# 4.0.x version

LATEST_4_0 = V_4_0_0

# 4.1.x version
V_4_1_0 = KafkaVersion("4.1.0")
V_4_1_1 = KafkaVersion("4.1.1")
LATEST_4_1 = V_4_1_1

# 4.2.x version
V_4_2_0 = KafkaVersion("4.2.0")
V_4_2_1 = KafkaVersion("4.2.1")
LATEST_4_2 = V_4_2_1

# 4.3.x version
V_4_3_0 = KafkaVersion("4.3.0")
LATEST_4_3 = V_4_3_0


Review comment (suggestion):
Seems this is unused. We would only need to add this after we release AK 4.3.0, and only for `trunk / 4.4.0-SNAPSHOT` version.
