Unavailable Versions

Some versions have known problems and are strongly discouraged. For new projects, use the latest version directly.

Versions that are not recommended

Version	Problem
v4.0.0	Forces a dependency on MyBatis and others.
v3.6.0 / v3.6.1	Broken dynamic resolution of @DS("#header.xx"); harmless if you do not use it.
v3.3.3	Serious bug: the Advisor fails to start, so datasource switching stops working.
v3.3.0	Forces a dependency on Seata at startup after packaging.
v3.1.0	Uses NamedInheritableThreadLocal, which breaks datasource switching under high concurrency.
v2.3.3	Nested datasource switching falls back to the primary datasource.
v2.3.2 / v2.3.1 / v2.2.2	Contain bugs that can no longer be reproduced; avoid them.
