This maintenance release restores legacy Penn measures, corrects axial normalisations, and improves macOS release packaging.

Analysis fixes

• Restored Metric Step Penn Distance in VGA metric step-depth analysis.
• Restored Metric Mean Penn Distance in VGA metric analysis.
• Restored Penn-distance attributes when converting legacy graph files.
• Corrected axial Integration [P-value] to use the pyramid P-value normalisation instead of duplicating the D-value/HH calculation.
• Corrected RA [Penn] to use the actual maximum shortest-path depth.
• Hardened the Penn palm-tree normalisation for invalid and out-of-range inputs.
• Preserved unavailable legacy Penn values and prevented negative detour distances.
• Added regression tests covering the restored measures and corrected formulas.

macOS and release packaging

• Re-signed macOS application bundles after deployment to prevent macOS reporting them as damaged.
• Added checks for invalid signatures and remaining Homebrew library links.
• Improved release reruns so existing release notes are preserved while assets are replaced.

Compatibility note

@varoudis :
Be careful! Axial Integration [P-value] and some RA [Penn] results may differ from earlier releases.
Previous versions calculated P-value integration using the D-value formula and could use an incorrect maximum depth for Penn normalisation.

Downloads

macOS ships as two builds. The Apple Silicon binary will not run on an Intel Mac,
so pick the one matching your machine. The depthmapXcli_* files are the
command-line tool.

Opening depthmapX on macOS

depthmapX is not signed with an Apple Developer ID, so macOS blocks it the first
time. The app is unmodified — it simply has no paid Apple signature.

1. Double-click depthmapX. macOS refuses and offers only Done or Move to
   Bin — click Done.
2. Open System Settings → Privacy & Security and scroll to Security. You
   will see "depthmapX" was blocked to protect your Mac. Click Open Anyway.
3. Confirm Open Anyway and authenticate if prompted.

You only need to do this once. On macOS 14 and earlier, right-clicking the app
and choosing Open works instead.

If you prefer the terminal:

xattr -dr com.apple.quarantine /Applications/depthmapX.app

Full Changelog: v0.9.0...v0.9.1

The first release since 0.8.0 (November 2020). It collects the 2020–21 work that
was never released, fixes two bugs that produced wrong results or crashes, and
ships native binaries for four platforms.

Have fun all and test if you can as there are a number of old changes/fixes! ( @varoudis )

If you use subtraction in SalaScript on macOS or Linux, see the first item —
affected analyses should be re-run.

Fixed

• SalaScript subtraction returned the negated result on macOS and Linux:
  5 - 3 gave -2. The operands were evaluated in an order C++ leaves
  unspecified, and both clang and gcc picked the one that flips the sign. Every
  macOS and Linux build to date is affected.
• Converting a map from a zero-width or zero-height region divided by zero
  and attempted a ~51 GB allocation, crashing or exhausting memory depending on
  platform. Such regions are now rejected with a clear message.
• Map conversion stored indices instead of refs, corrupting the result.
• Line height is now taken as an absolute difference.
• Clicking an invalid pixel no longer crashes when its shapes are requested.
• The displayed data map can no longer go negative.
• The Windows build works with current MSVC again; a custom log2 collided
  with the compiler intrinsic and is now pafLog2. The MinGW build is also
  fixed.

Added

• Binaries for four platforms, GUI and command line, built and tested
  automatically for every release.
• Line transparency is honoured where it has been provided.
• Shapegraph links and unlinks can be exported.
• A modular CMake build, with generalised build directories.
• Continuous integration on Linux, macOS and Windows. The previous service
  had been shut down for years, so nothing had been checked automatically since
  2020.

Changed

• Entropy values may differ in the last bit. As a side effect of the
  pafLog2 rename, entropy now uses depthmapX's own base-2 logarithm
  everywhere; macOS and Linux previously used the compiler's built-in log2
  silently. About 27% of inputs differ, by at most one double-precision epsilon
  (2.2e-16). Conclusions are unaffected, but final digits can move.
• The isovist angle dialog no longer appears when a full isovist is requested,
  and data maps are hidden while isovists are being created.
• Agent steps and field of view accept whole numbers only.

Thanks to @pklampros and @blsemo for the 2020–21 work included here.

General:

• Allow for pushing values from shapemaps (axial maps, segment maps) to VGA
• Fix VGA map connections export
• Make drawing to segment conversion faster
• Test and fix shape removal for axial and data maps
• Allow pushing the Ref or Key value to another layer
• Fix MIF/MID import (allow for empty columns, PR #369)
• Fix diagonal line handling on VGA map fill (PR #326, thanks Piotr Piastucki!)
• Change C++ standard to 17

Graphical User Interface (GUI):

• Highlight shapes and pixels on hover (can be disabled in the settings)
• Allow inserting any number in the table (PR #356)
• Fix a case where the app would crash with multiple unlinking in VGA (PR #328)
• Fix convex map hover and selection (PR #368)
• Allow generating multiple isovists by importing a CSV file
• Fix a case where VGA progress bar would end, but analysis would still be going (PR #323)
• Fix tableview display (When an attribute is selected from the index, the table is sorted by the same column. When a column is sorted at the table it is also selected on the attribute index)
• Update the Map display to be visible through Remote desktops (PR #379)
• Make sure the correct tool is actually selected when creating a new file (PR #349)
• Set the minimum macOS/OSX version to 10.9
• Add icons to macOS bundle
• Add icons to the linux AppImage
• Fix convex/axial map linking

Command-Line Interface (CLI):

• Allow for printing analysis progress
• On error do not display whole help text
• Allow importing to a datamap (preserving attributes)
• Allow unmerging pixels
• Allow for weighted axial analysis
• Let the user know when a radius list is required for axial analysis

Minor bugs and fixes not included, but may be found here: https://github.com/SpaceGroupUCL/depthmapX/milestone/4?closed=1

This is a quite significant release as the internals of the application have been modernised making it more future proof and easier for new developers to access and contribute. With this release depthmapX will also be more robust and not crash as often as previous releases when handling different data and analyses. More details about user-facing changes can be found here and internal changes here
