1200: ===========================================================================
1201: Done for version 2.0.3.alpha (released 13/01/98):
1202:
1203: Fixed:
1204: 1- rare bug in gadd (PADIC + PADIC) which caused one of the arguments
1205: to be overwritten
1206: 2- typos in refcard
1207: 3- galois.c still couldn't compile on the HP (_INCLUDE_POSIX_SOURCE)
1208: 4- introduced in 2.0.2: item 14 used gexpo incorrectly (bnfinit sometimes
1209: did not give units it could have computed)
1210: 5- replaced INFINITY by pariINFINITY in rootpol.c (cancels Warning on OS/2)
1211: 6- on OS/2, target ../gp-$dft in o.xxx/Makefile could not be built
1212: (extraneous $exe_suff)
1213: 7- command line switches so that one can enter them with or without white
1214: space (new function read_arg in gp.c)
1215: 8- setdcolors so that it can't unset disable_colors if we are under emacs
1216: 11- random did not check its argument correctly (random(2^32) was accepted)
1217: 12- b=10; for(a=1,b, b=2) exited immediately, whereas the upper bound is
1218: supposed to be evaluated only once
1219: 13- reorganized the error recovery system (initially because errpile could
1220: cause SEGV on Linux systems)
1221: 14- typo. problems in doc and refcard (interletter spacing in $nfz$...)
1222:
1223: Changed:
1224: 1- Reorganized Makefile.SH: extraction twice as fast
1225: 2- pari.menu and pariemacs.txt rewritten, pari.el updated
1226: 3- expanded the man gp.1 to mention command line switches
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:
1234: 1- better settings for handling the Meta key under readline in
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
1243: 6- .gprc accepts some limited preprocessing directive (#if READL and
1244: #if EMACS (and #ifnot as well)). Updated lib/gprc.default to reflect the
1245: changes
1246:
1247: Removed:
1248: 1- some unused, undocumented functions (allocatemem(), checksqid())
1249: made static some other (op_ReIm)
1250:
1251: ===========================================================================
1252: Done for version 2.0.2.alpha (released 15/12/1997):

1254: Fixed:
1255: 1- typos in the documentation for the random() function
1256: 2- removed an extra -emacs flag in pari.el
1257: 3- decodefactor was incorrectly remembered by whatnow (it's factorback now)
1258: 4- test mode did not prevent all prompt expansion (==> bug in make test)
1259: 5- gphelp stopped abruptly when meeting a cross-referencing macro
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: ==============================================================================
1316: Done for version 2.0.1.alpha (released 29/11/1997):
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:
1386: 1- The (unused, undocumented) Malloc_Procs functions and macros
1387: 2- The (now unused) error message numvarer
1388: 3- some (useless, undocumented) targets in the top Makefile
1389: 4- (useless, undocumented) function polgcd()
1390:
1391: Added:
1392: 1- This file !
1393: 2- new flags -ch, -cb, -cu (colour support) to gphelp (see its header)
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
