NewTon DC Tournament Manager v5.4.1 — October 9, 2026

Download v5.4.1

Overview

Double and single elimination now take up to 48 players. The bracket stays a 32-player bracket, and the players above 32 make it in through qualifiers, a round before round 1. A night that grows past 32 never has to turn anyone away.

Qualifiers were asked for by other clubs using NewTon. They are built the way Round Robin was: on the three foundations (the progression rules, the match history and undo), adding to them without changing them. A tournament of 32 or fewer runs exactly as before.

Round Robin, released yesterday, gets three improvements as well: groups of up to five or six, the cups’ own match lengths, and a fairer A cup when there is no B cup.


Qualifiers

At 48, every round 1 match has one qualifier winner and one player who went straight in.

The draw


A Qualifier Only Decides Who Gets to Play


Qualifiers on the Night


Round Robin

Largest group

A new setting in Global Settings → Round Robin: 4 (the default, as before), 5 or 6. The draw makes the fewest groups it can, still an even number, so a larger limit means fewer, longer groups:

In a group of five, the player sitting a round out referees. Fifth and sixth places go on to the cups like everyone else.

The cups’ own match lengths

The A and B cups used the single elimination lengths. They now have their own under Match length → Groups and cups: cup rounds (every round before the semifinals), cup semifinal, cup bronze final and cup final, so a Bo7 cup final no longer changes your normal single elimination nights. Existing settings carry over: the cups start with the lengths they had.

Without a B cup, the top two of each group

Top half is there to keep the B cup from being tiny. Without a B cup there is nothing to protect, so the A cup now always takes the top two of each group when Play the B cup is off. Before, Top half without a B cup could leave a group runner-up out of the only knockout (12 players in four groups of three gave an A cup of six). Draw the cups shows the change as you flip the switch.

Migration

No migration required. Fully compatible with all existing tournament data, match history, Analytics and settings. Qualifiers and the new settings are stored in new fields; tournaments and settings without them work exactly as before, and the cups keep the lengths they had. The export format is unchanged. A tournament with qualifiers needs v5.4.1 or later to open.

This release moves :latest forward to v5.4.1. Installed Chalker apps refresh automatically on their next online launch.
