I guess it is a matter of interpretation then, "there will be no further |
| 19 |
releases" means end of life, to me anyway. |
| 20 |
|
| 21 |
I do agree that we aren't sure about 5.3, but "there will be no further |
| 22 |
releases" is pretty clear to me. |
| 23 |
Older than lua 5.3 is dead. |

Some of the arches you listed are not stable, so I don't think we have |
| 44 |
to worry about those arches (see arches.desc). If the arch isn't stable, |
| 45 |
we can't guarantee anything. |
| 46 |

There is activity in luajit upstream, so hopefully they will do a new |
| 48 |
release that supports the newer lua versions. I do agree that it is |
| 49 |
problematic that they only support lua 5.1. |
