{{todo|Find the 2.3 changelog.}}
Since its early access launch as ''Shooter Tourneys'' in 2020, {{zamnhlmp|4.1}} has received many updates, ranging from patches, to content overhauls. As of 2025, the game has received 13 major updates, each bringing new maps, player models, and enhancements. In August 2021, when 2.6 released, it marked the start of the '''Seasonal Scheme''' release model which {{Phoenix Software|4.1}} now uses to develop updates for the game.

Throughout its history, Cross Product Multiplayer has used two codebases; in 2019-2020, it used the '''''creaTive Deathmatch Player,''''' and in 2021, it was rewritten as {{Aura|4.1}}. Both codebases are a fork of {{ag|4.1}}.

{{note|All versions of Cross Product Multiplayer older than 2.9.2 have been removed from ModDB but can be found on the Internet Archive.}}

== As ''Shooter Tourneys'' (2019-2021) ==
=== 1.1 (2020) ===
1.1 was released just one day after launch on April 16, 2020. This update served as a hot fix and a minor quality-of-life (QoL) update. It focused on resolving early compatibility issues and enhancing script functionality.
* Fixed incorrect version identifier.
* Fixed custom fonts not rendering correctly on the main menu.
* Added script binds to the Keyboard Options menu for the Gauss Boost.
* Adjusted the Gauss Boost Script to prevent it from locking the FPS to 111.

=== 1.2 (2020) ===
1.2 was released the same day as 1.1, but only on GitHub. It introduced backend improvements and addressed scripting issues. ModDB players would not see these changes until 1.3.
* Fixed the Usespam script not working.
* Removed the broken Quickuse script.

=== 1.3 (2020) ===
Version 1.3 was released on November 30, 2020 and was a content and polish update that introduced a new map, improved audio quality, and made visual enhancements to weapon models. It also reverted an experimental weapon change.
* Added the map '''Boombox.'''
* Updated all weapon viewmodels to use HEV Suit hands.
* Improved the quality of the footstep sound effects.

==== Season 9 Patch IV - 2.9.4 (2025) ====
Version 2.9.4 was released on September 18, 2025. It addressed community feedback following the Steam Release and added new UI elements, and a small set of Achievements.
* Fixed an issue where the Linux version would launch in an incredibly low resolution.
* Added a **tip to open the command menu** to the introduction HUD watermark.
* Fixed an issue where certain maps would crash if the max-players was set to 2.
* The default FPS is now **100** to help with network optimisations and to alleviate an issue where players with high or fluctuant ping may be disconnected from a game due to "reliable channel overflowed."
** Note: We are constantly working to improve the network optimisation in the Multiplayer component of *Cross Product.* If you are facing an issue, please do not hesitate to report it to us in the Steam Discussions.
* Fixed an issue where players were unable to enable OpenGL VSync.
* Implemented proper functionality of the `hud_fastswitch` command. If on, the number keys will instantly switch weapons.
* Fixed an issue where the **RPG** idle animations would cut off.
* Fixed an issue where the **Tau Cannon's** idle animations would never play.
* Fixed an issue where the **Hand Grenade's** draw animation would not replay after throwing a grenade.
* Fixed an issue where certain weapons such as the **Snark** and **Satchel Charge** could not play their deploy animations fully.
* Season 5 versions of **Capture the Flag** and **Domination** have been added.
* Removed reduntant entities from the FGD file for map-makers.
* Fixed an issue in **City** where ambient sound files were unable to be found.
* Fixed a bug in **Forsaken** where falling off the map would cause the red deathscreen to stick for a while.
* Updated the **Instruction Manual.**
** Added useful commands for server operators.
* Headshots now deal 3x damage in **HLDM** to match *Half-Life.*
* Introduced a new damage type to `trigger_hurt` called `DMG_SKIPARMOR`, which ignores armor when dealing damage.
** This is useful for maps that want to deal pure health damage without affecting armor.
** As a result, this has been implemented to **Crossfire's airstrike,** meaning players can no longer avoid the damage by having armor.
* To improve balancing and fairness in most gamemodes, **wallgaussing** has been switched off in every gamemode apart from **HLDM.**
