The new GS cap is 229. They redid the GS ratings for set pieces as follows:
Before 1.4 - GS 191, After 1.4 - GS 163
Before 1.4 - GS 214, After 1.4 - GS 182
Before 1.4 - GS 240, After 1.4 - GS 204
Before 1.4 - GS 268, After 1.4 - GS 229
This was done to help with balancing out the scores with high end gear (yellow items) and to make weapons and gear more uniform in their ratings. The strength of the items didn't go down, just the rating attached to them. Because of this, max GS dropped to 229 (3 weaps @ 229 & 6 gear @ 229) instead of 255 (3 weaps @ 229 & 6 gear @ 268).
Your still as tough, all that's changed is a number really. Toughness, Electronics etc I've found are most effected and we're far more "squishy" so watch for that and have a look at mods etc to respec when you can.
