We could add a blog repo to this organisation, and clone https://github.com/rust-community/rust-lang-blog-boilerplate

@HalidOdat i wonder if we can get better before / after images now there's been more work done

Made a simple bash script for generating the profiles with specified branches/commits, I can go as back as the time mesureme was introduced to boa and as forward as master HEAD. Is there a specific range you want me to profile?

[HalidOdat]

Did a before and after from commit 32b0741c to master HEAD
32b0741c: (when #317 was merged, 58ms)

and master HEAD (15ms):

[HalidOdat]

Did a benchmark of Realm creation and its a ~70% improvement :)

[HalidOdat]

Maybe we should have a section for Internal improvements rather than everything being a feature, for example #465 does not add a new feature for the user to use, it is only an optimization.

What do you think? @jasonwilliams @Razican

[pedropaulosuzuki]

Could #525 be packed into v0.9? Would be pretty nice to have feature-complete Math object in the new release, since we got bigint in the last v0.8 release, and from the PR it seems to be ready/close to ready.

I think this makes a lot of sense, so that users can find what's new with ease and also see what's new on the internals of Boa, and what has been done to make it so much faster on each update.

That's amazing!!

Sure! I don't see a reason why it shouldn't go in v0.9 :)

[jasonwilliams]

I’m hoping to set up a blog so we can move a lot of content over to there, then I can update the change log

[jasonwilliams]

we're now up and running on https://boa-dev.github.io so we just need to write up the content

[jasonwilliams]

internel improvements have been added
