Check logic:

def compare_version(current_version="0.0.0", current_stage="stable", compared_version="0.0.0", compared_stage="stable"):
  # return -1 if the current version is newer (not released dev)
  # return 0 if the current version is same as newest
  # return 1 if the current version is older
  pass

current_release_version = get_version()
current_release_stage = get_version_property("stage")

if stage == "stable":
  latest_release_info = requests.get("https://api.github.com/repos/iXORTech/RemoteMC-MCDR/releases/latest").json()
  latest_release_tag_name = latest_release_info["tag_name"]
  latest_release_version = latest_release_tag_name
  compare_version(current_version=current_release_version, compared_version=latest_release_version)

else if "dev" in stage or "alpha" in stage or "beta" in stage or "rc" in stage:
  latest_release_info = requests.get("https://api.github.com/repos/iXORTech/RemoteMC-MCDR/tags").json()
  latest_release_tag_name = latest_release_info[0]["name"].split("-")
  latest_release_version = latest_release_tag_name[0]
  latest_release_stage = latest_release_tag_name[1]

  pass
