It is also upper compatible to srfi-9 records. o More support for multithreaded applications: Thread-safe queue is added to util.queue, and thread-pool feature is provided by the new module control.thread-pool. Continuations can be passed between threads. o Partial continuations. o Enhanced Windows support. o New module: crypt.bcrypt: A module for Blowfish password hashing. o New module: srfi-98: portable environment variable lookup support. o New module: gauche.mop.propagate: Making object composition simpler. o New module: rfc.json: JSON parsing and construction. + Changes o The directory structure for Gauche installation has changed so that we can keep binary compatibility for the extension modules throughout 0.9.x releases. o Now it is an error to pass a keyword argument that isn't expected by the callee. It used to be a warning. o Regular expression re{,M} now means the same as re{0,M}, which is compatible to Oniguruma. + Improvements o The compiler and the runtime got optimized more. The compiler now knows more about built-in procedures, and tries compile-time constant folding and/or inlining more aggressively. For example, sxml.ssax can parse XML document a lot faster. o ^ can be used in place of lambda, allowing more concise code. There's also convenience macros ^a, ^b, ... ^z and ^_ as abbreviations of lambda (a) etc. o ~ is added for universal accessing operator. (~ x y) is the same as (ref x y), and (~ x y z) is the same as (ref (ref x y) z), and so on. It can be used with generalized setter, e.g. (set! (~ array i) x). o define-syntax, let-syntax, and letrec-syntax are enhanced so that they can take a general expression in rhs, as far as it yields a syntactic transformer. o gauche.process: I/O redirection handling in run-process becomes more flexible. o rfc.http module now supports https connection (unix platforms only). Currently it relies on an external program (stunnel). o A new procedure current-load-path allows the program to know the file name it is being loaded from. o A new procedure .$ is introduced as an alternative name of compose. o Regular expressions now got read-write invariance. Some internal regexp routines are made public, giving users an easy way to construct and analyze regexp programatically. o rfc.822: New procedure: rfc822-date->date. o file.util: The procedure temporary-directory now became a parameter so that you can switch it when necessary. The default value is taken from (sys-tmpdir), which determines temporary directory in the recommended way of the platform; esp., it works on Windows native platforms. home-directory works on Windows, too. Procedures null-device and console-device are added to make it easier to write portable script across Unix and Windows platforms. o util.queue: New proceduers: any-in-queue, every-in-queue. o gauche.parseopt: When let-args encounters a command-line option that doesn't match any spec, it now raises a condition of type instead of . The application can capture the condition to handle invalid command-line arguments. o gauche.uvector: New procedure uvector-size to obtain number of octets actually to be written out when the given uvector is written out by write-block. o dbm: A new procedure dbm-type->class allows an application to load appropriate dbm implementation at runtime. Utility scripts dbm/dump and dbm/restore are provided for easier backup and migration. o Procedure slot-pop! is added for the consistency with other *-push!/pop! API pairs. o When ref is used for object slot access, it can take default value in case the slot is unbound. o Made (set! (ref list k) value) work. o New procedures delete-keywords, delete-keywords!, tree-map-map, tree-map-for-each. o unwind-protect allows multiple handlers, as in CL. o sqrt now returns an exact number if the argument is exact and the result can be computed exactly. Also, R6RS's exact-integer-sqrt is added. o gauche.parameter: Parameters can be used with generalized set!. o The default-endian parameter is moved from binary.io module to the core, so that this parameter controls default endian of binary I/O in general. For example, read-block! and write-block of the gauche.uvector module now uses the value of this parameter as the default. A new procedure native-endian is added to retrieve the platform's native endianness. o More R6RS procedures: inexact, exact, real-valued?, rational-valued?, integer-valued?, div, mod, div0, mod0.
