Version 1.3.5

This micro-release fixes a large number of issues, applies some performance optimizations and resolves some regressions introduced in previous micro-releases. The main regressions that were addressed include rendering of ChatMessage reaction icons, the ability to obtain an OAuth access_token if it is not a valid JWT token, and issues with async callbacks. We are very pleased to welcome new contributors @mitulb, @fazledyn-or, @benbarn313 and @vaniisgh and want to thank them for their contributions. We also want to thank @cdeil for continuing to contribute and the maintainer team including @MarcSkovMadsen, @hoxbro, @maximlt, @ahuang11, @droumis and @philippjfr for their continued efforts.
