Carton adds, changes and deprecates some features between major
releases in backward incompatible ways. Here's the list of major
changes between versions. See \f(CW\*(C`Changes\*(C'\fR file for more details.
.SS "v0.9 to v1.0"
.IX Subsection "v0.9 to v1.0"
.IP "\(bu" 4
\&\f(CW\*(C`carton exec \-Ilib\*(C'\fR is deprecated. You must pass the optional include
path to perl interpreter in the normal way, like:
.Sp
.Vb 1
\&  carton exec perl \-Ilib myscript
.Ve
.Sp
Or make your script to take its own \f(CW\*(C`\-I\*(C'\fR option, like many command line
launcher does (i.e. plackup, prove)
.Sp
.Vb 1
\&  carton exec plackup \-Ilib myapp.psgi
.Ve
.IP "\(bu" 4
\&\f(CW\*(C`carton.lock\*(C'\fR is now \f(CW\*(C`cpanfile.snapshot\*(C'\fR. Its name and file format
has been changed. There's no automatic migration, but you can do:
.Sp
.Vb 2
\&  # run with Carton v0.9.64
\&  > carton install
\&
\&  # upgrade to Carton v1.0
\&  > cpanm Carton
\&  > carton install
\&  > git add cpanfile.snapshot
\&  > git rm carton.lock
.Ve
.Sp
This process will most likely preserve modules in your local library.
.IP "\(bu" 4
cpanfile is now a requirement, and extracting requirements from build
files (\f(CW\*(C`Makefile.PL\*(C'\fR, \f(CW\*(C`Build.PL\*(C'\fR) is not supported.
