[LWASM] +[+] Added || and && as boolean or and boolean and respectively [LWASM] +[+] Added COPY, COPY-, IMP, EXP, TFRP, TFRM, TFRS, TFRR as alternatives to + the TFM instruction variations for compatibility with other assemblers + [LWASM] +[+] Added --6809/-9 switch to cause 6309 instructions to be rejected; also + included --6309/-3 switch to force default allow of 6309 instructions + [LWASM] +[+] ALIGN now takes an optional padding value (ALIGN align,pad) to specify + the byte value that will be used for padding if needed [LWASM] +[+] Added OS9 module target along with the OS9, MOD, and EMOD pseudo ops + to allow building OS9 modules [LWASM] +[+] Added pragma "dollarlocal"/"nodollarlocal" and "dollarnotlocal"/ + "nodollarnotlocal" to control whether $ localizes a symbol [LWASM] +[ ] Fixed a few cosmetic issues with error reporting + +Version 2.4 + +[!] Fixed off by one relocation offest for base page external references + generated by lwasm [LWASM] +[b] Fixed segfault in "extern" pseudo op and allowed a symbol list as the + operand just like "export" [LWASM] +[b] Fixed lack of error when there are extraneous characters at the end + of the operand.
