namespace blink {

// The "Blink-side" serialization version, which defines how Blink will behave
// during the serialization process, is in
// SerializedScriptValue::wireFormatVersion. The serialization format has two
// "envelopes": an outer one controlled by Blink and an inner one by V8.
//
// They are formatted as follows:
// [version tag] [Blink version] [version tag] [v8 version] ...
//
// Before version 16, there was only a single envelope and the version number
// for both parts was always equal.
//
// See also V8ScriptValueDeserializer.cpp.
//
// This version number must be incremented whenever any incompatible changes are
// made to how Blink writes data. Purely V8-side changes do not require an
// adjustment to this value.
