This minor update contains more iOS 6 bugfixes, including email composing and the Search sheet on iPad.
The 4.2.5 update’s dyslexia-optimized font addition prompted an influx of positive feedback, and a few people told me about another great font, FS Me. FS Me was designed with and endorsed by Mencap to aid legibility for those with learning disabilities, and it’s now available in Instapaper 4.2.6.
But everyone, not just those with learning disabilities, should give it a try. It’s that good.
