Developers on Saturday were provided with Mac OS X 10.5.7 build 9J34, which represents the foruth widely distributed pre-release of the upcoming maintance and security update since the company began testing the software externally late last month.
In addition to speech dictionary improvements that will better Leopard's text-to-speech capabilities, the latest build included eight additional bug fixes over the previously seeded build 9J30, bringing the total number of code corrections expected as part of Mac OS X 10.5.7 to over 90.
Among those tweaks were fixes to color corruption issues, sleep-related anomalies, and a problem with syncing Mail signatures. Again, Apple asked developers to test the software broadly, listing 22 core components that were in need of specific attention.
Mac OS X 10.5.7, which is code-named "Juno," is believed to be on schedule for a release sometime next month. In barebones Delta form, the update currently weighs in just shy of 440MB. A combo update capable of updating versions of Leopard prior to 10.5.6 weighs about 730MB.
