Dear *,

I'd like to study old versions of the P4 specification [1]. Sadly
p4.org/spec does not list all existing (=published) versions [2], but
only P_14 (1.0.3) and the 2016-12-16 draft of P_16.

1. Where can I find earlier specifications of P4?
2. Why are older specification versions not listed on p4.org/spec?



[1]: Motivation is a software written for a previous P4 specification
version. Without the specification it was written against, I'm unable to
figure out in which shape it is.   More generally: all examples
published to explain P4 will suffer, in the long term, if people are
unable to access the specification that was current when the example was
published. (May sound a bit pessimistic, but hopefully gets my point

[2]: According to P4_14 1.0.3 at least the following exist: 1.0.0-rc1,
1.0.0-rc2, 1.0.0-rc3, 1.0.1, 1.0.2, 1.0.3
