Looking to have this as a bit of a potential timesave for developers trying to upgrade their Magento 2.3.2 store to 2.3.3
We can maintain this as a community and hopefully ease the pain on others once we've gone through the fire ourselves.
Known Upgrade Issues
- upgrade magento 2.3.2 to 2.3.3 give zendframework/zend-stdlib error
- After Upgrade Magento 2.3.2 to 2.3.3 getting error (addAttributeToFilter not chainable)
- Magento 2.3.2 Upgrade from 2.2.2 (reindexing issue)
One thing that caused me pain was that the third party payment modules broke because in Magento 2.3.2 in the default
Magento_Checkout/js/view/payment/default::placeOrder method, the
isPlaceOrderActionAllowed value wasn't getting checked, but in Magento 2.3.3 the
placeOrder method only runs when that observable is set to true.
That's a great design choice, to make sure the place order action IS ALLOWED, but it does cause issues with modules that didn't have that properly set in 2.3.2 and got away with it. Just something to be aware of...
