+This message announces the availability of Scheme Library release slib3a3.
 
-It has been too long since the last release.  Many bugs have been
-fixed; and support for several implementations (especially Guile,
-Scheme48) has been significantly improved.  New in slib3a2:
-
-  peanosfc.scm: Peano space filling curve.
-
-  logical.scm: (logand, logior, logxor): Take one or more arguments.
-  Refactored to match SRFI-60.
-
-  All uses of CREATE-ARRAY replaced by MAKE-ARRAY (SRFI-63).
-  All uses of ARRAY-SHAPE replaced with ARRAY-DIMENSIONS (SRFI-63).
-
-  * subarray.scm (subarray, array-trim): Rewrote for all arrays being
-  0-based.
-
-  * arraymap.scm (array-map!, array-for-each, array-index-map!):
-  Use of ARRAY-DIMENSIONS replaces use of ARRAY-SHAPE.
-  (make-shared-array): converted.
-
-  * array.scm: Made compatible with SRFI-63.
-  (equal?): Replaces array=?.
-
-  pnm.scm: Finished implementation; handles 16-bit color.
-
-  * colorspc.scm (read-normalized-illuminant, illuminant-map)
-  (illuminant-map->XYZ): Added.
-  (wavelength->CIEXYZ, XYZ:normalize, XYZ:normalize-colors)
-  (temperature->CIEXYZ, spectrum->CIEXYZ, wavelength->CIEXYZ):
-  Removed; use chromaticity functions instead.
-  (read-cie-illuminant): Added.
-
-  * ciesia.dat: Added CIE Standard Illuminant A relative spectral
-  power distribution 300 nm - 830 nm at 5 nm intervals.
-
-  * ciesid65.dat: Added CIE Standard Illuminant D65 relative
-  spectral power distribution 300 nm - 830 nm at 5 nm intervals.
-
-  * daylight.scm (sunlight-chromaticity): Replaces sunlight-CIEXYZ.
-
-  * solid.scm (scene:sun, scene:overcast): Use chromaticity to
-  normalize XYZ values.
-  (solid:polyline): Added.
-  (solid:cylinder): Negative radius for invisible side.
+SLIB is a portable Scheme library providing compatibiliy and utility
+functions for all standard Scheme implementations.
 
-  * format.scm: Made reentrant; restored.  Call slib:error for errors.
+SLIB supports the Bigloo, Chez, DrScheme, ELK, GAMBIT, Jscheme,
+MacScheme, MITScheme, PocketScheme, RScheme, Scheme->C, Scheme48, SCM,
+SCSH, T3.1, UMB-Scheme, and VSCM implementations.
 
-  * dbutil.scm (close-database): Don't lock immutable dbs.
+SLIB is free software.  It has a Permissive-Non-Warranty license
+(http://www.swiss.ai.mit.edu/~jaffer/SLIB_COPYING.txt).
 
-  * transact.scm (word-lock:certificate): Test file's existence
-  before OPEN-FILE.
+Documentation and distributions in several formats are linked from
+SLIB's home page:
 
-  vet.scm (vet-slib): Accept file arguments to include in vetting.
+             http://swissnet.ai.mit.edu/~jaffer/SLIB.html
 
-  * vscm.init, umbscheme.init, scsh.init, macscheme.init,
-  guile.init, gambit.init, elk.init, chez.init, STk.init,
-  RScheme.init, Template.scm, pscheme.init, t3.init, scheme48.init,
-  scheme2c.init, s48-0_57.init, mitscheme.init, bigloo.init
-  (*features*): Regularized order and content.
+Links to distributions of SLIB and related softwares are at the end of
+this message.

+slib3a3 news:
+
+Multi-dimensional linear interpolation and resampling of arrays are
+added.  Case-folding of symbols is removed from SLIB.  It should work
+with implementations which are case-sensitive when reading symbols.
+
+  * grapheps.scm (graph:plot): Plot multiple traces from array.
+  (functions->array): Generalizes graph:plot-function.
+
+  * root.scm (integer-sqrt): Changed to algorithm attributed to
+  Bradley Lucier by Steve VanDevender.
+  * slib.texi (Root Finding): integer-sqrt changed to floor of sqrt.
+
+  * linterp.scm (interpolate-array-ref, resample-array!): Added.
+
+  * bytenumb.scm (bytes->ieee-float, bytes->ieee-double)
+  (ieee-float->bytes, ieee-double->bytes): Fixed for -0.0.
+  * bytenumb.scm (ieee-float->bytes, ieee-double->bytes): Handle 0/0
+  in srfi-70 arithmetic.
+
+  * guile.init (slib:load, slib:load-from-path): Adapted patch from
+  Thomas Bushnell BSG for loading into SLIB module.
+  * guile.init (home-vicinity): Check for getenv first.
+  (*features*): Fixed array, system, etc.
+  (system->line): Fixed return status (thanks to Rob Browning).
+  (guile:wrap-case-insensitive): Removed; sources now case clean.
+  * guile.init (system->line): Added features line-i/o and hash.
+  (implementation-vicinity): Fixed to parent directory of ice-9.
+  * guile.init (sub-vicinity): Downcased software-type symbols.
+
+  * dirs.scm, transact.scm, batch.scm, prec.scm,
+  Template.scm, *.init: Downcased all software-type symbols.
+  * require.scm, mklibcat.scm, mkclrnam.scm, alistab.scm, Makefile:
+  Downcased *slib-version* symbol.
+
+  * top-refs.scm (top-refs:expression): Check for lists before
+  walking CASE and COND clauses (srfi-61.scm macro broke it).
+
+  * http-cgi.scm (query-alist->parameter-list): Fixed order of nary
+  fields.
+  * http-cgi.scm (http:status-line): Changed to HTTP-1.0; works
+  better in MS-Windows.
+  * db2html.scm (command:make-editable-table): Boolean "arity".
+
+  * peanosfc.scm (peano-coordinates->natural)
+  (natural->peano-coordinates): Non-negative versions.
+  * phil-spc.scm (hilbert-coordinates->integer): nbits calculation
+  was missing (incorrectly used rank).
+  (bitwise-laminate, bitwise-delaminate): Removed unused functions.
+
+  * slib.texi (SRFI): Added table mapping SRFI to feature.
+  (Scheme Syntax Extension Packages): Moved most SRFIs here.
+  * srfi.scm: Removed comments about copyright.
+  * mklibcat.scm (and-let*, receive, define-record-type)
+  (guarded-cond-clause): Added aliases for srfi-2, srfi-8, srfi-9,
+  and srfi-61.
+  * Makefile (srfiles): Most srfi-* moved from txiscms.
+  (srfiles): Added srfi-61.
+
+  * slib.spec: Updated from RedHat version from Jindrich Novy.
+  * slib.spec (%post): Commented out install-info.
+  * slib.spec (install): Make slib executable.
+  * slib.spec: Fixed for rpmbuild version 4.3.1
