Changed Part Number Database

[Eric Albrecht]

I've recently obtained a new computer and therefore reinstalled all my LDraw programs and library from scratch. It is a good thing to clean house now and then. However, I've run into a serious problem caused by progress. I'm very happy to see that so many unofficial parts have finally been moved to official in the many recent library updates. However, many parts have changed part numbers over the course of many updates. I have hundreds and hundreds of LDraw models archived on my computer, and I find that a great many of them are now broken. I don't mind updating them, the problem is that there is no easy way to find out what happened to an old part. When an old part doesn't load, it doesn't show up in the parts tracker and it doesn't show up in the official library either. I am left scouring the Internet trying to find out what 30039.dat was (for example) so that I can replace it with the current part. Is there any kind of database which tracks old part nnumbers when they change? This would be really useful. I've got my own table now with about 30 parts in it.
