[Due for payment 2025-06-02] [Due for payment 2025-05-30] [Due for payment 2025-05-28] Upgrade React Native to 0.79

[mountiny]

Upgrade React Native (RN) to the Latest Version for Enhanced Performance and Compatibility

Background:

Over time, our codebase has grown to include numerous custom patches, and the open-source ecosystem around React Native continues to evolve with frequent updates, performance improvements, and new features. Third-party libraries often adapt quickly to these changes.

Problem:

Using an outdated React Native version complicates patch management, restricts compatibility with modern libraries, and negatively impacts app performance and stability.

Solution:

• Upgrade React Native to latest version and update dependencies
• Audit and remove unnecessary patches
• Conduct thorough testing for stability.

Hi, I'm going to work on this 🤝

[war-in]

Hi, I prepared two drafts (OD, ND). Currently, we need to wait for some libs (like expo and react-native-airship) to support RN 0.78.
I'm going to monitor those libraries and start working on the bump again once they're ready 🫡

[mountiny]

Thanks! Lets focus on the 77 to be brought over the finish line

[mountiny]

pushing the 0.77 ahead

[mountiny]

0.77 merged and in staging now

[mountiny]

Draft PRs are starting, but I would post a P/S still

[mountiny]

Working through it, Marcin is ooo

[roryabraham]

I can start helping to shepherd this in the hours when @mountiny's offline

[mountiny]

Would love if you could ❤

There should be no issues with them because QA team has already performed tests on the RN bump PR but @shubham1206agra, please check them 🙏

@roryabraham @mountiny All reviews are done. Please merge them all

[mountiny]

Thanks! @roryabraham most of them are ready for you, some need to sync up with main I think

[roryabraham]

I only skipped over #62577 because of your comment on QA steps @mountiny

[roryabraham]

All the PR's in @war-in's last comment have been merged. Next up, I think we need to redo the react-native-live-markdown PR
