Hot off the electronic press from my software vendor (UltraTax), I have not seen a press release from IRS yet.
"IRS announces change to 2018 Schedule D Tax Worksheet
The IRS has reported to the professional tax software community that they have found that the Schedule D Tax Worksheet for Forms 1040 and 1041 were not properly taxing certain capital gains at the new lower 2018 tax rates, but instead the worksheet was taxing them at their maximum rate of 25% or 28%. The worksheets are used to figure regular tax in certain instances for Filers of Forms 1040, 1040-NR, 1041, and 990-T. The IRS has corrected these worksheets and released newer versions which have been included in UltraTax/1040 version 18.3.7 and UltraTax/1041 version 18.3.6 software updates. Refer to the User Bulletins for these updates for more information on what the IRS has changed and the tax returns affected."

"Per the IRS, only a fraction of returns meeting these specifications [not listed here] will have a different result in tax on the last line of the worksheet to carry to the tax return as the amount of regular tax."
So while the change might impact only a tiny number of taxpayers, unfortunately for those it does affect, there is a ripple effect throughout other forms on the return, such as 2210, PAL calculations, 1116, 2555.
