Recent updates and enhancements.

May 14th, 2025

Latest Protocol Support (1.20.5 - 1.21.5), and bot core testing suite

This update delivers massive improvements to version support and core stability. It includes dozens of critical protocol fixes, internal improvements, UI quality-of-life upgrades, and important macro additions. This was achieved through massive efforts going into automated testing, including unit testing, and integration testing.

Currently we have over 8000 tests (468 integration tests, 8068 unit tests) that run on every update. Most of the effort on the current update was spent writing the test system, the tests themselves, and fixing bugs that get revealed.While the current system covers a lot of the core functionality, it does not yet cover plugins, macros, or commands. This will be the focus for next update, bringing the needed stability to plugins and advanced actions.

Architectural Enhancements to Improve Stability

Following up on our previous update, we are pleased to announce the completion of significant architectural improvements designed to enhance the stability of our service.

We have successfully implemented a per-user profile process isolation system. This advancement ensures that, in the event of unexpected issues such as rare memory leaks, only the affected user's bot will be impacted, while the rest of the system remains unaffected. This will not only minimize disruptions but also enable us to identify and resolve bugs more efficiently, allowing us to address the infrequent crashes more swiftly.

Major System Updates and New Features

Per-user profile process isolation system.

Bot updates will no longer stop profiles (update applied on next start).

Minor Features and Enhancements

Improved notifications/alerts styling to help distinguish between text and links.

Misc fixes and changes done while re-working the system.

Bug Fixes

Fixed the main dashboard page showing from item names from plugins (wrong id conversion to text).

Fixed memory leaks caused by CancellationTokens.

Fixed profile create failing if Compass is selected in Hub Navigation section.

Fixed proxy checking progress numbers getting out of sync.

Stability Enhancements and Bug Fixes

Our team continues to upgrade and scale our servers, networking infrastructure, and system architecture. This update primarily addresses general bug fixes and improvements to overall stability.

Significant progress has been made since the Pre-Production Release, but there is still considerable work ahead. Upcoming updates will continue to focus on bug fixes and further stability enhancements, before we start adding new features and plugins.On a more technical note, we are in the process of transitioning critical architecture components to ensure that each profile operates in isolation. This change is expected to enhance performance and significantly improve system stability for all users.

Major System Updates and New Features

Revamped networking infrastructure.

Introduced 'Join Game Message Settings' in profile settings.

Refactored the process for loading, validating, transmitting, and handling settings across profiles.

Initiated development on new distributed system architecture; moved beta servers to a new environment to prepare for system testing.

Minor Features and Enhancements

Added 'Is In Current Lobby' macro component to verify if a specified account is in the bot's server account list.

Introduced Repeat macro component.

Updated macro components to default to 'Run Once' rather than 'Infinite Loop.'

Improved the clarity of the 'Is Account' macro component variable.

Bug Fixes

Resolved issue with the 'Register Settings' profile setting not functioning correctly.

Fixed plugins halting execution when any bot disconnects until the profile is restarted.

Corrected an issue where newly added account sessions were not cached as valid, preventing accounts from joining a server until rechecked.

Fixed a crash in the UI caused by certain skull skins, which resulted in the inventory getting stuck in an infinite loading screen.

Enhanced proxy scraping process with early pre-checks.

Fixed a crash in the farmer plugin when no replant target was found.

Resolved error logs generated when a macro was paused mid-execution.

Fixed a crash in the profile caused by the Discord Notification Service.

Resolved crashes caused by expired chunks.

Resolved an issue with the 'Simple Number Input' control in macros not saving its state.

Fixed rare cases where server IP addresses were not properly resolved, causing the profile's bots to be stuck at the 'Connecting' state.

Beta servers have been restored and are now operational.
