+As the team continues to work on the next development iteration of Debezium 3.5, we're pleased to report the immediate availability of Debezium **3.4.1.Final**, the first maintenance release of the 3.4 release stream.
+
++++<!-- more -->+++
+
+In this post, we're going to take a deep dive into the improvements and fixes in this maintenance release of Debezium, highlighting any features or noteworthy changes.
+As always, we recommend you read the link:/releases/3.4/release-notes#release-3.4.1-final[release notes] to learn more about all the bugs that were fixed, update procedures, and more.

+== New features and improvements
+
+=== Debezium for Oracle
+
+==== Dynamic Archive Destination Support
+
+When an Oracle primary server fails over to a standby server, it's very likely that Debezium has not read all the changes from the transaction logs on the primary when the failover occurs.
+As a result, when the standby is promoted to the primary, it will begin to write changes to a new archive destination.
+
+When Debezium reconnects to the newly promoted primary, Debezium will attempt to locate where it left off, and fail to start.
+This failure to start issue is a result of the fact that the primary changes that were not consumed by Debezium exist in the archive destination specific to the standby system being in standby-mode, not primary-mode.
+
+To solve this issue, the `archive.destination.name` configuration property can be supplied a series of comma-separated archive destination names.
+When multiple names are supplied, Debezium will gather logs across all configured destinations and perform a deduplication pass by redo thread and log sequence pairs.
+This deduplication pass will prefer logs in earlier destinations from logs in later destinations that have the same thread and sequence pair.
+
+With this change, Debezium is significantly more fault-tolerant during a primary to standby failover and recovers without the need for a snapshot, as long as there is no data loss at the transaction log level between the two systems (https://github.com/debezium/dbz/issues/1246[debezium/dbz#1246]).
