There were no release notes for the last server maintenance, but this weekend I noticed some new things that surprised me.
1. Kobali phenotype options are now available at the tailor; Kobali are included in Delta Rising, but I did not expect to see components released without comment.
2. The cost of DOffs at the dilithium vendor at bases has gone up ~30% (now 800 dil for an uncommon, vs ~550).
I didn't go on a search for other changes, but I was disappointed to get no notice; therein lies the question, "did I miss the announcement somewhere else?". If not, then the "stealth updates" continue...
