Comment 31 for bug 1717040

I have a feeling that I don't fully grasp all the implied side effects here,
so if this process feels safer based on your experience, please go ahead.

I don't think the API will be an issue in this upgrade : as stated, all published symbols in v0.5.1 are still published in v1.3.1, so I would expect such application to continue linking properly.

The change of format is another thing, and an application hardwired to deal with v0.5.x experimental format, if such a thing exist, would be surprised to deal with data using v1.x format. So some caution in the transition is indeed welcomed.
