Please send Guile bug reports to bug-guile@gnu.org.
Changes in 3.0.1 (since 3.0.0):
* New interfaces and functionality
** Export constructor and predicate for '&quit-exception'
The (ice-9 exceptions) module, new in 3.0.0, now exports
'quit-exception?' and 'make-quit-exception', which is consistent with
other exception types.
** (texinfo plain-text) now exports '*line-width*' fluid
The new '*line-width*' fluid allows users to specify the width of a line
for the purposes of line wrapping. See "texinfo plain-text" in the
manual.
* Bug fixes
** 'hash' correctly handles keywords, ports, hash tables, etc.
(<https://bugs.gnu.org/39634>)
It used to be that the 'hash' procedure would return the same value for
all keyword objects, the same value for all hash tables, the same value
for all input ports, etc.
** 'include' no longer rejects relative file names
A bug in 3.0.0 would lead 'include' to error out when passed a relative
file name.
** Reduce GC pressure when using bignums
Guile no longer installs a finalizer on each bignum (large integer) it
creates. This significantly improves speed and memory usage on
applications that make heavy use of bignums, such as the compiler
itself.
** Fix expansion of 'error' calls with a non-constant argument
(<https://bugs.gnu.org/39509>)
Calls to the 'error' primitive with a non-constant argument, as in
(error message), would be incorrectly expanded by the compiler, leading
to non-printable errors ("Error while printing exception").
** Improve source location information for top-level references
(<https://bugs.gnu.org/38388>)
Source location information, as is visible upon "unbound variable"
errors, is now more accurate.
** Web client treats TLS "premature termination" error as EOF
(<https://bugs.gnu.org/39800>)
This allows 'http-request' from (web client) to gracefully handle
servers that terminate connections abruptly after responding to a
"Connection: close" request.
** Fix bug restoring a JIT continuation from the interpreter
** Export C symbols 'scm_sym_lambda', 'scm_sym_quote', etc. again
Those C symbols were inadvertently made private in 3.0.0.
** Fix build on IA64 and on platforms where the stack grows upwards
** Fix JIT compilation on 64-bit Cygwin
** texinfo properly renders @acronym in plain text
See <https://bugs.gnu.org/37846> for details.
** Fix Readline configure check for the sake of libedit
This fixes builds on macOS against the system-provided libedit.
Changes in 3.0.0 (since the stable 2.2 series):
