+
+### Security updates
+
+- Fixed a case where connections to Google Cloud storage would ignore the [`--external-io-disable-implicit-credentials`](../v20.1/cockroach-start.html#external-io-disable-implicit-credentials) flag to `cockroach start`. [#55091][#55091]
+
+### General changes
+
+- Reduced the memory overhead of rangefeeds (i.e., long-lived requests) which reduces the memory overhead for running [`CHANGEFEED`](https://www.cockroachlabs.com/docs/v20.2/stream-data-out-of-cockroachdb-using-changefeeds.html)s over large tables. [#54632][#54632]
+
+### Bug fixes
+
+- Fixed a bug where columns used in an [index](../v20.1/indexes.html) which contained the columns of a [foreign key](../v20.1/foreign-key.html) as a prefix could lead to all of the index columns being set to _NULL_ or the default value on cascade. [#54543][#54543]
+- Fixed a bug causing servers to crash with the message "committed txn with writeTooOld". Versions below 20.1.4 are susceptible to this bug. Versions 20.1.4+ will not crash, but instead print messages to the log files. [#54282][#54282]
+- Fixed a rare bug which can lead to index backfills failing in the face of [transaction restarts](../v20.1/transactions.html#transaction-retries). [#54859][#54859]
+- Fixed a race condition propagating post-query metadata in the [vectorized execution engine](../v20.1/vectorized-execution.html). [#55168][#55168]
+- Fixed a bug causing 20.1 nodes to not be able to serve [follower reads](../v20.1/follower-reads.html) in mixed-version 19.2/20.1 clusters. [#55089][#55089]
+- The first timing column in the trace.txt file collected as part of a [statement diagnostics bundle](../v20.1/explain-analyze.html#debug-option) has been fixed.

 `--cert-principal-map` | <span class="version-tag">New in v20.1:</span> A comma-separated list of `cert-principal:db-principal` mappings used to map the certificate principals to IP addresses, DNS names, and SQL users. This allows the use of certificates generated by Certificate Authorities that place restrictions on the contents of the `commonName` field. For usage information, see [Create Security Certificates using Openssl](create-security-certificates-openssl.html#examples).
