Note of upgrade

2. The pixel code bound by the FBE1.0 version will still take effect and will not affect the current normal reporting.
3. Facebook Data Reporting (Enhanced) Plugin. After FBE is upgraded to version 2.0, it supports the use of the Facebook Data Reporting (Enhanced) Plugin. You can set up data reporting from the server through the Facebook Conversion API to reduce data omissions.
