Objavljen je izdanak SBCL 2.3.11 (Steel Bank Common Lisp), slobodne implementacije programskog jezika Common Lisp. Kod projekta napisan je na jezicima Common Lisp i C, te se distribuira pod BSD licencom. U novom izdanju: <\/p>\n

Mali nesuglasja:\n
\n
Tokovi s parametrom external-format, koji je definiran pomo\u0107u \u00ab:REPLACEMENT\u00bb, primjenjivat \u0107e podatke za zamjenu informacija jednom u toku, \u0161to dovodi do gre\u0161aka u dekodiranju (ne kao u nekim slu\u010dajevima, jednom za svaki niz bajtova, od kojih nijedan nije va\u017ee\u0107a po\u010detna pozicija simbola za taj external-format).\n
Definitori external-format pri kori\u0161tenju nepodr\u017eanih ili neprepoznatih varijanti sada \u0107e signalizirati gre\u0161ku. <\/ul>\n
Pobolj\u0161anja:\n
\n
Tijekom usmjeravanja generi\u010dkih funkcija, koje koriste standardnu ili kratku metodu kombiniranja, kada nema glavnih primjenjivih metoda, sustav \u0107e pozvati generi\u010dku funkciju SB-PCL:NO-PRIMARY-METHOD, \u010dije je standardno pona\u0161anje signaliziranje gre\u0161ke. Korisnici mogu definirati metode za ovu generi\u010dku funkciju.\n
Vanjski formati sada podr\u017eavaju varijante nove linije za jedno-bajtne i utf-8 kodiranja.\n
Gre\u0161ke o kodiranju i dekodiranju simbola, koje signaliziraju funkcije tokova ili okteta, sada podr\u017eavaju USE-VALUE ponovno pokretanje za rukovatelje koji pru\u017eaju zamjene za unos ili izlaz.\n
READ-SEQUENCE i WRITE-SEQUENCE podr\u017eavaju sekvence koje definira korisnik; standardna implementacija obra\u0111uje element po element, \u010ditaju\u0107i ili bilje\u017ee\u0107i jedan bajt ili simbol iz\/u tok prema tome. <\/ul>\n
Optimizacije:\n
\n
Vanjski formati s ':REPLACEMENT' vi\u0161e ne povezuju rukovatelje za gre\u0161ke funkcija konverzije, \u0161to bi trebalo smanjiti broj cons-operacija i pove\u0107ati performanse.\n
Ako ':EXTERNAL-FORMAT' djeluje kao argument za STRING-TO-OCTETS ili OCTETS-TO-STRING i je konstanta tijekom kompajliranja, vanjski format se razrje\u0161ava tijekom u\u010ditavanja, a ne prilikom svakog poziva.\n
Kompajler mo\u017ee ograni\u010diti tipove argumenata za neke funkcije na temelju izvedenog ili podrazumijevanog tipa vrijednosti koju vra\u0107a ta funkcija.\n
Kompajler smanjuje broj suvi\u0161nih provjera tipova u funkcijama poput ASSOC i GETF. <\/ul>\n
Ispravke gre\u0161aka:\n
\n
OCTETS-TO-STRING is correctly signaling or applying substitutions when using single-byte external formats for less common encodings (e.g., iso-8859-3), rather than taking bits from the NIL address and converting those bits into characters.\n
FILE-STRING-LENGTH now returns NIL if the input values are not encoded in the external stream format.\n
Table multi-byte external formats (EUC-JP, Shift-JIS, GBK) now account for the replacement character (in the external format or via restarts) when encoding to octets.\n
Converting from octets using external formats UCS-2, UCS-4, and UTF-32 no longer reads the end of the octet array with a non-integer number of two- or four-byte units.\n
Converting from octets using external formats UCS-2, UCS-4, and UTF-32 now returns a simple string as required by the definition of OCTETS-TO-STRING.\n
Applying an incorrect external format argument for OPEN or WITH-OPEN-FILE (or internal MAKE-FD-STREAM) no longer leads to a file descriptor leak.\n
SB-ROTATE-BYTE specifies BYTE specifications out of the allowed range before executing cons of very large integers for use in masks and shifts.\n
Fixing type output when compiling SB-ROTATE-BYTE forms with a non-zero POSITION in the byte definition.\n
Fixing several assembler bugs when compiling MAKE-ARRAY, MAKE-STRING, and others with a large constant size.\n
Fixing an internal error when compiling (SETF-SBIT) with a large constant index.\n
Fixing an internal compiler error for a lambda function with an incorrect parameter list in LABELS.\n
Fixing an internal compiler error when compiling some infinitely-recursive forms in LABELS.\n
Fixing an internal compiler error when attempting to embed a jump to an already deleted label.\n
FILL-POINTER should never be negative. <\/ul>\n<\/ul>\n
