What is the latest STM32F103RBT6 MCU revision available?

Hi everyone,

I recently found myself having spent a lot of time working to get I2C to work on the STM32F103RBT6 (the problem: I2C begins life in the BUSY state).

This is apparently due to an ADC noise problem, as described in this errata (p. 26):

https://www.st.com/content/ccc/resource/technical/document/errata_sheet/7d/02/75/64/17/fc/4d/fd/CD00190234.pdf/files/CD00190234.pdf/jcr:content/translations/en.CD00190234.pdf#page26

I observed that my Nucleo64 MCU is the "x" revision, which falls under the errata. I am curious: Does ST happen to manufacture a newer revision, which fixes these problems?
