Version	2.12.0

Summary

The new "listing" mode for SQL statements dumping removes semicolons at the end of the statements and adds an asterisk prefix to each line.

https://github.com/doctrine/orm/pull/9019/files#diff-7579891fde50fb7e38d285004486c0210492efdbdc00815a978e053ff3cb0017R93

This new type of output significantly complicates the possibility of copying SQL statements.

Previous behavior

The following SQL statements will be executed:

CREATE TABLE authorized_identity (id UUID NOT NULL, identity_id UUID NOT NULL, PRIMARY KEY(id));

Current behavior

The following SQL statements will be executed:

* CREATE TABLE authorized_identity (id UUID NOT NULL, identity_id UUID NOT NULL, PRIMARY KEY(id))
