- To help managers understand the situation better, we have restored the event: "Offensive rebound because the player wasn't boxed out." This will be displayed when an offensive rebound occurred because the defending team failed to box out opponents.

2023-12-17
1.6.2
- Bug fix: Resolved an issue where the team advanced to the frontcourt without spending any time at all. These situations occurred after the event "fast break was halted due to tiredness".

- Fixed a bug where, after an offensive rebound during a fast break, the ball went to the other side of the court.

2023-11-13
1.6
- Increased SF players’ involvement in the offense. We noticed that SF players had been scoring less points than players of all other positions, therefore we have increased the amount of passes received by SF players.
- Players with bad dribbling often made turnovers in the fast breaks, even in perfect situations. Now, if that happens, they won't rush into fast breaks for the rest of the match.
- Added fast break turnovers to the failed fast break statistics on the after-match information page.
- Fixed the 8-second violation bug, which incorrectly displayed the wrong team name in the event text.
- Reduced the number of events: "due to good preparation of defending team's coaches attack wasn't finished with shot"
- Resolved the bug where a fast break in the last attack resulted in a shot from the other side of the court, even with ample time remaining.
- Adjusted home court events, distributing them more evenly throughout the entire match instead of being concentrated in the first half.
- Shortened the duration of early attacks, and positional attacks will now start a bit sooner.

2023-09-11
1.5
- New version released. All testing Match engine updates included (1.5-b.1)

2023-09-05
1.5-b.1
- Home court advantage increased.
- Several new events related to home court advantage have been added, thus reducing the home court's impact on free throw percentage.
- Reduced the "relaxation due to big points difference factor"
- Consuming time at the end of matches will now be 1-2 seconds shorter, thus giving more time for leaders to make passes and shots.
- Fixed a bug that some events in the end of match were missing in play-by-play. For example, a player let the ball go out of bounds, which occurred in the last seconds of the game when a shot was blocked, resulting in an attack clock violation.
- Maximum number of 8-second violations reduced by more than half.
- Fixed a few other small bugs.

2023-07-17
1.4.1

2023-01-11
1.4-b.2
Bug fix: Fixed missing back court inbounding scenarios in the 4th quarter and overtimes.

2023-01-10
1.4-b.1
-Bug fix: wrong player with the ball after event “gained a loose ball”
-Rebound calibration:
--More chances to get defensive rebound despite criteria
--A bit increased chances for rebound, when Defence Focus or Offence Focus is low post.
--A bit decreased committed fouls influence when fighting for defensive rebounds.
--In close range usually bigger players are fighting for rebound. However we reduced this effect for “distant rebound”

2023-01-09
1.3.1
- In the last attack the ball goes to the point guard - in order to have better chances to avoid losing it in case of pressure.

2023-01-02
1.3
- New version released. All testing Match engine updates included (1.3-b.1 - 1.3-b.5)

2022-12-29
1.3-b.5
- Bug fix: after a free throw, rebound usually goes to C or PF, with little chances to grab the ball for SF.
- Rebounds calibration - more often C/PF position players will fight for rebounds.
- Set plays will be done by a bigger range of players.
- After an offensive rebound, shot clock should be reset to 14s, even when there were more than 14s remaining.
- In the last attack sometimes teams started an early attack, therefore the defined tactics did not work.
- Reduced amount of turnovers significantly reduced the influence of dribbling skill. In order to compensate for that, we increased the influence of dribbling skill towards creating a better shooting situation.
- Increased possibility to repeat a shot straight after an offensive rebound.
- More often a fight for rebounds will take place in a close range. 
- Decreased shooting effectiveness from the three point range. Consequently, increased shooting effectiveness from the close range.

2022-12-21
1.3-b.4
Pick&Roll updates:
- More information added to events
- Additional balancing. Pick&Roll is more effective when the ball handler and screen player can shoot from multiple positions.

2022-11-26
1.3-b.3
Bug fix: two passes to the same person in a row (without any other event) when advancing to frontcourt

2022-11-23
1.3-b.2
- New event: “Player is trying to inbound the ball”
- At the end of the quarter the ball was passed to PG or SG. Sometimes that led to situations when the final attack was organized by SG who is not great in dribbling or shooting. Now the player will be selected more carefully regarding skills and tactical settings. 
- Reduced amount of turnovers when passing

2022-11-18
1.3-b.1:
- Home team will have some home court advantage even with 0% atmosphere.
- Deflections and steals adjustments:
— one event instead of two displayed in Play-by-play when deflection was done by kicking the ball. 
— reduced the number of deflections.  
— steal after deflection should be granted to the player who deflected the ball (not to the player who caught the ball)
— new event: The team wants to avoid deflections and will try to be more careful this period 
— new event: The team wants to avoid steals from opponents and will try to be more careful this period
– New limit included - how many more points one team can get from lucky shots (accurate/missed) compared to the opponent team.

2022-10-30
1.2
- New version released. All testing Match engine updates included (1.2.0-b.1 - 1.2.0-b.11)
1.2.0-b.11
- Bug fix: attack time violation repeats second time;
- Bug fix: full court press influence towards player's tiredness will depend also on playing time. It used to be the same for all players despite how much minutes they played;
- Increased home court influence;
- Included a safeguard for a player so that he cannot miss more than 30% of his shots due to being unlucky. The limit is applied for each shooting position (close/mid-range/three).

2022-10-25
1.2.0-b.10 
1.1.4
- Bug fix: shot attempted after buzzer event cannot be before the buzzer

2022-10-20
1.2.0-b.9
- Bug fix: shot clock should be reset to 14s when the ball hits the rim after a missed shot.

2022-10-18
1.2.0-b.8
- Bug fix: rebound should take at least one second. 

2022-10-17
1.2.0-b.7
- Significantly increased the amount of deflections
- More deflections are expected when the team tries to pass the ball to the post (when the team uses 'low post' defense focus). Similarly, the effect increased for these types of defense focus: playmakers, leader by skills and leader by points.
- Bug fix: IQ influence in set plays have been reduced. It used to be a lot higher than intended. That way other criteria (such as defensive tactics) were smaller than intended. 
As set plays occur almost every attack, this update significantly changes situations after set plays and the overall outcome. We expect that more balancing will be needed in this area. 

2022-10-06
1.2.0-b.6
- Significantly decreased the 'random' factor in events of offensive fouls while driving
- Until now when player was 'making a drive' only his main defender used to get fouls. From now, other players will also be involved in defensive actions. Thus, others will also be able to get fouls or defend against a drive. 
- Decreased chances of getting a foul during a steal attempt. 

2022-09-30
1.1.3 Bug fix: second chance points were not calculated and did not appeared in the after match information page
1.2.0-b.5 Bug fix: second chance points were not calculated and did not appeared in the after match information page

2022-09-26
1.2.0-b.4
- A bit increased the amount of blocks
- Slightly reduced close-range shooting accuracy (especially, in good and average situations);
- Slightly reduced mid-range shooting accuracy in good situations.

1.2.0-b.2 Bug fix: player with 5 fouls continued playing in court (foul received in the end of 4th quarter)

2022-09-20
1.2.0-b.1 Free throws accuracy was a bit increased (especially for players with bad skills). However, with that we needed to remove experience influence on free throw shooting.
