+ruby-ethon (0.9.0-1+rpi1) buster-staging; urgency=medium
+
+  [Changes taken from 0.9.0-1ubuntu1 by Steve Langasek]
+  * Bump dependency from libcurl3 to libcurl4 for the openssl1.1 transition.
+    Note that this changes the ABI with respect to SSL_CTX objects;
+    consumers of ruby-ethon must now switch to using OpenSSL 1.1 objects
+    instead of OpenSSL 1.0 if they use curl_easy_setopt(SSL_CTX_FUNCTION).
