! 781: non-invertible argument, e.g
! 782: matdet([1+O(3),1+O(3);O(3),O(3)]) --> O(3), not 0

! 1227: 4- the implied input from non-interactive input command (like extern and
! 1228: read) does not go into the GP history (%x) anymore (it never went into
! 1229: readline's). The final output (value of last expression evaluated) of
! 1230: course still does!
! 1231: 5- updated chapter 5 of the User's Manual (removed obsolete information)
! 1232:
! 1233: Added:

! 1235: examples/Inputrc
! 1236: YU 2- support for shared libraries under FreeBSD
! 1237: 3- colors under Emacs
! 1238: 1) emulate exactly the "colors" default after a M-x gp
! 1239: 2) .gp files edited get a special highlighting
! 1240: 4- a flag to default() to get the result under GP
! 1241: 5- overloaded the "." (member) operator to concatenate as strings if LHS is
! 1242: a string

! 1247: Removed:
! 1248: 1- some unused, undocumented functions (allocatemem(), checksqid())
! 1249: made static some other (op_ReIm)
! 1250:
! 1251: ===========================================================================

! 1260: 6- zetainit now aborts cleanly when disc. too big (caused memory fault)
! 1261: 7- exceedingly rare bug in the printing of real numbers (missing decimals)
! 1262: 8- too early rounding in polroots which in rare cases made GP think some
! 1263: error had happened
! 1264: 9- text overflowed the manual pages (and tutorial) on non-A4 paper
! 1265: 10- polred incorrectly assumed that nf arguments were totally real (in a non
! 1266: critical part: that just led to some unnecessary computations)
! 1267: 11- polred(f,2) could try to overwrite universal integer gzero
! 1268: 12- check if we are using GNU as or GNU ld in Configure
! 1269: 13- empty -R argument to $CC when building GP without graphics (==> link
! 1270: failed)
! 1271: 14- bnfinit acts sensibly when fundamental units are too large (before:
! 1272: "overflow in R*R")
! 1273: 15- cleaned up buch2.c (removed ideallllredpart1, removed gerepile in
! 1274: class_group_generators(), not_given now called from getfu)
! 1275: 16- nfgaloisconj(...,2) was unusable (tried an illegal multiplication)
! 1276: 17- is_totally_split was very inefficient (==> nfgaloisconj was very slow)
! 1277: 18- some unimportant typos (gexpo) in polgalois
! 1278: 19- compiling without readline gave a Warning in gp.c (already_hist)
! 1279: 20- some make programs don't like $< (suppressed from doc/Makefile)
! 1280: 21- ellap sometimes assumed wrongly that coeffs of the curve were integers
! 1281: 22- flag 0 and 1 in ellap had been mixed up
! 1282: 23- print an extra \n before an error message if last output did not
! 1283: include it
! 1284: 24- component(any non recursive type) gave a SEGV
! 1285: 25- suminf / prodinf / prodeuler assumed they treated a real expression
! 1286: 26- lindep / algep had problems with numbers having a rational component
! 1287: 27- last significant digits of bessel* and hyperu were wrong (now only the
! 1288: last one is)
! 1289: 28- expi now returns a long as documented (expi(gzero) returned 0 on 64-bit
! 1290: machines!)
! 1291: 29- g++ could not compile libpari.a (casts missing, extraneous extern "C",
! 1292: faulty inline, etc.)
! 1293: 30- cleaned up the enums in gp.h
! 1294: 31- incorrect target veryclean in doc/Makefile
! 1295:
! 1296: Changed:
! 1297: 1- '_' is now valid in GP identifiers
! 1298: 2- removed subsections from table of contents. pages in the manual are now
! 1299: numbered consecutively
! 1300: 3- gexpo now accepts exact 0 arguments (return -HIGHEXPOBIT)
! 1301: gexpo for complex numbers now return max(gexpo(Re), gexpo(Im))
! 1302: 4- parts of lib/gprc.default
! 1303: 5- the second argument of subgrouplist is now optional
! 1304:
! 1305: Removed:
! 1306: 1- buggy label/goto functions
! 1307: 2- (now unused) error messages: labeler, gexpoer2
! 1308: 3- _ as shorthand for conj()
! 1309: 4- (useless, undocumented) function gnormalize
! 1310: 5- some files in the lib directory (functions, gp)
! 1311:
! 1312: Added:
! 1313: 1- some files in the lib directory (README, pari.xbm, xgp)
! 1314:
! 1315: ==============================================================================

! 1317:
! 1318: Fixed:
! 1319: 1- multiple factors forgotten when factoring univariate pols over Z
! 1320: 2- extraneous modifications of the random seed (period of random
! 1321: generator was ridiculously small for some buchxxx functions). Change
! 1322: the bench results (in a non essential way)
! 1323: 3- bad terminal size determination
! 1324: 4- aliases incorrectly killed (possible SEGV)
! 1325: 5- incrementing/decrementing array elements with the (valid) syntax
! 1326: v[i]++ / v[i]-- caused a weird error message
! 1327: 6- subgrouplist() could end up by a SEGV on Linux systems
! 1328: LG 7- on HP-UX, flag -Aa not taken into account in Configure (caused it to
! 1329: fail on has_TIOCGWINSZ.c)
! 1330: LG 8- added a missing #define _INCLUDE_POSIX_SOURCE in galois.c
! 1331: (7 & 8 independently fixed by OV)
! 1332: GN 9- the script examples/cl.gp called vecconcat() instead of concat()
! 1333: GN 10- make install-sta rebuilt gp-sta unnecessarily
! 1334: GN 11- many, many typos in the tutorial
! 1335: 12- tu / fu applied incorrectly to a bnfclassunit
! 1336: 13- bnfclassunit did not output a valid object (matrix whose elements were
! 1337: rows instead of columns)
! 1338: 14- conversion bug from t_QUAD to t_REAL/t_COMPLEX
! 1339: 15- off-by-1 error in the history recovery after an error
! 1340: 16- in fprintferr() (debug messages), embedded %Z did not work correctly
! 1341: 17- rnfequation over Q yielded a SEGV
! 1342: 18- string() in compatibility mode corrupted the stack
! 1343: 19- it is now safe to have colours in prompt and input line under readline
! 1344: 20- default colours restored upon exiting
! 1345: 21- default colors in lib/gprc.default used 0 instead of -1 for "no color"
! 1346: 22- psi and lngamma could give wrong results when the argument was not real
! 1347: 23- the make test-graphic bench was missing a newline
! 1348: 24- Pol(break) gave a SEGV
! 1349: 25- x=1; Pol(1) gave a stupid error message
! 1350: IZ 26- tutorial.tex was unnecessarily rebuilt
! 1351: 27- typos in ggcd (cases nobody will ever access: gcd of a non-reduced
! 1352: LG fraction with an intmod, etc.)
! 1353: LG 28- incorrect handling of integrals of vectors
! 1354: 29- gcd of polynomials with non-exact coeffs gave stupid results (they are
! 1355: still often wrong, since the mathematical notion is rather imprecise)
! 1356: 30- typos in rnfkummer (incorrect flag handling)
! 1357: 31- typo in idealpowprime (negative exponent gave wrong denominator)
! 1358: 32- multiplication t_COMPLEX x t_COMPLEX used 4 mult. instead of 3
! 1359: 33- some modular functions (j, f, f2) rewritten to take advantage of new eta
! 1360: function (trueta)
! 1361:
! 1362: Changed:
! 1363: 1- ?? (gphelp) starts in detex mode (-d) from a console window. tmp files
! 1364: now placed according to the $TMPDIR environment variable (in /tmp by
! 1365: default)
! 1366: 2- /usr/local/lib/pari/data is a better place for the Galois resolvents
! 1367: (which are not included yet in the standard distribution)
! 1368: 3- The example for prompt in gprc.default to discuss escape sequences under
! 1369: readline
! 1370: 4- Configure now starts by searching the toplevel directory for a temporary
! 1371: readline installation
! 1372: 5- The output of default(colors) was confusing. It is a string now
! 1373: 6- third argument of polinterpolate can be arbitrary and is now optional
! 1374: ("x" by default) (it had to be numeric)
! 1375: 7- directory configure renamed config, some of the Makefiles in there as
! 1376: well (to avoid confusion)
! 1377: 8- the low_stack macro to facilitate dynamic stack expansion
! 1378: 9- if, back to GP main loop, the last command was a print1(), output an
! 1379: extra newline. This way the prompt is guaranteed to be anchored on
! 1380: column 1 (suppresses a readline display bug as well)
! 1381: 10- Due to 9, pari.el now supposes the prompt starts in col. 1
! 1382: 11- Better handling of version numbers (LG)
! 1383: 12- decodefactor() renamed to factorback()
! 1384:
! 1385: Removed:

! 1394: IZ 3- OS/2 (+ enough tools...) supported by Configure
! 1395: 4- file examples/Inputrc (example of .inputrc for readline)
! 1396: 5- Weber f1 function implemented
! 1397: 6- Karatsuba multiplication t_REAL x t_REAL (development code, not used by
! 1398: PARI yet). Test it with install if you wish
