Compatibility notes

HeidiSQL runs fine on Windows 8 and 10 (and on Windows 7 with some minor issues)
Running HeidiSQL on newer Wine releases is currently quite unstable. Preferring Wine 4.0 likely solves various issues.
Connecting to TLS 1.2 enabled MS SQL Servers requires an updated OLE DB Driver 18 for SQL Server to be installed.

Latest automatically compiled main executable and installers for HeidiSQL. Just download and overwrite your existing C:Program FilesHeidiSQLheidisql.exe. Be aware that these builds are not official releases and therefore probably have more bugs, possibly serious ones.
