-### Default transaction isolation level
-
-Applications using asyncpg that were developed prior to CockroachDB's inclusion of
-READ COMMITTED transaction isolation may operate on the assumption that the default
-isolation level will be SERIALIZABLE. For example, 
-
-```python
-import asyncio
-
-from sqlalchemy.ext.asyncio import create_async_engine
-
-
-async def async_main():
-    engine = create_async_engine(
-        "cockroachdb+asyncpg://root@localhost:26257/defaultdb",
-    )
-    async with engine.begin() as conn:
-        result = await conn.exec_driver_sql("select version()")
-        print(result.scalar().split("(")[0])  # CockroachDB CCL v23.2.4
-        
-        result = await conn.exec_driver_sql("show transaction isolation level")
-        print(result.scalar())  # serializable
-
-
-asyncio.run(async_main())
-```
-
-With current versions of CockroachDB, the default transaction isolation level
-**for asyncpg only** is now READ COMMITTED
-
-```python
-import asyncio
-
-from sqlalchemy.ext.asyncio import create_async_engine
-
-
-async def async_main():
-    engine = create_async_engine(
-        "cockroachdb+asyncpg://root@localhost:26257/defaultdb",
-    )
-    async with engine.begin() as conn:
-        result = await conn.exec_driver_sql("select version()")
-        print(result.scalar().split("(")[0])  # CockroachDB CCL v24.3.0
-        
-        result = await conn.exec_driver_sql("show transaction isolation level")
-        print(result.scalar())  # read committed
-
-
-asyncio.run(async_main())
-```
-
-Applications that rely on the original behavior will have to add `isolation_level="SERIALIZABLE"`
-to their `create_async_engine()` call
-
-```python
-import asyncio
-
-from sqlalchemy.ext.asyncio import create_async_engine
-
-
-async def async_main():
-    engine = create_async_engine(
-        "cockroachdb+asyncpg://root@localhost:26257/defaultdb",
-        isolation_level="SERIALIZABLE",
-    )
-    async with engine.begin() as conn:
-        result = await conn.exec_driver_sql("select version()")
-        print(result.scalar().split("(")[0])  # CockroachDB CCL v24.3.0
-
-        result = await conn.exec_driver_sql("show transaction isolation level")
-        print(result.scalar())  # serializable
-
-
-asyncio.run(async_main())
