DC Studio 0.2.1

DC Studio 0.2.1

Fixed

• Opening a PGN file for the first time showed zero games (0.2.0). The cache was created and then judged "fresh" because it was newer than the file. First opens import again, and any empty cache 0.2.0 left behind is rebuilt on the next open.

Apple Silicon Mac, macOS 14 (Sonoma) or later.

Download DC-Studio-0.2.1-arm64.dmg, open it, drag DC Studio into Applications.

The build is ad-hoc signed but not notarized, so the first launch is
blocked with Apple could not verify "DC Studio" is free of malware…
That dialog offers no way to continue — dismiss it without letting it move the
app to the trash, then either run

xattr -dr com.apple.quarantine "/Applications/DC Studio.app"

or open System Settings ▸ Privacy & Security and click Open Anyway
next to the message about DC Studio.

Databases

• One window per PGN file, tabbed. Open files come back on launch, each on the game you were looking at. A file is opened once; opening it again brings its tab forward. Only the front tab's engine runs.
• Copy games between tabs (right-click ▸ Copy to). Duplicates — same start position, same main line — are skipped.
• A file changed by another program while open is flagged: Reload or Keep Mine.
• Filter the list by result, date range and Elo; Result and Black Elo sort.

Analysis

• Analyze Game (⌥⌘A): marks the losing moves ?! ? ??, writes what the eval did, inserts the engine's line beside each. Both sides or one; main line or every variation. One undo step.

Notation and paper

• Figurines (♘f3) on screen and in print; Game ▸ Figurine Notation to switch.
• Diagrams (⌘D), stored as $220 so they round-trip through ChessBase.
• Print Game (⌘P) and Export as PDF.
• Merge Selected Games: several games into one tree, comments included.
• Null moves (--) in analysis PGNs now parse, replay and save.

Reference

• Opening statistics from lichess: Masters, Lichess (rating band and speeds of your choosing) and Player (a lichess username's own games). Needs your own lichess API token — one click from the panel's ⚙ — kept in the Keychain.
• Novelty: a move the chosen book has never seen is called out, with a button to write the N mark.

Fixed

• The sample fixture carried an illegal move; replaced with six classics.

DC Studio 0.1.0

Apple Silicon Mac, macOS 14 (Sonoma) or later.

Download DC-Studio-0.1.0-arm64.dmg, open it, drag DC Studio into Applications.

The build is ad-hoc signed but not notarized, so macOS quarantines it on
first launch. Clear that once:

xattr -dr com.apple.quarantine "/Applications/DC Studio.app"

GUI equivalent: try to open the app, then go to System Settings ▸ Privacy &
Security and click Open Anyway.
