Engineering Weekly Update - 2021-12-20
- nearmaxOP 2
Brief Summary
- We released nearcore v1.23.0 on Mainnet, but then found out that it made validator kick-out too aggressive. Users and developers are unaffected. We missed this issue while testing on Testnet, because we miss-attributed kicked out validators to a different thing. The hotfix will be released to Testnet this week and to Mainnet the next week;
- If you have any feedback on how DevConsole should look like reach out to @josh.quintal and @tiffanygyj see contact info;
- Check out slides from the Developer Console talk at Ledger Op3n;
- JS SDK now passes all host function tests!
- @jakmeier Joined the Contract Runtime team!
