- Starting from v8.0.0, the [`tidb_disable_txn_auto_retry`](/system-variables.md#tidb_disable_txn_auto_retry) system variable is deprecated, and TiDB no longer supports automatic retries of optimistic transactions. As an alternative, when encountering optimistic transaction conflicts, you can capture the error and retry transactions in your application, or use the [Pessimistic transaction mode](/pessimistic-transaction.md) instead.
- Starting from v8.0.0, TiDB no longer supports the TLSv1.0 and TLSv1.1 protocols. You must upgrade TLS to TLSv1.2 or TLSv1.3.

The [`duplicate-resolution`](/tidb-lightning/tidb-lightning-configuration.md) parameter for the old version of conflict detection will be removed in v8.5.0.
