🚀 Pre-release 2025.11.4

We’re excited to announce the pre-release of version 2025.11.4.beta1!

🌟 What’s New

New Reworked Leaderboards

Note

This change is the implementation of https://github.com/orgs/KoG-teeworlds/discussions/40

Caution

Leaderboards are currently in early access and might not be feature complete and/or finishes might be missing on the leaderboard. DONT worry, all finishes are stored and will be visible at a later stage. Do NOT open a ticket.

We’re implementing a new tiered verification system to better represent the competitive team spirit of KoG and ensure leaderboard integrity. This update introduces four distinct verification levels that more accurately reflect the quality and accountability of recorded finishes.

A finish might be in different stages at specific times, after a period of 15 days it should be in the final stage.

🏆 Verified Finish (Gold Standard)

The highest tier of verification requires:

• .teehistorian recording exists
• All players logged in (no anonymous players)
• Team play (team 0 excluded)

This ensures that verified finishes represent authentic team gameplay with full player accountability.

🥈 Verifiable Finish (Silver)

A solid verification level requiring:

• .teehistorian recording exists

This tier maintains good verification standards while being more accessible than the gold standard.

🥉 Accepted Finish (Bronze)

A basic verification level where:

• Some extent of verification is available

This tier accommodates finishes with partial verification data.

❓ Unverified Finish

For finishes where:

• No verification information is available

These finishes remain visible but are ranked separately from verified entries.

New Clans (Early Access)

We’re excited to introduce the new Clan system! To ensure a stable and polished experience, we are launching this feature in a limited Early Access phase.

Caution

Please note: The Clan system is currently in a closed Early Access program and is not yet available to everyone. We are starting with a small number of selected clans to gather feedback. Our support team does not have information on a timeline for a general release.

How to Apply for Early Access

If your clan meets the requirements below, you can apply for consideration.

1. Submit a clan request through the website.
2. After submission, please open a support ticket to request an administrative review.

Selection is at the discretion of the administration team. As this is a closed program with limited slots, we may not be able to provide feedback on all applications.

Early Access Requirements

• The designated Clan Leader must be ranked in the Top 200 for Fixed Points.
• The application must include a list of at least 30 confirmed members.
• The Clan Leader must have a clean account history on KoG with no prior punishments.

Clan management interface

If you are in a clan, you’ll have a new menu called “Clan” in the upper right corner after you are logged in.

You are able to click on it to get redirect to the clan dashboard where you can see the current status of your clan.

Clan features are usually gray, indiciating that they are not activated. If they are blue, your clan members do have access to this certain feature.

🐛 Bug Fixes

• Fixed an issue with the player disconnect event handling. (Internal report)
• Resolved several power collection and activation bugs. KoG-teeworlds/community#32
• Fixed logging inconsistencies that affected server monitoring. (Internal report)
• Patched configuration-related bugs affecting server startup. (Internal report)

New MapEvent Probability Matrix

The MapEvent Probability Matrix explains how likely it is that a player finish will trigger a Custom Random Map Event. Every finish counts as a roll, the probability is calculated based on the level of the map and the difficulty of the event. The probability is calculated by the following formula:

$$\text{max\_levels} = 16 \\ \text{max\_length} = 9 \\ \text{level\_weight} = 0.6 \, (60\%) \\ \text{length\_weight} = 0.4 \, (40\%) \\ \text{matrix}[\text{length}][\text{level}] \, \text{retrieved from the table}$$

Probability Formula:

$$\text{probability} = \left( \frac{\text{level}}{\text{max\_levels}} \cdot \text{level\_weight} \right) + \left( \frac{\text{length}}{\text{max\_length}} \cdot \text{length\_weight} \right) \cdot \text{matrix}[\text{length}][\text{level}]$$

Example Calculations:

1. Extreme 3+ on a WTF map:

$$\text{level} = 16, \, \text{length} = 9, \, \text{matrix}[9][16] = 0.0914 \\ \text{probability} = \left( \frac{\text{16}}{\text{16}} \cdot \text{0.6} \right) + \left( \frac{\text{9}}{\text{9}} \cdot \text{0.4} \right) \cdot 0.0914 \\ = 1 \cdot 0.6 + 1 \cdot 0.4 \cdot 0.0914 \\ = 0.6 + 0.03656 = 0.63656 \cdot 100 = 63.66\%$$

2. Easy 1 on a XXS map:

$$\text{level} = 1, \, \text{length} = 1, \, \text{matrix}[1][1] = 0.0198 \\ \text{probability} = \left( \frac{\text{1}}{\text{16}} \cdot \text{0.6} \right) + \left( \frac{\text{1}}{\text{9}} \cdot \text{0.4} \right) \cdot 0.0198 \\ = 0.0625 \cdot 0.6 + 0.1111 \cdot 0.4 \cdot 0.0198 \\ = 0.0375 + 0.00087912 = 0.03838 \cdot 100 = 3.84\%$$

Community Documentation

Oct 1, 2024

Project Maintainer

We are excited to announce the release of our comprehensive documentation on Community Governance and the KoG Project Charter. This initiative marks a significant step forward in our commitment to fostering a transparent, trustworthy, and community-driven environment.

Building Trust Through Transparency

Transparency is the cornerstone of any community. By openly sharing our governance structures, decision-making processes, and project mission, we aim to build and strengthen the trust between all members of our community. This documentation provides clear insights into how our project operates, who is responsible for various roles, and how decisions are made and implemented.

Empowering Community-Based Steering

Our community is at the heart of everything we do. By outlining our governance model and project charter, we empower every member to understand how they can contribute, participate in leadership roles, and influence the direction of the project. This approach ensures that the project evolves in a way that reflects the collective vision and values of our community.

What You Will Find in the Documentation

• KoG Governance: An overview of our governance structure, including the roles of the Governing Board, Working Groups, Chapters, and Committees.
• Roles and Responsibilities: Detailed descriptions of the various roles within the project and how community members can step into leadership positions.
• Voting Process: A transparent explanation of how decisions are made, including voting procedures and how disagreements are resolved.
• KoG Project Charter: A comprehensive outline of our project’s mission, governance policies, code of conduct, and more.

Enhancing Accessibility with Visual Aids

To make the documentation more accessible and easier to understand, we’ve included informative diagrams and flowcharts. These visual aids help demystify complex processes and provide a clear picture of how our community functions.

We believe that a project guided by its community is stronger, more innovative, and better equipped to meet the needs of its members. We invite you to read through the documentation, participate in discussions, and contribute your ideas and expertise.

Together, we can build a vibrant and inclusive community that not only achieves our project goals but also sets a standard for openness and collaboration.
