2.0.0!

[Alon Zakai]

Hi everyone,

Last week we released Emscripten 2.0.0. That's a big milestone as it's the first version to not support the old fastcomp backend anymore,

https://github.com/emscripten-core/emscripten/issues/11319

You can still use it by using an older version (the last to support fastcomp is 1.40.1), but the new upstream backend is better in every way! And it's been the default version when you install "latest" etc. for quite a while now.

This is also the first version to not support Python 2.*, and only support 3.*

Both of those don't have immediate benefits, but they are letting us do a lot of cleanups and simplifications. See

https://github.com/emscripten-core/emscripten/issues/11860

We've already improved code quality quite a bit in just a week, and there's a lot more to come. These simplifications will speed up development. They will also unblock some things that were tricky to do while we supported two backends, such as some link time improvements and better debugging support - specifically we aim to do less during -O0 links, both for speed and to properly preserve DWARF info (for example, one of the first parts of that is in https://github.com/WebAssembly/binaryen/pull/3044).

Hi,

Sorry for my stupid question but someone can explain me what is the difference about:
https://github.com/emscripten-core/emscripten and https://github.com/emscripten-core/emsdk ?

I normally use the emsdk to compile my C codes to create the WASM and run into web.

Thanks

emscripten is the compiler itself (really a compiler driver) and it has many dependencies such as llvm, nodejs, python, and binaryen.

emsdk is an easy way to install emscripten along with pre-built and tested versions of all its dependencies.

I normally use the emsdk to compile my C codes to create the WASM and run into web.

Thanks

Thanks for reply,
And are there a tutorial how to compile it using hard mode ( emscripten ) and not using the easy mode ( emsdk ) ?

Because if I use a prebuild it mean that it is outdated and all new updates are not available right?

Thanks

Emsdk is the official way to install new versions of emscripten, so you're not losing out on anything by using it :) Installing all the different parts of Emscripten without using emsdk is actually a huge pain and doesn't have any benefits unless you're doing development on Emscripten itself.

I got it,

Thank you

[Sam Clegg]

In addition emsdk support a version called "tot".. which means "tip of tree".  If you do `emsdk install tot` you will get pretty much the latest possible version of emscripten all its dependencies.   This version generally contains versions that are no older than an hour or two.

Thanks, Alon [and all] for this release and other work on emscripten. I got it
to work for https://fc-solve.shlomifish.org/js-fc-solve/text/ eventually.

Congrats to the team on the 2.0 release! And thank you for this awesome tool, don't know what we would do without it :)
