geom_text vs theme(element_text) in ggplot2 v2: Unknown parameters: face

This example works fine:

library(ggplot2)
ggplot(diamonds, aes(clarity, fill=cut)) + geom_bar() +
      theme(panel.border = element_blank(), panel.grid.major = element_blank(), 
            panel.grid.minor = element_blank(), axis.line = element_line(colour = "black"),
            legend.title = element_text(size=12, face="bold"),
            axis.title.x=element_text(face="bold", vjust=0.1),
            axis.title.y=element_text(face="bold", vjust=0.4))

In my own plots, the "face" parameter is problematic:

ggplot()+
  #geom_point(data=sitescores2, aes(x=rda1, y=rda2, color=Dates), shape=17)+
  geom_segment(data=biplotscores2, aes(x=0, y=0, xend=rda1, yend=rda2), arrow=arrow(length=unit(0.2,"cm")), alpha=0.75, color="black") +
  geom_text(data=biplotscores2, aes(x=1.1*rda1, y=1.1*rda2,label=rownames(biplotscores2)), size=3, color="black", face="bold")+
  #xlab("rda1   (45.7% explained variance)")+
  #ylab("rda2   (19.3% explained variance)")+
  #annotate ("text", x = 0.5, y = -0.75, label = "Constrained Inertia 20.3%") +
  theme_bw()+
  theme(panel.border = element_blank(), panel.grid.major = element_blank(), 
        panel.grid.minor = element_blank(), axis.line = element_line(colour = "black"),
        legend.title = element_text(size=12, face="bold"),
        axis.title.x=element_text(face="bold", vjust=0.1),
        axis.title.y=element_text(face="bold", vjust=0.4)) +
  guides(color = guide_legend(override.aes = list(size=4)))

Whenever the geom_text() line is not commented out, i am getting

Error: Unknown parameters: face

Do you have any idea, what has changed in the newest version of ggplot2?

I believe the aesthetic in geom_text is actually called fontface, not face, even though in element_text it is called just face. I believe this is simply a naming inconsistency.

According to this Github commit, the geom_text aesthetic has been called fontface for a long time now.
