Ancestry.com has announced they will be making a number of updates during August. These include:

More accurate number of shared segments (beginning early August)

See the length of your longest shared segment (beginning mid August)

Distant DNA matches must share 8.0 cM or higher (beginning late August)

This will be the third time Ancestry has changed their DNA and ethnic algorithms in the last five years. It will be interesting to see what changes these updates will bring.
