 What's New
 ----------
 
-This is the fourth snapshot release of OQS-OpenSSL_1\_1\_1-stable.  It is based on OpenSSL 1.1.1g.
+This is the fifth snapshot release of OQS-OpenSSL_1\_1\_1-stable.  It is based on OpenSSL 1.1.1k.
 
-- Uses the updated NIST Round 2 submissions added to liboqs 0.4.0, as described in the [liboqs release notes](https://github.com/open-quantum-safe/liboqs/blob/main/RELEASE.md).
+- Removes algorithms from NIST PQC Round 2 that did not advance to Round 3: NewHope, ThreeBears, MQDSS, qTesla.
+- Updates algorithms to those used in liboqs 0.5.0, as described in the [liboqs release notes](https://github.com/open-quantum-safe/liboqs/blob/main/RELEASE.md).
+- Adds HQC, NTRUPrime.
+- Improvements to continuous integration testing and build process, including building of shared libraries.
+- Change format of hybrid key exchange in TLS 1.3 to follow https://tools.ietf.org/html/draft-ietf-tls-hybrid-design-01
 
-Deprecations
-------------
+Previous release notes
+----------------------
 
-As a result of NIST's announcement of Round 3 of the Post-Quantum Cryptography Standardization Project, this is the last release of OQS-OpenSSL that contain algorithms from Round 2 that are not Round 3 finalists or alternate candidates. Those algorithms will be removed in the next release. The algorithms in question are: NewHope, ThreeBears, MQDSS, and qTesla. These algorithms are considered deprecated within OQS-OpenSSL will receive no updates after this release.
