Conda-forge doesn't have tensorflow 1.15 anymore?
Hi,

Thanks for reporting the issue.

`conda-forge` is community build TensorFlow which we don't have any control on.

For 1.15 version, you can refer to the official `PyPi` release from `TensorFlow` here https://pypi.org/project/tensorflow/1.15.0/.

However, it is suggested to use latest `TensorFlow` (2.14 as of now) for bug fixes and newly added feature and from TensorFlow 2.0 onwards, eager mode is the default behavior. Ok thanks for the information! Are you satisfied with the resolution of your issue?

### Current behavior?

I have an old project that uses tensorflow 1.15, but recently I can't install the conda environment for this anymore. The version no longer exists on conda-forge, for some reason?
There are versions 1.14 and lower, and 2.*, but no longer 1.15? Why is that?

### Standalone code to reproduce the issue

```shell
conda create --name tf1 python=3.7
conda activate tf1
conda install -c conda-forge tensorflow=1.15
```
