v1.5.0 — spacing control, subquery indentation, comment preservation

Major formatting-control update for the rule-based (offline) engine.

New in this release

• Blank lines between statements — set the exact number of blank lines between top-level statements (nested statements inside BEGIN...END are untouched; comments stay attached to their statement)
• Blank lines before / after GO — exact spacing around batch separators; GO 5 counts and trailing comments on the GO line are kept
• Subquery re-indentation — nested subqueries and derived tables are always indented at least one level per nesting depth
• Preserve comments (on by default) — comments are re-inserted next to the code they belong to after formatting; never silently deleted
• Leading or trailing comma placement
• Indent with tabs option
• Max consecutive blank lines and trim trailing whitespace
• Full Custom rule set — every rule used by the Classic and Modern presets is now individually configurable
• Help — new Help page under Tools → Options → Format T-SQL Script, and a "Format T-SQL Script Help" entry in the Tools menu

Install / upgrade

Notes

• Scripts with syntax errors are never modified.
