Let's get to know the full meaning of the version number.

Second number: Minor version, added some new features or changes under the premise that the main version schema is unchanged

Third Number: Incremental version,bug fix , detail perfect

M: Precursor of milestone version, beta version, release version

As can be seen, now spring5.0.0.m from release version still has a distance, but even out of 5.0.0.RELEASE, unless it is a new project or functional needs, there is no need to rush to upgrade, because it is usually not perfect, there are some bug need to repair. Generally, when the 5.1 came out, representing the official has shifted the center of gravity to 5.1, then it can be thought that the largest version of 5.0.x.release has been more perfect.
