 * Log backup supports GCS and Azure Blob Storage as backup storage.
 * Log backup is now compatible with the `exchange partition` DDL.
 * The SQL statement `ALTER TABLE ...SET TiFLASH MODE ...` previously used for enabling [fastscan](/develop/dev-guide-use-fastscan.md) is deprecated, and replaced by the system variable [`tiflash_fastscan`](/system-variables.md#tiflash_fastscan-new-in-v630). When you upgrade from v6.2.0 to v6.3.0, all FastScan settings in v6.2.0 will become invalid, but will not affect the normal reading of data. In this case, you need to configure the variable [`tiflash_fastscan`](/system-variables.md#tiflash_fastscan-new-in-v630) to enable or disable FastScan. When you upgrade from an earlier version to v6.3.0, the FastScan feature is not enabled by default for all sessions to keep data consistent.

 TiFlash conducts real-time replication of data in the TiKV nodes at a low cost that does not block writes in TiKV. Meanwhile, it provides the same read consistency as in TiKV and ensures that the latest data is read. The Region replica in TiFlash is logically identical to those in TiKV, and is split and merged along with the Leader replica in TiKV at the same time.

 - Support upgrading the versions of TiDB Binlog, TiCDC, TiFlash, and other components.
-- When upgrading TiFlash deployed under the Linux AMD64 architecture from versions earlier than v6.3.0 to v6.3.0 and later versions, ensure that the CPU supports AVX2 instruction sets. For details, see the description in [v6.3.0 Release Notes](/releases/release-6.3.0.md#others).
+- When upgrading TiFlash from versions earlier than v6.3.0 to v6.3.0 and later versions, note that the CPU must support AVX2 instruction sets under the Linux AMD64 architecture and ARMv8 instruction sets under the Linux ARM64 architecture. For details, see the description in [v6.3.0 Release Notes](/releases/release-6.3.0.md#others).
 - For detailed compatibility changes of different versions, see the [Release Notes](/releases/release-notes.md) of each version. Modify your cluster configuration according to the "Compatibility Changes" section of the corresponding release notes.
 - For clusters that upgrade from versions earlier than v5.3 to v5.3 or later versions, the default deployed Prometheus will upgrade from v2.8.1 to v2.27.1. Prometheus v2.27.1 provides more features and fixes a security issue. Compared with v2.8.1, alert time representation in v2.27.1 is changed. For more details, see [Prometheus commit](https://github.com/prometheus/prometheus/commit/7646cbca328278585be15fa615e22f2a50b47d06) for more details.
