What was this change? When? What was the rationale for doing it?

Arguing that something is bad because "I was told so" makes it pretty
difficult for anybody to give you sensible answers.

What prevents you from fixing it? Or paying someone to fix it?

Generally if some software is left unchanged for two years, with not
even bug fixes, I start suspecting noone uses it. 

For isntance: where can I find the latest versions of:

  phpagi (homepage lists latest version as released on 2005)

A case to the other way:

We would all appreciat suggestions on how to better do changes. Again,
please be more specific.

SetCallerID et. al. were declared deprecated in the 1.2 cycle. If you
wrote a new dialplan in Asterisk 1.2 and used them, you really
misbehaved and it's quite difficult blamind the Asterisk developers for
that. They asked you explicitly not to.

(I have quite a few DOS games that badly react to higher clock speeds,
and are thus unusable. Many other DOS programs that access the hardware
directly in strange ways and thus fail in most emulated environments suc
as Windows NT and DosEMU.

Analogies are nice, but are not always relevant. Please stick to the

I suggest making specific comments to that thread.
