The last 24 hours has been the first time that Synchronet has run (mind you, just experimentally on Vertrauen) with a new JavaScript library (libmozjs-128) in many years!

This is a huge change to Synchronet and unfortunately, isn't 100% backward compatible. A number of non-standard language features that were allowed in the old JavaScript engine (SpiderMonkey v1.8.5) are now not allowed. :-(

I'm actively updating the JavaScript files that are included stock with Synchronet to make sure they'll be both backward and forward compatible, but I don't have control over all the 3rd party JavaScript files to test or update as needed.

Here's a write-up about those incompatibilites and the things that Synchronet JS developers like you can do to insure your scripts are compatible with future and current (and even recent past) Synchronet releases:
https://gitlab.synchro.net/main/sbbs/-/blob/next-js/docs/sm185_to_sm128_incompatibilities.md

It's still too early for others to run this development branch for their BBS, but I just wanted to give you all the news and a head's up that *some* existing JavaScript files won't be immediately compatible with the next big Synchronet version bump (I'm calling v3.30).

On the bright side, you'll get all the ECMAScript 2024 language features (https://en.wikipedia.org/wiki/ECMAScript_version_history) and performance and relability features included a modern JavaScript engine from Mozilla!
Get excited!

Re: Synchronet v3.30 development started (*new* JavaScript library!)

Howdy,

The last 24 hours has been the first time that Synchronet has run (mind you, just experimentally on Vertrauen) with a new JavaScript library (libmozjs-128) in many years!

Yay :)

It's still too early for others to run this development branch for their BBS, but I just wanted to give you all the news and a head's up that *some* existing JavaScript files won't be immediately compatible with the next big Synchronet version bump (I'm calling v3.30).

Is it in a branch (I just went and had a look - "next-js")? Can we play with it and perhaps help identify the incompatibilities, or do we just have to patient and wait?

Hoping as part of the SBBS build we can use an OS supplied library to save on build time?

I think that will be an overall good update.

If you really want to build and run it, yes, the branch is 'next-js', but there are plenty of known issues (e.g. no Windows build support yet) and many of the stock scripts still fail with errors.

Hoping as part of the SBBS build we can use an OS supplied library to save on build time?

Yes, the plan is to use the system's libmozjs-dev-128 package if/while there is one. For Windows, I'll continue to vendor the built binaries and headers in the repo for Windows (only).

And speaking of Windows, this does mean the end of Windows 7 support for new Synchronet versions: Spidermonkey 128 only supports Windows 8 and later. But gladly, Spidermonkey 128 still supports 32-bit Windows editions (of 8 and 10).
