8.0.0 (2026-08-17)

⚠ BREAKING CHANGES

• supabase: migrate from Newtonsoft.Json to System.Text.Json (#360)
• realtime: migrate from Newtonsoft.Json to System.Text.Json
• postgrest: migrate from Newtonsoft.Json to System.Text.Json
• storage: migrate from Newtonsoft.Json to System.Text.Json (#358)
• gotrue: migrate from Newtonsoft.Json to System.Text.Json (#357)
• functions: migrate from Newtonsoft.Json to System.Text.Json (#356)
• packages now target netstandard2.1 instead of netstandard2.0. .NET Framework consumers (netstandard2.0 is its ceiling) and pre-netstandard2.1 runtimes (Mono <6.4, older Xamarin/Unity) can no longer reference these packages and must move to a netstandard2.1-capable target (.NET Core 3.0+/.NET 5+).
• postgrest: IPostgrestTable.Delete(QueryOptions?, CancellationToken) and its Table implementation now return Task instead of Task. await table.Delete() is unaffected; code that assigns the result to Task or captures the method group must be recompiled/adjusted.
