Note: Unlike previous versions, 3.0.2 is fairly stable and mostly functional on OS X. However, there are still some broken things and it is still the least-tested platform.

Note: We currently do not have prebuilt binaries for any Linux systems. Many distributions now have packages for Aegisub; if yours does not consider requesting or creating one.
