upgrading stdperph libs from 1.0 to 1.3 slowdowns and no more uart

Is there a document that says all the steps in changing from 1.0 to 1.3 ?

I downloaded 1.3 and put it where I had my old library files.
Then I defined STM32F40_41xxx (i'm using stm32f407 disovery)
Changed out my startup for the new one (with similar name _41xxx)

It compiles and runs, but its really slow. The leds blink on startup and I could not even count them, now I can clearly count the times they blink. Also Usart communication is not working. Swapping the folders back out for the v1.0 libs everything worked again.

There were some changes to do with the PLL in system_stm32f4xx.c that changed from version to version. Should I be changing something to set the clock to 168mhz ?

Thanks ! This is to try and fix another issue (dma TE issue) and I've expended all of my time on that.
