Release v66.5.1

66.5.1 - April 9, 2026

Added

salesforcedx-lwc-language-server

• We added a URL to LWC error messages for easier debugging. (PR #7123)

salesforcedx-vscode-apex

• The Apex Language Server now uses the MetadataRegistryService to determine which folders to scan, skipping folders that cannot contain Apex files to reduce indexing time. (PR #7135)
• We improved detection of orphaned Apex Language Server processes. Detected orphans are now automatically shut down in the background after approximately 30 seconds, rather than prompting the user to terminate them. (PR #7135)

salesforcedx-vscode-apex-testing

• The Test Explorer's default Run button now runs only in-workspace tests. Run All Tests in Org has been moved to a secondary profile in the run dropdown. We also fixed a bug where Test Explorer exclusion filters were not consistently applied when test suites were expanded. (PR #7137)

salesforcedx-vscode-core

• We introduced a new Org Differences view that displays conflicts and diffs between your project and org during deploy, retrieve, and delete operations. When a conflict is detected, you can view the conflicting files, override them, or cancel the operation. (PR #7009)
• We added a new status bar icon that shows the sync state between your project and org at a glance. It turns red when conflicts are present — hover to see which files are affected, and click to deploy local changes, retrieve remote changes, or open the Org Differences view. (PR #7009)
• Conflict detection is now smarter: only components in the current deploy/retrieve/delete set are checked for conflicts, and whitespace-only differences are no longer flagged. (PR #7009)
• We added a new Show Success Notification setting that controls whether a notification toast appears after a successful deploy, retrieve, or delete operation. (PR #7009)

salesforcedx-vscode-expanded

• We added the Salesforce Metadata Visualizer extension to the Salesforce Extension Pack (Expanded). (PR #7129)

salesforcedx-vscode-soql

• The SOQL Builder UI now hides its query builder dropdowns and Run Query button, and shows a warning when no default org is set. (PR #7092)

Fixed

salesforcedx-aura-language-server

• We fixed an issue where the Aura Language Server was producing an error notification when reindexing Aura components. (PR #7133)

salesforcedx-vscode-apex-oas

salesforcedx-vscode-apex-replay-debugger

• When an org lacks access to PackageLicense, we added a fallback to the InstalledSubscriberPackage tooling query. (PR #7155)
• We made some changes under the hood. (PR #7130)

salesforcedx-vscode-apex-testing

salesforcedx-vscode-metadata

• We fixed a bug where debugging a single test method in the Apex Test Explorer incorrectly ran the entire class instead of only the selected method. (PR #7127, ISSUE #7120)
• We fixed a bug where the Apex Test Explorer did not refresh after metadata changes. (PR #7140)
• We added a message to the Apex Testing sidebar reminding users to deploy their Apex tests to the default org if no tests appear. (PR #7152)

salesforcedx-vscode-core

• We made some changes under the hood. (PR #7145, PR #7073, PR #7124)

salesforcedx-vscode-org

salesforcedx-utils-vscode

• We fixed a bug where duplicate Org Management output channels were created. (PR #7144)
• We fixed a bug in Agentforce Vibes IDE where, after re-authorizing via the login popup, the status bar continued to show No Default Org Set, and attempting to set the newly authorized org as the default produced Error: No authorization information found for reauth-vscodeOrg. (PR #7141)

salesforcedx-vscode-services

• We made some changes under the hood. (PR #7138)
• We fixed a bug where creating Typescript LWC components was failing. (PR #7126)
