Version 4.3.1 is a small maintenance update to fix issues reported since 4.3.0.
**IMPORTANT UPGRADE NOTICE** Please note that not all third party applications and themes are yet compatible with Invision Community 4.3. If you utilize third party resources, including custom themes, please ensure they have been declared compatible by their respective authors or your site may be non-functional after upgrade. There is a new compatibility field on all marketplace resource listings. If this field is missing or does not specifically list 4.3, it is likely not yet compatible.
Not sure if I should be linking to a mediafire upload or if linking directly to the source is okay, so I'll just try the latter. Apologies if this is an issue!
