v1.11.0 - Taco Tuesday

As Always

A very special thank you to everyone who submits issues and contributes code. In this release, @rferraton and @ClaudioESSilva got some pretty cool new stuff in. The full change log is below, but the Query Store integration is quickly becoming the star of the show in a lot of ways. It's almost like a self-contained monitoring tool at this point.

There's a web version of the plan analysis portion of the app too. This is useful for people who want to give things a test drive, or who can't download an executable. The plan analysis is all client-side. You completely control whether and when the plan gets uploaded for sharing, and how long it remains available for. I have no interest in your XML unless you're paying me.

v1.10.0 - Pants Are Important

v1.10.0

The ongoing work to make this simpler to add rules/information about things in plans will eventually allow users to extend things to deal gracefully with local issues. Right now I'm not sure how it will go. For informational bits like wait stats, it's very easy. For arbitrarily complex rules, it's a bit harder to jam those into a json config file that can be interpreted correctly and consistently.

Anyway, as always, thank you to my valuable contributors of code, and Joe Obbish for the high quality feedback.

If you have any questions, comments, concerns, ideas, or you'd like to support this project, head over here.

New features

• Connect with ApplicationIntent=ReadOnly — the connection dialog now lets you opt into read-only routing, useful for AG secondary replicas. (#302)
• Wait stats config is now the single source of truth — wait categories, weights, and benefit scoring are driven from Resources/WaitStats.json instead of being scattered across services. (#215 part 1 in #296, part 2 in #300)

UX changes

• Default grid grouping is now Query Hash instead of None, and the first row no longer auto-expands when results load. Faster to scan plans by hash without a click. (#305)
• Connection dialog polish — tighter test-status row spacing and follow-up cleanup. (#299, #303)

Fixes

• Rule 38 (MAXDOP advice) now respects an explicit MAXDOP 2 hint — the rule no longer fires when the query is already pinned to MAXDOP 2. (#304)
• MFA auth error text is readable — the connection-test status text now wraps/displays correctly when the server returns an MFA-related error. Thanks @ClaudioESSilva! (#298, fixes #297)

Internal / chore

• Removed unused ExpandRowRecursive after the GroupBy default change. (#306)
• Added .gitattributes and ran a one-time line-ending normalization (LF for source/config; CRLF for .ps1/.psm1/.psd1/.cmd/.bat). Eliminates phantom CRLF diffs on Windows. (#307)
• Bumped PlanViewer.App version 1.9.0 → 1.10.0. (#308)
