cross-compiler. See the "Cross building Guile" section of the README,
for more on how to cross-compile Guile itself.
** The return of `local-eval'.
Back by popular demand, `the-environment' and `local-eval' allow the
user to capture a lexical environment, and then evaluate arbitrary
expressions in that context. There is also a new `local-compile'
command. See "Local Evaluation" in the manual, for more. Special
thanks to Mark Weaver for an initial implementation of this feature.
** Fluids can now have default values.
Fluids are used for dynamic and thread-local binding. They have always

information. `current-input-port', `current-output-port', and
`current-error-port' are now parameters.
** Add `current-warning-port'
** Add `current-warning-port'.
Guile now outputs warnings on a separate port, `current-warning-port',
initialized to the value that `current-error-port' has on startup.

it does so without actually calling `setlocale'. Please report any bugs
in this facility to bug-guile@gnu.org.
** One-armed conditionals: `when' and `unless'
Guile finally has `when' and `unless' in the default environment. Use
them whenever you would use an `if' with only one branch. See
"Conditionals" in the manual, for more.
** `current-filename', `add-to-load-path'
There is a new form, `(current-filename)', which expands out to the
source file in which it occurs. Combined with the new
`add-to-load-path', this allows simple scripts to easily add nearby
directories to the load path. See "Load Paths" in the manual, for more.
** `random-state-from-platform'
This procedure initializes a random seed using good random sources
available on your platform, such as /dev/urandom. See "Random Number
Generation" in the manual, for more.
* New interfaces
** (ice-9 session): `apropos-hook'
** New print option: `escape-newlines', defaults to #t.
** (ice-9 ftw): `file-system-fold', `file-system-tree', `scandir'
** `scm_c_value_ref': access to multiple returned values from C

Search the manual for these identifiers and modules, for more.
