2026-03-30 - Version 2026.3.30

Bug Fixes

  • Fixed drawing path logging to Loki on close events — was logging the active document's path instead of the closing document's path when multiple drawings were open

Improvements

  • Drawing path now included in all close event logs for better diagnostics

2026-03-26 - Version 2026.3.26

Improvements

  • Error handling at managed/unmanaged boundary crossings now catches exceptions, logs to Loki, and shows a friendly error dialog instead of crashing AutoCAD
  • Error dialogs now show a clean user message instead of raw stack traces
  • License validation errors now logged to Loki instead of Console

2026-03-20 - Version 2026.3.20

New Features

  • Default CV Loss: Toolbar input (default 5 psi) applies fallback pressure loss to control valves with no loss configured in EPANET model
  • POC Name Property: Point of Connection name now displayed in mainline analysis results and Excel reports

Bug Fixes

  • RequiredPressure Update: Find Critical now updates RequiredPressure from critical station design pressure during iteration
  • CZA Results Persistence: Switching away and back to the same drawing no longer clears analysis results
  • UI Text: Uncalculated summary now says "Find Critical Zone" instead of "Find Critical"
  • IsInternalModification Safety: Flag wrapped in try-finally to prevent permanent stuck state on exception
  • Polyline3d Leak: Fixed undisposed Polyline3d in elevation model convex hull fallback

Improvements

  • EPANET temporary files (.inp, .rpt, .log) now written to %TEMP%/Raindrop_EPANET instead of the drawing folder
  • Removed "Pressure Drop" button from toolbar (accessible via entity properties)

2026-03-19 - Version 2026.3.19

New Features

  • Add Layer Commands: New IR_MakeLayer and LS_MakeLayer commands to quickly create layers with the configured irrigation or landscape prefix. Dialog includes prefix dropdown, layer name input, and Make Current checkbox. New layer inherits the current layer's color.

2026-03-18 - Version 2026.3.18

New Features

  • Session Log Toggle: New setting on the App tab to enable/disable local session logging (.md files alongside drawings)

Improvements

  • Settings tabs reordered: Project tab now first, App tab moved to last
  • "General" tab renamed to "Project" for clarity
  • Settings tab navigation uses typed enum instead of fragile integer indices

Bug Fixes

  • Fixed NullReferenceException crash when opening Settings on corrupted or unnamed drawings
  • Fixed session log files being written even when session logging was disabled

2026-03-08 - Version 2026.3.8

New Features

  • Critical Zone Analysis (IR_CZA): New IR_CZA command performs mainline + zone hydraulic analysis in a single run with Excel report output
  • CZA Palette: Interactive palette with Find Critical iteration, zone status coloring, and zoom-to-zone highlighting
  • User Valve Selection: Combined analysis prompts user to select which control valves to analyze instead of auto-detecting
  • Dynamic Pressure Loss Valves: Backflow and master valve pressure losses pulled dynamically from drawing entities
  • Booster Pump Support: Critical path traversal includes pumps, reporting pressure gain in output and Excel report
  • DRCV Bubbler Zone Support: Drip control valves can now build zone networks for bubbler system analysis

Improvements

  • Excel report uses formulas for minor losses, pressure sums, and residual calculations
  • Locked file handling appends (1), (2) suffix when Excel or EPANET files are in use
  • Mainline friction calculation uses EPANET pressure subtraction for accurate looped network results

2026-03-02 - Version 2026.3.2

New Features

  • Date-Based Versioning: Switched from semver (1.5.x) to date-based format (YYYY.M.D)
  • Toolbar Redesign: Action buttons on top row, version/license info on compact second row
  • Update Tooltip: Version number now shows incoming update version when available
  • Grafana Loki Logging: Migrated remote logging from Seq to Grafana Loki

Improvements

  • Custom log server endpoint now configurable in Settings
  • Toolbar spacing tightened for a more compact layout
  • Green check icon shows when client is up to date

2025-12-20 - Version 1.5.113

Bug Fixes

  • Fixed valve, controller, and pump symbols inserted at wrong size when drawing units are inches
  • Added PumpPlotSize minimum to prevent zero-size insertions
  • Fixed copy-paste comments in ControllerFactory

2025-12-15 - Version 1.5.112

Bug Fixes

  • Fixed 'Not a block reference' error when sizing pasted valves (valve paste designator handle)

2025-12-10 - Version 1.5.111

Bug Fixes

  • Fixed sprinkler rotation with non-world UCS and view twist alignment
  • Fixed sprinkler polyline layout when UCS differs from WCS
  • Fixed legend creation breaking with non-world UCS
  • Fixed paint pipe flow callout positioning to prevent hiding behind prompts
  • Fixed drawings always showing as unsaved after save

New Features

  • Added construction warnings to solver results and show on network load

Improvements

  • Optimized FixDrawOrder to use single SelectAll call
  • Legend now creates at origin and transforms once (UCS-safe)
  • Reduced Keygen API request volume by improving cache behavior

2025-11-28 - Version 1.5.110

New Features

  • Mainline Analysis: Pump and source properties are now editable directly in the Mainline Analysis form
