Weights are the same. 5.4 has a lot of small bug fixes and performance enhancement and some added stability things.
And some new features I am planning to announce soon.

Since I am responsible, my extremely biased view is that 5.4 is better.

Hi all,

I updated refmac5.3 to refmac5.4 and found out that the reported RMSDs are quite different from these two versions even the refining protocols are the same.

refmac5.3
rmsBOND rmsANGLE rmsCHIRAL
0.006 0.694 0.046

refmac5.4
rmsBOND rmsANGLE rmsCHIRAL
0.015 1.150 0.004

The R and Rfree are very similar from these two versions of refmac5.  Does refmac5.4 have different geometry weights from refmac5.3?  Which one is more reasonable?

Thanks.

Jianghai
