Blockstream launches new version of Simplicity to simplify contract development

According to the official blog, Blockstream announced a new version developed by Simplicity: a new developer preview with Jets. Jets can be considered as prefabricated building blocks that can be combined together to build complex Simplicity programs without having to build everything from scratch, thereby speeding up the process of developing smart contracts based on Simplicity while reducing their resource costs. This release also introduces Simplicity support for Bitcoin and Elements test branches.
