LPC2138/2148 bootloader version differences

Anyone know of a writeup/errata on the code differences/enhancements added between version 2.12 and 2.13?  I think we had a bad batch of chips where reading from code memory gave intermittent errors on LPC2148 chips version 2.12.  We changed to a LPC2138 since we didn't need the USB and the problem completely went away.  We changed one of the failing LPC2148 chips to a new batch of 2138 chips and the problem went away as well.  Not sure that the bootloader changes would have anything to do with chip read errors, but it would be nice to see what was different.  Could have been just a bad batch.
