What’s New in The Sims 4?

Family Tree Updates!

The Family Tree has been updated to expand how you experience and tell Sims’ family stories. Your Sims now have relationship labels for in-laws, half siblings, great grandparents, and more! Extended family members will also be shown in the family tree. Players can also choose whether adopted Sims are labeled as such in the Family Tree.

New relationship labels include: Mother-in-Law, Father-in-Law, Sister-in-Law, Brother-in-Law, Daughter-in-Law, Son-in-Law, Distant Relative, Distant Relative-In-Law, Half-sister, Half-brother, Stepmother, Stepfather, Stepdaughter, Stepson, Great-grandmother, Great-grandfather, Great-grandson, Great-granddaughter, Parent’s Cousin, Cousin’s Child, Grandniece, Grandnephew, Grand-aunt, Grand-uncle, Ancestor, Descendant, and Relative-In-law. Divorced has a new name: Ex-Spouse, and Deceased Spouse has a new name: Late Spouse.

Close relatives are prohibited from being romantically involved. This prevents autonomous flirting between In-Laws or Step-relatives.

Flared Staircases!

Get ready to create grand looking staircases! Now, you can widen the top or bottom of a staircase (symmetrically or asymmetrically) to give your builds a touch of elegance. Additionally, stair rails can now be applied to only one side of a staircase and we’ve added a slider to change the length of the rail.

What This Means for Gameplay

For builders, this Sims 4 February 2026 Patch finally removes some long-standing frustrations with stair customization. Being able to control railings more precisely opens up cleaner layouts and more realistic designs. Flared stairs add instant drama and elegance to both modern and traditional homes.

Story focused players will notice the improved Family Tree right away. Seeing clearer connections between relatives makes legacy gameplay feel more detailed and intentional. CAS also feels smoother thanks to updated filters that make finding themed content faster. Combined with the new event challenges and a large batch of bug fixes, gameplay overall should feel more polished and less interrupted.

The Sims community has been buzzing about this update because it delivers features players have been asking for for years. Stair improvements alone have builders celebrating, while legacy players are thrilled to finally see deeper family tracking without mods. The addition of nails and CAS tweaks adds some fun style refreshes that feel very timely.

There is also a lot of excitement around how this patch sets the stage for Royalty & Legacy. Seeing systems and filters update ahead of release makes the expansion feel closer and more real, which always gets Simmers talking.
