h5py windows requirement for hdf5 (1.8.15.1)

[MSeifert04]

The "relativly" recent change in the h5py recipe (restricted to hdf5 1.8.15.1 on windows) leads to alternating updates and downgrades between h5py 2.6 and hdf5 1.8.16.0 and h5py 2.7 and hdf 1.8.15.1 on my computer:

The following packages will be UPDATED:

    bottleneck:   1.2.0-np112py35_0  --> 1.2.0-np111py35_0
    hdf5:         1.8.15.1-vc14_4    [vc14] --> 1.8.16-vc14_0      [vc14]
    matplotlib:   2.0.0-np112py35_0  --> 2.0.0-np111py35_0
    numba:        0.31.0-np112py35_0 --> 0.31.0-np111py35_0
    numexpr:      2.6.2-np112py35_0  --> 2.6.2-np111py35_0
    pandas:       0.19.2-np112py35_1 --> 0.19.2-np111py35_1
    pywavelets:   0.5.2-np112py35_0  --> 0.5.2-np111py35_0
    scikit-image: 0.13.0-np112py35_0 --> 0.13.0-np111py35_0
    scipy:        0.19.0-np112py35_0 --> 0.19.0-np111py35_0
    statsmodels:  0.8.0-np112py35_0  --> 0.8.0-np111py35_0

The following packages will be DOWNGRADED due to dependency conflicts:

    h5py:         2.7.0-np112py35_0  --> 2.6.0-np111py35_1
    numpy:        1.12.1-py35_0      --> 1.11.3-py35_0

and next time:

The following packages will be UPDATED:

    bottleneck:   1.2.0-np111py35_0  --> 1.2.0-np112py35_0
    h5py:         2.6.0-np111py35_1  --> 2.7.0-np112py35_0
    matplotlib:   2.0.0-np111py35_0  --> 2.0.0-np112py35_0
    numba:        0.31.0-np111py35_0 --> 0.31.0-np112py35_0
    numexpr:      2.6.2-np111py35_0  --> 2.6.2-np112py35_0
    numpy:        1.11.3-py35_0      --> 1.12.1-py35_0
    pandas:       0.19.2-np111py35_1 --> 0.19.2-np112py35_1
    pywavelets:   0.5.2-np111py35_0  --> 0.5.2-np112py35_0
    scikit-image: 0.13.0-np111py35_0 --> 0.13.0-np112py35_0
    scipy:        0.19.0-np111py35_0 --> 0.19.0-np112py35_0
    statsmodels:  0.8.0-np111py35_0  --> 0.8.0-np112py35_0

The following packages will be DOWNGRADED due to dependency conflicts:

    hdf5:         1.8.16-vc14_0      [vc14] --> 1.8.15.1-vc14_4    [vc14]

Was it wrong to post it here? Is this rather a conda issue?
