The church has made statements that the corrections made are an attempt to bring the text as close as possible to what Joseph Smith actually translated. Missing phrases added back in is understandable.
However,I am a bit disturbed by changing white to pure. I can understand why the church leadership found it necessary. I know the church is led by men, and not by angels. I debated awhile back in my scripture study about using the paragraph markings and unifying the verses back together. Based on these comments, I think I will, especially because I have already read them in their current form, and perhaps it will give me new insights.
