In the next development release of GJS (1.81.1), we are going to bump the Meson dependency from 0.58 to 0.62. 0.62 was released March 2022, so I don’t expect problems, but let me know if there are any.
As a heads up, we will also likely depend on SpiderMonkey 128 this cycle, but that’s not certain yet. I will make a separate post with more information when that happens.
