• 🛑 The Alloy Bootstrap has been removed see #4795
• 🛑 Upgrading from Alloy Bootstrap to Chrome bootstrap appears to ignore cookies from the previous version as the encryption keys are likely different. See #4835 for possible workaround
• CEF now supports the Chromium process singleton, this brings with it changes to how CachePath/RootCachePath are accessed from multiple processes. See #4668 for more details
• ⚠️ Microsoft Visual C++ 2019 Redistributable is required. A minimum of VC++ 2019 is required, higher versions are backwards compatible. For those upgrading from a previous version which only required VC++ 2015 minimum see #3636 for some guidance.
