Orb version: 5.1.1

        - run:
          name: Get changelog
          command: |
            echo "circle test" > releasenotes.txt
            echo "circle test 2" >> releasenotes.txt
            echo "circle test 3" >> releasenotes.txt

            rnotes="$(cat releasenotes.txt | awk '{printf "%s\\n", $0}')"
            echo "export M_CHANGELOG='$rnotes'" >> $BASH_ENV
      - slack/notify:
          event: pass
          channel: "#builds-android"
          custom: |
            {
              "blocks": [ 
                {
                  "type": "section",
                  "text": {
                    "type": "mrkdwn",
                    "text": "$M_CHANGELOG"
                  }
                }
              ]
            }

actual result message in slack writen as

circle test\ncircle test 2\ncircle test 3\n

expected result message in stack writen as

circle test
circle test 2
circle test 3

found an issue. Orb (or slack API inside) ignores new line if string is not formated as UTF8. It seams releasenotes.txt is created at UTF16 formated. When i change its encoding to UTF 8 than it works well

      - run:
          name: Get changelog
          command: |
            RELEASE_NOTES=$(cat releasenotes.txt)
            echo "export M_CHANGELOG='$RELEASE_NOTES'" >> "$BASH_ENV"

      - slack/notify:
          event: pass
          channel: $SLACK_DEFAULT_CHANEL
          custom: |
            {
              "blocks": [
                {

                {
                  "type": "section",
                  "text": {
                    "type": "mrkdwn",
                    "text": "$M_CHANGELOG"
                  }
                }
              ]
            }

Slack doesn't take the environment variables, that's done by the orb. This is interesting though, because the orb basically creates a new string with the expanded values, so the original encoding shouldn't be problematic. I'll be taking a look at this, and try to improve the behavior, but as there is many other ways to have the desired result, is not the highest priority.
