You can get this EAP build through the Toolbox App, by downloading it from the website, by using a snap package (for Ubuntu), or from right inside GoLand by selecting Automatically check updates for Early Access Program in Preferences / Settings | Appearance & Behavior | System Settings | Updates.
Don’t forget that we regularly release nightly builds based on the latest development code. You can use these nightly builds to get access to the latest features without having to wait for the official EAP announcements. These nightly builds are only available via the Toolbox App, however.
GoLand 2020.1 will now show a notification before you commit if there are replacements with local paths in the go.mode file. This should help avoid situations where these replacements are committed by mistake.
Please note that the Perform Code analysis checkbox has to be turned on in the settings of the Commit dialog first. Click the gear icon and then select this option if needed.
