[nginx-announce] njs-0.9.1

[Dmitry Volyntsev]

Hello,

I'm glad to announce a new release of NGINX JavaScript module (njs).

This release adds Fetch API support to the QuickJS engine, bringing
it to feature parity with njs. Additionally, the shared dictionary now
includes state file support, allowing its contents to persist across
nginx restarts.
