.SS "Release 1.5"
.TP 2n
.if t \(bu
.if n *
The
.I c_incl
program now correctly prints the names of absent include files,
causing them to be cooked correctly in a greater number of cases.
.TP 2n
.if t \(bu
.if n *
Recipes with no ingredients are now only
applied if the target is absent.
To still use the previous behaviour,
use the "set force" clause on the recipe.
.TP 2n
.if t \(bu
.if n *
It is now possible to supplement the last-modified time with a fingerprint,
so cook does even fewer unnecesary recompilations than before.
Put the statement
.RS
.ft CW
set fingerprint;
.ft R
.RE
somewhere near the top of your
.I Howto.cook
file for this to be the default for your project.
.TP 2n
.if t \(bu
.if n *
There is a new form of include directive:
.RS
.ft CW
#include-cooked \fIfilename\fP...
.ft R
.RE
When files are included in this way,
.I cook
will check to make sure they are up-to-date.
If not, they will be cooked,
and then
.I cook
will start again and re-read the cookbook.
This is most often used for maintaining include-dependency files.
.TP 2n
.if t \(bu
.if n *
.B Cook
now configured using a program called
.IR configure ,
distributed with the package.
The
.I configure
program is generated by GNU Autoconf.
See the
.I BUILDING
file for more details.
.TP 2n
.if t \(bu
.if n *
The semantics of
.I search_list
have been improved.
It is now guaranteed that when ingredients change they
result in targets earlier in the
.I search_list
being updated.
.TP 2n
.if t \(bu
.if n *
There is now a
.I make2cook
translator,
to translate
.I Makefile
files into
.I Howto.cook
files.
Most of the GNU Make extensions are understood.
There is no exact semantic mapping between
.I make
and
.I cook,
so manual editing is sometimes required.
See
.IR make2cook (1)
for more information.
.TP 2n
.if t \(bu
.if n *
.I Cook
now understands archive member references,
in the same format as used by
.IR make ,
et al.
Archive member references benefit from stat caching and fingerprinting,
just as normal files do.
