In the most recent update to the Sage Advice article, Green-Flame Blade and Booming Blade have received errata to their range and spell text, being altered from
Range: 5 feet
Range: Self (5 foot radius)
Furthermore, the text of GFB and BB have been altered from
As part of the action used to cast this spell, you must make a melee attack with a weapon against one creature within the spell’s range, otherwise the spell fails.
to the phrase
You brandish the weapon used in the spell’s casting and make a melee attack with it against one creature within 5 feet of you.
How do these changes alter the way that these spells are used, and how they interact with features or feats, such as Spell Snipers effect of doubling a spells range.
