 # ChangeLog for crypton-x509-system
 
+## 1.9.0
+
+* Using "ram" instead of "memory"
+  [#29](https://github.com/kazu-yamamoto/crypton-certificate/pull/29)
+
+## 1.8.0
+
+* Depend indirectly on package `time-hourglass`, rather than `hourglass`. Date
+  and time-related types and classes are now those from the former package.
+  [#18](https://github.com/kazu-yamamoto/crypton-certificate/pull/18)
+* Depend indirectly on package `crypton-asn1-types >= 0.4.1` rather
+  than `asn1-types`. ASN.1-related types and classes are now those from the
+  former package.
+
 ## 1.6.8
 
 * Prefer OpenSSL env vars: SSL_CERT_FILE and SSL_CERT_DIR
