Esky patching procedure - esky

Question

I'm trying to auto update using Esky differential patches, but I haven't been able to get the app to update using only those differential patches. It seems like a full version is always needed for a correct update.
So, if I have version 0.1 and patches plus full file versions up to 0.3 in the updates server, the client app will fetch both the patches AND the full latest version file:
updatesServer/
App-0.1.win32.zip (client version running)
App-0.2.win32.zip (this isn't fetched)
App-0.2.win32.from-0.1.patch (this is fetched first)
App-0.3.win32.zip (this is fetched third)
App-0.3.win32.from-0.2.patch (this is fetched second)
Also, if the latest version weren't to be available (App-0.3.win32.zip in this case), the update would fail.
The behavior I would expect is for Esky to get the patch file and update while ignoring the other full file version available so the update is blazing fast. Is there a way to achieve this?
Environment info: the freezer I'm using is cx_freeze and my Python version is 3.4.
Update-routine code:
from esky import *
from esky.util import appexe_from_executable
def restart_this_app():
appexe = appexe_from_executable(sys.executable)
os.execv(appexe,[appexe] + sys.argv[1:])
if hasattr(sys, "frozen"):
app = esky.Esky(sys.executable, UPDATES_URL)
print("You are running version "+app.active_version)
print("Looking for updates...")
if app.find_update() is None:
print("No updates have been found.")
else:
print("Updates available. Updating...")
try:
app.auto_update()
except Exception as e:
print("Error while updating:", e)
else:
print("Update complete.")
print("Restarting app...")
time.sleep(3)
restart_this_app()
BTW, this is my first StackOverflow question ever. Thank you for taking a look at it ;)
