But a fresh build - 9J56 - went to developers yesterday.
According to the release notes (as published by World of Apple), 9J56 contains changes in five areas.
Two of them are related to networking, one to Bluetooth, and two to crash reporting and logging.
Networking and Bluetooth have been a focus area throughout the 10.5.7 development process.
World of Apple also points out that four of the six 10.5.x releases - including the three most recent - have appeared on Mondays.
So maybe next week?
