

These non-security issues were fixed:
When unlocking a pass phrase protected PEM file or PKCS#8 container, we
 now allow empty (zero character) pass phrases.

Certificate time validation (X509_cmp_time) enforces stricter compliance
 with RFC 5280. Fractional seconds and timezone offsets are no longer
 allowed.

Fixed a text canonicalisation bug in CMS

Add openssl(cli) Provide so the packages that require the openssl binary
 can require this instead of the new openssl meta package (bsc#1101470)");
