Season

In Star Trek Online, a Season, or "story update", is analogous to is a significant game patch introducing new features or content. These content updates are called seasons in Star Trek Online in reference to the television show. Season numbering has remained consistent between PC and Console releases, despite seasons 1-11 being released at launch for console.

Expansions
Larger updates are called Expansions and not kept within the standard numbering scheme. The Legacy of Romulus, Agents of Yesterday, and Victory is Life expansions introduced a new playable faction, while Delta Rising focused on endgame content.

Season 15 to Season 17 were termed an "expansion-over-time" by the developers, indicating the equivalent of expansion-level content focusing on Star Trek: Discovery spread over 3 seasons rather than as a single release.

Mid-season updates
Since Season 8, Star Trek Online has had smaller updates in between the major seasonal releases. These are named after the current season with .5 added to indicate its placement. Mid-season updates can also occur for the larger expansions; for Delta Rising it was merely called a mid-season update with no number, and for Agents of Yesterday it was given the subtitle Artifacts.

Consoles delay
Due to delays in patching out to consoles, PS4 and Xbox players receive Seasons one or two months later than PC players.
