Version guide

1.5.13

New feature

• Add support for Spring Boot 3.x.

1.5.12

Optimization

• Improve log output.

1.5.11

Optimization

• Improve Redis log output.

• Optimize Lettuce primary/secondary database connection strategy during breakdowns: read/write splitting strictly depends on both primary and secondary databases; other read/write strategies depend only on the current database.

New feature

• Add support to control whether exceptions from the secondary Redis database are thrown.

  Add the startup parameter -Dmsha.standby.throw.disable=true to suppress secondary database exceptions.
  By default, exception throwing behavior is determined automatically based on the read/write strategy.

• Lettuce supports a built-in connection pool.

  The built-in connection pool starts automatically to improve performance if common-pool2 is included.
  If common-pool2 is added in pom.xml, use the startup parameter -Dmsha.redis.pool.disable=true to disable the automatic connection pool.

1.5.10
