Yes, tzdb release 2021e was published yesterday, and you can now get a copy from <https://www.iana.org/time-zones>. Although there is no official authority for tzdb in the legal sense (<https://data.iana.org/time-zones/tz-link.html#changes> says "The tz code and data are by no means authoritative"), 2021e is published and I expect that downstream redistributors like Apple and Google will pick it up in due course. Unfortunately this distribution process takes time. I expect that most cell phones and other computing devices in Palestine will not be updated before winter time begins next week, so they will display the incorrect time for a day or more. To avoid similar problems in the future, it would be helpful if the Palestinian government could give sufficient notice of when daylight-saving changes will occur. <https://data.iana.org/time-zones/tz-link.html#changes> recommends a year's notice.
