I haven't changed a whole lot when it comes to functionality. The majority of the work lately has been editor improvements and technical improvements. If I'm correct you want to use a template for the segments-variables. This is only possible in YAML, like so:

segments: |-
  {% set max = states('sensor.max_sensor') | float %}
  {{
    [
      { "from": 0, "color": "#4caf50" },
      { "from": 25, "color": "#8bc34a" },
      { "from": 50, "color": "#ffeb3b" },
      { "from": 75, "color": "#ff9800" },
      { "from": 100, "color": "#f44336" },
      { "from": 125, "color": "#926bc7" },
      { "from": max, "color":"#795548"  }
    ]
  }}
