fwiw, I think although the root causes are similar, the differences |
| 32 |
between the major GCC versions probably warrant their own separate news |
| 33 |
items, unless there is updated information relevant to first-time |
| 34 |
viewers. I'd probably constrain the existing news items closer to |
| 35 |
~sys-devel/gcc-5 perhaps - or >= gcc-4.7 <gcc-6 or some-such - at the |
| 36 |
appropriate discretion, to avoid the immediate problem you assert. |
| 37 |
|
| 38 |
I'm not sure news has the facility to re-mark-unread existing 'read' |
| 39 |
"old" news items, and thus re-display to users who've already seen the |
| 40 |
original. |
| 41 |
|
| 42 |
As a conservative user still using gcc-4.9 (for now, but ready to take |
| 43 |
the plunge on gcc-5 [Yes, really!]) I would welcome a TL;DR on the |
| 44 |
things to watch out for when building apps with the new major versions |
| 45 |
of GCC going forward. |
