Logic was updated to 9.0.2 last night. The Software Update has probably already notified you. If you were fast, you might have noticed the incorrect link to the release notes. I've posted the correct link below.
This update improves overall stability and provides numerous fixes and enhancements.
Issues addressed include:
- Flex Markers can align & snap to MIDI notes
- Performing a punch-in recording with Replace Mode now behaves correctly
- The I/O plug-in adds an option for latency measurement
- TDM plug-ins now behave as expected. (Only affects users with Pro Tools HD audio hardware.)
- The update is recommended for all users of Logic Pro 9.
