The space.com article stated: "We investigated Kepler-186f, which is the first discovered Earth-sized planet in a habitable zone. The habitable zone is an area around a star where liquid water can exist on the surface of the planet and life may be able to emerge and thrive." "Unlike Earth, Kepler-186f is located far from the other planets in its solar system. As a result, these other planets have only a weak effect on its orbit and movement. So, Kepler-186f generally has a fixed obliquity, similar to Earth. Even without a large moon, it doesn’t have wildly changing or unpredictable seasons like Mars. Looking forward, more research into exoplanets will help scientists understand what seasons look like throughout the vast diversity of planets in the universe."
Kepler-186 is a multi-planet system. Kepler-186 f has an eccentricity = or larger than 0.04 which should impact its weather and season I suspect.
Detailed information about planet Kepler-186 f and its parameters.

The .eu site shows 890 solar systems now, none are like our solar system and a confirmed, Earthlike planet with life thriving on it. Somewhat more solar systems are at the Nasa exoplanet archive site.
