SpringBoot Backslash is escaped in yaml when preceding ${prop} since SB 3.4.0

considering following application.yaml plic: ploc myValue: XXX\${plic}

and a field annotated with : @Value("${myvalue}")

Interpreted value is XXX\ploc in 3.3.x and before Interpreted value is XXXploc since 3.4.0

Is this a known issue, or documented behaviour change ?

Thanks in advance Ludovic
