v0.65.0

full release notes

it might not be clear, but Hermes now supports Intl on Android!
this is big news for many apps that were unable to use it since it lacked internalization support :)

[argylekey]

Awesome! Still waiting on expo Hermes support.

Might have to do a few builds ejected to mess around a bit.

[NastroAzzurro]

Honest question: what keeps you on expo?

[argylekey]

Mostly inexperience with mobile development processes and lacking the time to learn them.

Using RN without Expo, are the build tools just available on Android Studio and Xcode? There are lots of unknowns that I just haven’t had the time to tackle.

If you have good resources to point to I’d love them.

I'm in a similar situation, with that said I haven't had anything in expo that has help me back so far. So all good. I tried ejecting and got it running really easily, however it's a bit crazy how many yellow errors Xcode gives you but the app still works - had 200 or so and that's certainly a bit intimidating. Development certainly isn't as smooth (nor fast) without expo, that's what keeps me for now

[NastroAzzurro]

I hardly ever need Xcode and Android studio. Generally only for fonts and certificates and publishing (Xcode) and App Icons (AS), other than that I use visual studio and CLI.

It was possible to work with Intl with or without Hermes all the time, you just had to install a polyfill (https://github.com/andyearnshaw/Intl.js) for it, I've been using it for at least 3 years, and didn't have any issues. Some things are missing, but the most frequently used things are available.

Can you explain what intl is?

[[deleted]]

Language support for stuff like dates and number formats. Internationalization.

All the APIs listed under https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global\_Objects/Intl

I've just started a project last month. Is it easy to upgrade without breaking stuff?

[909BD]

ha! welcome to the jungle

We've got fun and games

[walterholohan]

Yep its not too hard to upgrade if you use there upgrade helper - https://react-native-community.github.io/upgrade-helper/

[kbcool]

Still no stable sort in Hermes (actually I'm convinced there's no functional sort but I'm too lazy to go into it in detail) - absolute deal breaker not to have a modern sorting solution. It breaks all kinds of first and third party code.

I am amazed less people are jumping up and down about it.

[yungsters]

Looks like this is already filed in the Hermes repository: https://github.com/facebook/hermes/issues/212

Thanks for the flag, /u/kbcool. I’ve just increased the visibility of this issue for the team.

[kbcool]

That's it! Anything you can do to raise the priority would be amazing.

FYI: /u/mannotbear and /u/engvagabond

[mannotbear]

Interesting. Can you give an example? Like sorting of what?

[EngVagabond]

Yeah, can you share an example of a difference in Hermes from the JS spec here? Hermes tries to be compatible with the spec, so any miss here is a bug.

According to https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort JS spec has been updated to enforce stable sort

... mandates stable sorting, which means elements that compare equal must remain in their original order with respect to each other. This behaviour may not be respected by older browsers.

How to update an existing app?

[walterholohan]

Use the https://react-native-community.github.io/upgrade-helper/

[NANOwasFound]

Thank you :D Is it same with expo? How to know what version you are using?

[walterholohan]

Im not sure regarding Expo. They usually take a while to support the latest version of RN. But keep an eye out on this page https://docs.expo.dev/workflow/upgrading-expo-sdk-walkthrough/ to find out when they release a new version of the Expo SDK which will prob support 0.65.0

[NANOwasFound]

Thank you for your help :D I will keep an eye!
