Editing Halo: The Master Chief Collection Content Updates (2014-2015)

{{Title|''Halo: The Master Chief Collection'' Content Updates (2014-2015)}}
{{Status|RealWorld}}
This page lists all '''Title Updates''' released by [[343 Industries]] for ''[[Halo: The Master Chief Collection]]'' between [[2014]] and [[2015]]. Due to the game's buggy nature at launch, these patches were mostly aimed at bringing the game into a workable state, though due to the amount of work and the game's codebase, no further patches were rolled out for the game following 2015. With the launch of the [[Xbox One X]] in [[2017]], 343 Industries planned to do a 4K update for the game, and ultimately decided to do a total overhaul of the game and provide ongoing support.

Due to the "phased" nature of ''Master Chief Collection'' updates, only the initial rollout of 2014-2015 updates are listed on this page. To see the updates done between [[2018]] and [[2019]] as part of the "#FixMCC" project, see [[Halo: The Master Chief Collection Content Updates (2018-2019)|here]]. To see the patch notes for the individual updates and [[season]]s following the game's launch on PC and the addition of ''[[Halo: Reach]]'' to the collection, please see each Season's individual article (listed at the bottom of this page).

==November Content Update (General)==
Released on November 14, 2014, this Content Update focused on campaign, UI, and some Matchmaking and party issues. Performance focused Matchmaking updates were addressed in another content update the following week.<ref>[https://www.halowaypoint.com/en-us/community/blog-posts/halo-the-master-chief-collection-content-update-11-14-14 '''Halo Waypoint''' ''11.14.14. Halo: The Master Chief Collection Content Update Notes]''</ref>

===List of Changes===
*Fixed a variety of issues that caused players within the same Matchmaking party to be placed on different teams. In rare cases, this issue may still occur, and we are investigating additional fixes.
*Fixed a Matchmaking issue with behind the scenes team skill matching, allowing team skill matching to be more accurate in both ranked and unranked playlists.
*Fixed an issue where the campaign HUD did not reset from level to level with scoring or time HUD enabled. This will clear out the full visualization of level segments, which was previously not reset.
*Fixed a variety of issues with campaign leaderboards and scoring HUD, so now when scores are posted, score, kills, time, deaths, and penalties will be reported correctly for new mission leaderboard entries. We are still working on additional fixes for playlist leaderboard entries.
*Fixed an issue with competitive HUD time split. Now, when players have competitive time HUDs on with a rival set, they will see per-segment split times for whether they are ahead or behind at each segment.
