Icecast - May 2022 - ezstream problem

Hello. New here.

I am almost finished an ezstream configuration to work for my
needs (streaming my mp3 collection to icecast server) but the whole
thing seems need some tweak.

I spent some time to find and realize how to configure ezstream
correctly, and end up with next config:

<?xml version="1.0" encoding="UTF-8"?>
<ezstream>

  <servers>
    <server>
      <hostname>127.0.0.1</hostname>
      <password>hackme</password>
      <port>7000</port>
    </server>
  </servers>

  <streams>
    <stream>
      <intake>playlist</intake>
      <encoder>ogg</encoder>
      <mountpoint>/alex</mountpoint>
      <format>Ogg</format>
    </stream>
  </streams>

  <intakes>
    <intake>
      <name>playlist</name>
      <filename>test.m3u</filename>
      <shuffle>1</shuffle>
    </intake>
  </intakes>

  <encoders>
    <encoder>
      <format>Ogg</format>
      <name>ogg</name>
      <program>oggenc -q 1.5 -t @M@ -</program>
    </encoder>
  </encoders>

  <decoders>
    <decoder>
      <file_ext>.mp3</file_ext>
      <program>ffmpeg -i ~/Music/@T@ -f flac -</program>
    </decoder>

  </decoders>
</ezstream>

but it seems, when the track changed, ezstream do not send a 'change
track' information.

Anyone could help ? files metadata is broadcasted, but I expect to
have a 'change' event too.
