20201124-1455 -- minor patch adding `BRK` as a shortcut of `db $ED,$FF` following an idea from Norecess and Roudoudou.
20210114-1255 -- minor patch allowing redefining labels from the command line, f.e. `-DVAR=0 -DVAR=1` first defines VAR as 0, then redefines it as 1.
20210421-2555 -- minor patch adding SL1 and EXA as synonyms of SLL and EX AF,AF' (cfr. RASM).

20220806-2555 -- minor patch adding the new error "ENDM without MACRO" and forbidding negative shift counts, i.e. `LD A,1>>-1` raises a syntax error.
20211030-1345 -- minor patch adding SJASM-compatible shortcuts `LD BC/DE/HL,(IX/IY+NN)` (i.e. `LD BC,(IX+5)` becomes `LD C,(IX+5)` + `LD B,(IX+6)`), `LD (IX/IY+NN),BC/DE/HL` (i.e. `LD (IX+5),BC` becomes `LD (IX+5),C` + `LD (IX+6),B`), `RL/RR/SLA/SRA/SLL/SRL BC/DE/HL` (i.e. `SLA BC` generates `SLA C` + `RL B` and `SRA BC` generates `SRA B` + `RR C`) and "SUB HL,BC/DE/HL" (i.e. `SUB HL,BC` generates `CP A` + `SBC HL,BC`).

20230120-0955 -- minor patch fixing a bug in `RR/SRA/SRL BC/DE/HL`: the second half operated with B, D or H instead of C, E or L.
20221020-2555 -- minor patch adding `ELIF EXPRESSION` as a shortcut of `ELSE /// IF EXPRESSION /// ... /// ENDIF`, plus the matching error `ELIF without IF`.

20230626-2555 -- minor patch adding `DEFC "STRING"[,"STRING" ...]` that toggles the highest bit in the last character of each string, i.e. `DEFC "DISC","TAPE"` is equivalent to `DEFB "DIS","C"+128,"TAP","E"+128`.

20240224 -- minor patch removing several warnings and reducing the version string to the date alone; the time had been meaningless for a very long while.
20231103-2555 -- minor patch making the AS80-compatible mode (command line parameter `-$`) reject non-AS80 pseudo instructions ELIF and INCBIN and R800-exclusive opcodes MULUB and MULUW.
