Latest iLevel versions table:


Here are some highlights:

4. Digital Key 1.0 to 1.5 details

1、由于官方在本月初曾发文通告：基于Carkey数字钥匙1.5将在9月推出，之前基于安卓手机的数字钥 匙1.0将被淘汰，那么在此之前激活的数字钥匙届时将无法续费；而能够使用数字钥匙1.5的车辆集成等级必 须是出厂等级为07/2020.XX的车辆，所以，当我升级到07/2020.25后，我的三星手机即不能再作为数字钥匙使用。

在此援此一官方的通告内容：

-从2020年7月开始，互联驾驶商店将架数字钥匙1.0产品，无法续约服务。 您也可以在7月1日前续约您的数字钥匙服务产品。

-出厂集成等级于20-07-5xx，则车辆支持数字钥匙1.0，只支持安卓手机，使用期限为互联驾驶合同开通后的一年内； （如用户有需求使用苹果手机，未来可通过升级车辆软件，刷新BDC模块来支持数字钥匙1.5。苹果手机用户 数字钥匙具体支持时间方法细节待定。）

- 出厂集成等级大于等于20-07-5xx， 则车辆支持数字钥匙1.5，只支持苹果手机，无法支持安卓手机用户。

Translate:
1. Since BMW announced at the beginning of this month: Carkey digital key 1.5 will be launched in September, the previous digital key 1.0 based on Android phones will be eliminated, and The digital key activated before this time can not be renewed; the vehicle integration level that can use the digital key 1.5 must be a vehicle with a factory iLevel of 07/2020.XX, so when I upgrade to 07/2020.25, my Samsung mobile phone can no longer be used as a digital key.

Here is the official announcement:

-From July 2020 onwards, the ConnectedDrive Store will delist digital key 1.0 products and existing service can no longer be renewed. You can still renew your 1.0 digital key service product before July 1.

-If out-of-factory iLevel is older than 20-07-5xx , the vehicle supports digital key 1.0, which only supports Android phones, and the period of use is within one year after the opening of the connected driving contract; (If the user needs to use an Apple phone, the vehicle can be upgraded in the future Software, refresh the BDC module to support digital key 1.5. The specific support time and details of digital keys for Apple mobile phone users to be determined.)

-If out-of-factory iLevel is greater than or equal to 20-07-5xx, the vehicle supports digital key 1.5, which only supports Apple mobile phones, and it does not support Android phone users.

So it seems that Digital Key 1.0 is gonna be eliminated in preference to iOS CarKey.
From what I read is that Digital Key 1.5 needs iLevel update at the dealer.
RSU will bring some new features but not all. This collaborates Jay's comment in another thread that Android Auto will only be available at dealer update.

5. Given the complexity of this major version, OP says there will be incremental .xx updates coming out this month.

6. Numerous small UI changes in iDrive7
