+This message announces the availability of Scheme Library release slib3a2.
 
-New in slib3a1:
+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:
 
-  SLIB 3 has undergone major development from SLIB2d6.
+  peanosfc.scm: Peano space filling curve.
 
-  Most noticeable is that SLIB now has a module system with documented
-  semantics and a suite of reflexive tools for deriving reference and
-  module dependencies from library code.  The reflexive tools are
-  designed to support compiler-writer's needs as expressed in
-  discussions arising from comp.lang.scheme in July 2003.
+  logical.scm: (logand, logior, logxor): Take one or more arguments.
+  Refactored to match SRFI-60.
 
-  The module semantics are intended to be compatible both with
-  implementations having module systems and those lacking.  Ivan
-  Shmakov has been striving to integrate SLIB's and Scheme48's module
-  systems.  His efforts and SLIB's reflexive tools have found a great
-  many bugs, some of them present since SLIB's beginnings.
+  All uses of CREATE-ARRAY replaced by MAKE-ARRAY (SRFI-63).
+  All uses of ARRAY-SHAPE replaced with ARRAY-DIMENSIONS (SRFI-63).
 
-  "make install" now creates a "slib" shell script for running various
-  Schemes with SLIB initialization.  Currently supported
-  implementations are gsi (Gambit), Guile, MzScheme, Scheme48, and
-  SCM.
+  * subarray.scm (subarray, array-trim): Rewrote for all arrays being
+  0-based.
 
-  The byte-number module converts between byte-vectors,
-  twos-complement integers, and IEEE floating-point formats -- all in
-  R4RS-compliant Scheme code.  It also converts byte-vectors to a form
-  whose lexicographic ordering matches the encoded number's ordering.
+  * arraymap.scm (array-map!, array-for-each, array-index-map!):
+  Use of ARRAY-DIMENSIONS replaces use of ARRAY-SHAPE.
+  (make-shared-array): converted.
 
-  The correctly ordered byte representations of numbers tie in with
-  SLIB's relational database being extended to include indexed
-  sequential access methods (ISAM).  The Database-interpolation module
-  uses sequential methods to synthesize continuous functions from
-  discrete data tables.
+  * array.scm: Made compatible with SRFI-63.
+  (equal?): Replaces array=?.
 
-    These "continuous databases" are vital to my soon-to-be-released
-    optics program which calculates spectral responses of layered thin
-    films.
+  pnm.scm: Finished implementation; handles 16-bit color.
 
-  The character plotting utility has been improved, and is now
-  complemented by eps-graph, a very flexible graphing library for
-  producing encapsulated-PostScript files.
+  * 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.
 
-  SRFI-2, SRFI-8, and SRFI-9 are added.
+  * ciesia.dat: Added CIE Standard Illuminant A relative spectral
+  power distribution 300 nm - 830 nm at 5 nm intervals.
 
-  Although I have endeavored to support legacy usage, some programs
-  will need modification to work with SLIB 3.  Some issues that I know
-  of are:
+  * ciesid65.dat: Added CIE Standard Illuminant D65 relative
+  spectral power distribution 300 nm - 830 nm at 5 nm intervals.
 
-  * REQUIRE no longer accepts a string as its argument.
-  * The RANDOM module is split into RANDOM and RANDOM-INEXACT.
-  * Some refactoring among TRANSACT, GLOB, and LINE-I/O.
+  * 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.
+
+  * format.scm: Made reentrant; restored.  Call slib:error for errors.
+
+  * dbutil.scm (close-database): Don't lock immutable dbs.
+
+  * transact.scm (word-lock:certificate): Test file's existence
+  before OPEN-FILE.
+
+  vet.scm (vet-slib): Accept file arguments to include in vetting.
+
+  * 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.
