    • Parser update for Cake.
    • Added a configuration option to control the display of tournament equities (Window: Preferences: Equity Display):
      • Total Regular Prizes: This is the "classic" mode and displays equities as a percentage of the tournament's total regular prize pool. This total excludes bounties, so bounty calculations have equity totals of 100% + #players x bounty.
      • Table Equity: This mode normalizes equities so the sum of EQPre% values on the table equals 100%. For single table calculations this means the equities are displayed as percentage of the remaining prizes to be awarded, including bounties. The normalization factor can be displayed by hovering over the hand tab header.
    • The new "Table Equity" mode is intended to simplify working with large MTT calculations where EQDiffs% in relation to the total prize pool can become unhandily small. This mode also avoids inflated equities in bounty calculations by including bounty payoffs in the total.
