║ Version 3.01 ║
╚══════════════╝
--------------------------------------------------------------------------
25.12.94
--------------------------------------------------------------------------
+++ IDA automatically comments OS/2 DLLs. I didn't have full information
about these DLLs, so I put the comments into text files. You
can modify the comments as you want. The comments reside in *.IDS
files, format of these files is very simple. See DOSCALLS.IDS
Don't forget that IDA itself extracts entry point names from DLL files
if it finds them on the disk.
+++ LX/LE files: if an object has 'Alias 16:16' flag, IDA tries to load it
into low memory (first Mbyte).
*** LX/LE files: IDA didn't display entry points correctly. Fixed.
+++ Z80 for ANTA A80: IDA displays uninitialized bytes as 'equ' directives.
--------------------------------------------------------------------------
21.12.94
--------------------------------------------------------------------------
+++ Now IDA is capable to disassemble several files in one directory.
IDA database file names are changed. Also, IDA packs its database
into one file.
IDA asks file name to disassemble if started without parameters.
Also, IDA asks file name if you specify a file mask.
--------------------------------------------------------------------------
12.12.94
--------------------------------------------------------------------------
+++ Under multitasking systems IDA gives timeslices when idle.
╔══════════════╗
║ Version 3.00 ║
╚══════════════╝
--------------------------------------------------------------------------
08.11.94
--------------------------------------------------------------------------
+++ LE files can be disassembled.
+++ Borland C++ overlay files can be disassembled.
--------------------------------------------------------------------------
07.11.94
--------------------------------------------------------------------------
*** Fixed a bug in 'delete segment' command. It is difficult to explain,
and sometimes occured when a small (<2kb) segment is deleted.
+++ You can get all information from messages window on the disk if you
set environment variable IDALOG:
set idalog=log-filename
*** Fixed a bug: sometimes IDA would prematurely stop to analyse the
program and pretend that the program is fully disassembled.
--------------------------------------------------------------------------
30.10.94
--------------------------------------------------------------------------
*** Fixed a bug in 'indirect jumps' command. It didn't work :(
╔══════════════╗
║ Version 2.09 ║
╚══════════════╝
--------------------------------------------------------------------------
20.09.94
--------------------------------------------------------------------------
+++ IDA has a small built-in text file editor.
+++ many tiny improvements.
--------------------------------------------------------------------------
19.09.94
--------------------------------------------------------------------------
+++ LX files loader is rewritten. Now it should work.
+++ If the user selects an area (using Alt-L) and presses C (convert to
instructions), IDA will analyse the selected area more deeply:
- it will guess indirect table jumps
- it will convert to data zero bytes
- it will convert to instructons all other bytes.
I understand that this is not enough, wait and I'll do more in this
direction.
--------------------------------------------------------------------------
18.09.94
--------------------------------------------------------------------------
+++ Now IDA knows about segment selectors, so you can create segments
beyond 1mb. You create a segment beyond first Mb, it can't accessed
using 16-bit segment & 16-bit offset. So, IDA creates a virtual
selector which points to such segment. Now you can use almost all
32-bit address space, up to 0xFF000000. Addresses higher than this
address are used by IDA for auxillary things.
IDA maintains virtual selectors automatically. When a segment is
created, IDA creates a virtual selector if nessesary, and deletes it
when the segment is being killed. Max number of selectors - 64.
+++ ALT-J (make jumps table) works for 32-bit segments.
--- I recompled IDA to use 386 instruction, so it won't run on 286 anymore.
Sorry.
--------------------------------------------------------------------------
17.09.94
--------------------------------------------------------------------------
+++ Now IDA knows about short and long displacements and marks unnessarily
long instructions with <BAD> marks. For example:
8B840000 mov ax, [si+0]
8B850000 mov ax, [di+0]
will be converted by TASM to
8B04 mov ax, [si]
8B05 mov ax, [di]
so these instructions are <BAD>. Don't forget that <BAD> marks are
turned off by default.
Thanks to Vadim Belman, 2:464/15 who pointed out this fact.
+++ Now you can look at the dump of the program being disassembled.
You simply press Shift-F3 and see a dump of the program bytes
(with ASCII representation). Again press Shift-F3 - and you see normal
view of the program. You can freely use navigation commands in the
dump mode.
--------------------------------------------------------------------------
16.09.94
--------------------------------------------------------------------------
*** Fixed many bugs in disassembling 32-bit mode instructions.
+++ Added 387 processor instructions.
+++ Now IDA knows about 'large' & 'small' keywords for Intel 80x86.
+++ Added 486,Pentium instructions.
+++ Escape character (0x1B) is allowed in ASCII strings.
+++ The instruction
imul r,r,num
is showed as
imul r,num
(asked by Grisha Rusanov)
+++ Two important changes: when you use 'convert to instruction' and
'convert to unexplored' commands and have an area highlighted using
the anchor, all bytes in the highlighted area will be affected by
these commands. For example, if you drop anchor at the start of the
file, go to the end of file and press 'C', IDA will try to convert all
bytes of the program into instructions.
--- -R switch meaning is reversed: it means 'load MS Windows resources'
+++ IDA doesn't try to fix relocations of self-loading MS Windows
programs. It fixes relocations only for the first segment. If I/O error
occur during loading the file, IDA simply warns you about it and
continues to load. The I/O errors may occur because of bad input file
structure.
+++ 2 new commands added (menu Options|Toggle display):
- Display segment part of addresses on/off
- Display <BAD> instructions on/off
Please read about <BAD> instruction in the online help (An instruction
is marked as <BAD> if it is undocumented or it will change its length
after compilation). I didn't change IDA database format number, so
for the old bases they will not be displayed. But you can switch them
on.
*** Fixed a bug: you wasn't able to create segments sized about 64kb or more.
IDA would not move other segments properly.
Thanks to Dimka Kozlov (2:5020/246) for the detailed bug report.
--------------------------------------------------------------------------
01-Sep-94
--------------------------------------------------------------------------
*** Fixed a bug with segment registers emulation.
*** Fixed a bug: you couldn't start "IDA -c file" from the root directory!
*** Fixed a bug with segments.
+++ The NE files loader is rewritten
╔══════════════════╗
║ Version 2.08beta ║
╚══════════════════╝
--------------------------------------------------------------------------
04-Jul-94
--------------------------------------------------------------------------
+++ LX support added. Not complete, namely:
- no support for jump tables (hotkey Alt-J)
- no support for imported modules (IDA doesn't even looks them up)
- problems with segment registers and segment bases
- not all offset & segment selectors supported
- max address avialable to disassebled program - 0x0F000000
Despite of these limitations, I hope that you can try to use it.
Sorry, I have no time for fix them all. Please note that this is
a BETA version. I appreciate any reports about bugs,features, etc.
+++ Now you can change represenation of automatically generated names.
See 'Options' menu.
+++ Several tiny modifications.
--------------------------------------------------------------------------
02-Jul-94
--------------------------------------------------------------------------
*** Fixed a bug with zero length segments in NE format files. IDA would
report silly disk read error and exit, because it couldn't read past
end of file.
Thanks to: Trigub Serge.
*** Fixed a bug with 32-bit form of movsX,cmpsX... etc instructions. If these
instruction have a segment override prefix, IDA would disassemble them
uncorrectly. The same was with 'xlat' instruction.
Thanks to: Trigub Serge.
*** Now IDA knows all about NE format files (I hope ;-). Namely the following
flags/features are recognized now:
- Application types (compatible,incompatible,uses PM API)
- Processor types (by default IDA sets i80286 real)
- Long file names support
- 32-bit segments
- Iterated segments
- Conforming segments
- 286 DPL bits
Among these flags IDA uses only processor type and 32-bit segments flags.
All other flags are simply copied to the output text with appropriate
comments.
Thanks to: Trigub Serge.
╔══════════════╗
║ Version 2.07 ║
╚══════════════╝
--------------------------------------------------------------------------
21-Jun-94
--------------------------------------------------------------------------
*** I fixed a bug which may cause IDA to hang at startup. Sorry :-(
Today I release a new version because of this bug.
+++ Comments are inserted using a text dialog box. You can use a built-in
clipboard.
*** I threw out the 'Shell' command - it doesn't work and makes no sense
because there is little memory.
--------------------------------------------------------------------------
19-Jun-94
--------------------------------------------------------------------------
+++ 'Make Jump Table' command (hotkey Alt-J) is more intelligent now. It
itself tries to find out the table address and size. If you've
specified the table address using 'Make Offset' command, it will
simply present this address. If the table address it not valid, IDA
will beep.
+++ Pascal strings: the string length byte is decimal by default.
+++ 'Enter alternative operand' commands proposes the current representation
as the default string. Many people asked me to do so, it works this way
now.
--------------------------------------------------------------------------
18-Jun-94
--------------------------------------------------------------------------
+++ Support for Intel 860 XP, Intel 860 XR processors is added.
Unfortunately, IDA doesn't support COFF format files - now I'm forced
to implement it... ;-) This is not test!!! I don't have an assembler,
nor a computer, nor even an executable file for these processors!
+++ Now IDA loads IBM PC files into 1000:0 by default.
+++ NE format files: I have only Borland documentation on NE format files.
I didn't find all relocation types in this documentation. For example,
when I tried to disassemble BCC.EXE, there was relocation type 0x4. I
think that bit 2 of the relocation type designates 'additive
relocation' (anology with LX file format). When IDA encounters
relocation type with bit 2 set, it interprets it as additive
relocation. PLEASE, if you have full documentation on NE file format
and I'm wrong with 'additive relocation', let me know! FYI: now IDA
knows about relocation types 0,1,2,3 and bit 2(additive).
--------------------------------------------------------------------------
13-Jun-94
--------------------------------------------------------------------------
+++ Repeatable comments!
All items that refer to the current item will have this comment by
default. This type of comments may be used to describe subroutines,
data items etc., because all calls to the subroutine will have the
repeatable comment.
2 new things:
- MakeRptCmt,ToggleRptCmt added to 'ida.cfg'.
- MakeRptCmt(),RptCmt() functions added to IDC.
Hot keys:
; - make repeatable comment
: - make regular comment
--------------------------------------------------------------------------
05-Jun-94
--------------------------------------------------------------------------
+++ Added a new assembler for the Intel 8080 processor:
- assembler X-M-80 by Leo Sandy (only 6 chars in names)
+++ Added a new assembler for the Z80 processor:
- ASxxxx by Alan R. Baldwin v1.5
(this assembler produces incorrect code for SUB instruction)
- assembler X-M-80 by Leo Sandy (only 6 chars in names)
- A80 by ANTA electronics
(as far as I know, this assembler is used to program Automatic
Caller Identification devices in Russia)
+++ Added a new assembler for the HD64180 processor:
- ASxxxx by Alan R. Baldwin v1.5
(this assembler produces incorrect code for SUB instruction)
*** Work with undocumented registers of the Z80 processor like xl,etc.
is changed.
+++ 3 changes in IBM PC analyser:
- Now IDA knows about AAD,AAM <n> instructions where n != 10
It displays them as data bytes.
- Now IDA distinguishes jmp and jmp short.
- Now IDA knows about the tiny and long OR,XOR,AND,CMP,ADD,ADC,SUB,SBB
instructions and displayes the large instructions that may be
coded as tiny instructions as data bytes, because TASM will produce
tiny code. Now we can get output text that produces exactly the
same code as the input code.
--------------------------------------------------------------------------
04-Jun-94
--------------------------------------------------------------------------
+++ I forgot to describe several changes, they exist in v2.06:
- 'MakeVariable' command works as a trigger. When you mark a byte
as variable, all xrefs to it will disappear and will be
recalculated. Don't be afraid.
- If IDA v2.06 detects IDA database from version v2.05 it will
ask your permission to convert to into newer format.
- You can select any processor type within the current processors
line.
- There was a small bug in PC emulator: IDA thought that 'int N'
command passes execution to 0:4*N. Fixed.
+++ File Name Dialog box added. Now it is possible to browse directories
and search for the file names.
╔══════════════╗
║ Version 2.06 ║
╚══════════════╝
--------------------------------------------------------------------------
31-May-94
--------------------------------------------------------------------------
*** Fixed a bug in bTree: if memory is not enough, it could display a bad
error message or even could crash.
+++ Intel 8080/8085 support is enhanced. Now IDA knows about various
assemblers and can generate the output text for them. For the moment IDA
knows the following 8085 assemblers:
- PseudoSam by PseudoCode
- Table Driven Assembler (TASM) by Speech Technology Inc.
- Cross-16 by Universal Cross-Assemblers
(doesn't know about 'cz' instruction)
- A80 by ANTA electronics
+++ Z80 support (including undocumented instructions):
- Avocet Macro Preprocessor v1.0 by Avocet Systems, Inc.
(doesn't like long lines >80 in the input file, IDA doesn't check this)
- PseudoSam by PseudoCode
(doesn't understand add ix,ix; uses only 8 chars in the names!!)
- Table Driven Assembler (TASM) by Speech Technology Inc.
(doesn't understand 'rst 0', needs 'rst 00h',has bugs, see help)
- Cross-16 by Universal Cross-Assemblers
(doesn't understand 'set' instruction,has bugs)
+++ Binary line prefixes are added. They are displayed by default.
The binary line prefix is:
seg000:1234 55 push bp
^^^^^^^
i.e. assembled code. You can show/hide them using
{Options|Toggle display} menu. IDA shows 8 bytes per line, you can't
change this.
--------------------------------------------------------------------------
15-May-94
--------------------------------------------------------------------------
+++ Snow check is disabled in Tvision. Faster several times!!! Tvision is
shipped with snow detection by default :-(((. Today I learned about it
and disabled it. Blazing speed!!! Also, several bugs in TVision are
fixed (I don't think that they affected IDA performance).
+++ When you try to open a new IDAView window, sometimes IDA hangs. I
inserted a debugging code into IDA. If you see that IDA hangs, you may
try to push Alt-Space key, a coredump will be created.
╔══════════════╗
║ Version 2.05 ║
╚══════════════╝
--------------------------------------------------------------------------
16-Mar-94
--------------------------------------------------------------------------
+++ When the user types in the string in the list viewer, (like in the
Norton Commander using Alt-keys), IDA tries to find the matching line
not only below the current position, but in the whole list. The same
is when the user searches for the substring (using '?').
+++ 'Open names window' command added. See 'View' submenu.
+++ Histories for different types of input are separated from each other.
+++ You can scroll horizontally list viewer windows.
+++ In the list viewers the 'refresh window' command (Ctrl-U) is not
needed because IDA automatically refreshes a list viewer window when
you select it.
--------------------------------------------------------------------------
14-Mar-94
--------------------------------------------------------------------------
*** Several bugs fixeds, many small changes
*** Alt-R (any offset) command works as before now (proposes a list of
segments you can select from).
--------------------------------------------------------------------------
11-Mar-94
--------------------------------------------------------------------------
*** I've got tired of the bugs in the Tvision int 21h handler. Another bug
is fixed there.
--------------------------------------------------------------------------
06-Mar-94
--------------------------------------------------------------------------
+++ New: Produce ASM file, Produce LST file commands.
+++ Indirect jumps table size is proposed by IDA. It proposes a maximal
possible value. Be careful!
+++ MS Windows entry points are searched and marked as instructions at the
loading time.
╔══════════════╗
║ Version 2.04 ║
╚══════════════╝
--------------------------------------------------------------------------
05-Mar-94
--------------------------------------------------------------------------
+++ Now you can open windows with program segmentation or segment
registers. See 'View' submenu for details.
--------------------------------------------------------------------------
03-Mar-94
--------------------------------------------------------------------------
*** Fixed a bug with help system in the menus: if the user presses F1, he
can't escape help system till he quits menuing system.
--------------------------------------------------------------------------
02-Mar-94
--------------------------------------------------------------------------
*** Fixed a bug in error messages display. IDA didn't report memory
allocation errors properly: it reported any other error. IDA requires
about 500K memory!
*** Fixed a bug: very small files (less than MS DOS exe file header)
couldn't be disassembled.
╔══════════════╗
║ Version 2.03 ║
╚══════════════╝
--------------------------------------------------------------------------
26-Feb-94
--------------------------------------------------------------------------
*** Fixed a bug in plain exe-file loading. The previous version of IDA was
not able to load plain exe-files.
+++ map2idc.exe utility is enchanced.
*** References beyond segment boundaries are displayed correctly now.
╔══════════════╗
║ Version 2.02 ║
╚══════════════╝
--------------------------------------------------------------------------
25-Feb-94
--------------------------------------------------------------------------
*** Fixed a bug in IDC engine
+++ 4 new switches added:
-R - don't load MS Windows resources.
IDA doesn't analyse the resources (see file 'resource.idc'
for the example), so you may want to skip resources.
-W### specify MS Windows directory.
Default Windows directory is c:\windows. If you have installed
Windows in another directory, specify this switch. IDA will
lookup DLLs in this directory.
-x - don't create initial segmentation
This is useful if you want to upgrade your database using
an IDC file created by 'Unload' command. The 'Unload'
command is used when you want to switch to a new version
of IDA. Usually each new version of IDA has its own database
format. To create a new format database, you need:
- to issue the 'Unload' command for the old
database (using old version of IDA). You will
receive an IDC file containing all information
from your old database.
- to reload your database using new IDA with switch
-x.
- to compile and execute the IDC file with command
'Execute IDC file' (usually F2)
IDA with -x switch doesn't create segmentation, thus the
loading goes faster. This is the only benefit of this switch.
This switch doesn't affect NE format files.
-n - don't load New Executable Format.
Even if MS Windows executable found, it will be loaded as
an ordinary EXE file.
+++ 2 IDC example files are created:
kernel.idc
How to insert user-defined comments for DLL entry points
You can add your comments too.
resource.idc
How to analyse MW Windows resources using IDC.
+++ Now IDA regularly checks disk space and if it is less than 100k,
it warns the user. It is not recommended to work with IDA if the disk
space is low!
*** Fixed 2 bugs in TVision (help subsystem)
+++ Help index created. Press Shift-F1 to get help index.
--------------------------------------------------------------------------
24-Feb-94
--------------------------------------------------------------------------
+++ New Executable Format files can be disassembled now. IDA displays
resources as byte arrays for the moment. In order to give symbolic
names to the external references IDA looks for the MS Windows files
in the:
- current directory
- C:\WINDOWS
- C:\WINDOWS\SYSTEM
In the future there will be a way to specify Windows directory.
+++ Display of offsets is changed. Now IDA tries to display an offset even
if the target address is beyond segment bounds. The 'EOS_...' symbols
are not generated anymore.
+++ There was a limit on the number of contigious chunks in the program.
You was able to create up to 51 distinct, non adjacent segments. Now
you can create up to ~ 170 such segments.
--- Register values are not saved into the disk anymore.
As experience showed, this is not so useful and wastes disk space.
+++ Now IDA leaves a file names 'ida.idl' after its work. You can simply
delete this file, it is left for debugging purposes. It contains the
compiled form of IDC programs.
╔══════════════╗
║ Version 2.01 ║
╚══════════════╝
--------------------------------------------------------------------------
16-Feb-94
--------------------------------------------------------------------------
+++ Offset bases are kept as 32-bit effective addresses. This allows to
have offsets from any point of the program. For example, you can
create an expression:
offset A - (offset B)
specifying 'B' as a base the offset. The 'offset by any base' command
is changed. Now it asks to enter an address.
+++ Many small changes and enchancements.
+++ 'Unload' command added. This command creates an IDC file. The IDC file
can be executed at any time later to recreate IDA database from the
scratch. This command provides a way to upgrade to newer IDA versions
when IDA database format is changed. Another point is that this file
can be used as a safety measure (from IDA database crashes).
+++ The 'Execute IDC command' is splitted into 2 commands:
- execute an IDC command
- execute an IDC file (that means to execute 'main' function)
--------------------------------------------------------------------------
12-Feb-94
--------------------------------------------------------------------------
+++ IDC language is completely rewritten. Now there are 2 steps:
compilation and execution. All C execution flow control structures are
supported, except the following:
- labels
- switch statement
See file 'idc.doc' for details.
╔════════════════════╗
║ Version 2.01 beta0 ║
╚════════════════════╝
--------------------------------------------------------------------------
25-Jan-94
--------------------------------------------------------------------------
+++ New commands:
- delete a segment
- change segment bounds
--------------------------------------------------------------------------
09-Jan-94
--------------------------------------------------------------------------
*** Fixed a bug in TurboVision. It appeared only on machines with 1 floppy
drive. In this case TurboVision tries to check that the floppy drive
emulates the needed disk (A for real,B for fantom). The code that
implements this check is lousy. I completely rewrote this code.
*** Bug fixed: If the user leaves IDA when the cursor is at the line
number 30 (for example) and next time he runs IDA with 25 lines on the
screen, the cursor is not on the screen. (sometimes IDA hangs)
╔═══════════════════╗
║ Version 2.0 ║
╚═══════════════════╝
--------------------------------------------------------------------------
07-Jan-94
--------------------------------------------------------------------------
+++ 'Forms' are created. They allow the user to enter multiply inputs
simultaneously. The user interface will be rewritten to use the forms.
*** Small bug is fixed with names. It existed only in ida2.0 beta2.
references to the second (or third...) bytes of an item would display
incorrectly.
--------------------------------------------------------------------------
03-Jan-94
--------------------------------------------------------------------------
*** Fixed a tiny bug in void marks. This bug exists only in IDA2.0 beta2.
+++ Now IDA checks all near jumps and calls that they are within one
segment. If not, it tries to move the segment.
+++ 'MakeArray' command proposes maximal size of array considering file
segmentation.
+++ Now it is impossible to define an item (instruction or data) which
crosses segment boundaries.
+++ By default line prefixes are shown.
+++ Extended/expanded memory swapping options are moved into configuration
file. Only overlayed code will be swapped. By default IDA will use 256
kb ext and 256 kb exp memory. However, IDA needs only ~200kb memory
for swapping.
*** Fixed a bug in auto-analysis toggler. It was impossible to turn the
analysis off.
+++ IDA doesn't disassemble instructions after overlay interrupt (3Fh).
+++ 'Repaint' command is added. See menu File... IDA automatically
repaints the desktop after database repairing.
+++ Now 'Shell' command works again. (it invokes DOS shell temporaryly)
Not so much memory is left (~60Kb).
+++ Help subsystem improved: F5-zoom help window, Backspace - previous
help screen.
--------------------------------------------------------------------------
29-Dec-93
--------------------------------------------------------------------------
*** Fixed a tiny bug in automatic analysis queue.
+++ Now IDA searches for 'Borland C++ - Copyright 1991 Borland Intl.' in
the loaded file, and if finds, it assumes this segment to be default
data segment. It sets default DS value for all segments to point to
this segment.
+++ Memory allocation is changed: now bTree gets less memory.
+++ If segment register doesn't change its value at the change point, it
is not displayed in the 'segment registers list'.
+++ 'set default segment register value' command added. See menu
Edit|Registers...
--------------------------------------------------------------------------
26-Dec-93
--------------------------------------------------------------------------
*** Fixed a bug in keyboard macros. It was impossible to redefine a macro.
+++ Each segment has default segment register values. Generally, segment
definitions are cleaned, now IDA supports all segment features. (at
least from intel specification of SEGDEF's):
- alignment
- combination
- use16/use32
- Phar Lap extensions (are not displayed, for the future)
- class names
- overlay names (are not displayed, can't be changed yet)
Class names are not deleted. Once defined, they exist forever, even if
the user chooses another class name for a segment. Segment names are
checked to be a unique name in the program. Phar Lap extensions and
overlay names are defined; the intention is to display them if OBJ
file is being disassembled.
╔═══════════════════╗
║ Version 2.0 beta2 ║
╚═══════════════════╝
--------------------------------------------------------------------------
19-Dec-93
--------------------------------------------------------------------------
+++ Huge arrays (more than 64K) can be displayed fast.
+++ File core.ida is merged into file 1.ida. It works faster and we have
more memory.
+++ 'Toggle line prefixes display' command added. It shows/hides line
prefixes. Now 'GenAsm' command creates a file with or without line
prefixes depending on this switch value. By default, prefixes are not
shown.
+++ Now it is possible to view many files of umlimited size using
'ViewFile' command.
--------------------------------------------------------------------------
18-Dec-93
--------------------------------------------------------------------------
*** Fixed a bug in keyboard macros.
+++ File 1.ida (feature flags) can keep features of non-contigious
addresses.
+++ IDC command "view" can be accessed from main IDA menu. And this
command adds a new window to the screen, allowing the user to continue
his work.
+++ Immediate arguments of instructions can be displayed as character
constants. Before it was possible only for special cases of arguments.
--------------------------------------------------------------------------
12-Dec-93
--------------------------------------------------------------------------
+++ Data values can be displayed as character constants. For example,
dw 41h,42h,43h
may be converted (using 'MakeChar' command) to
dw 'A','B','C'
+++ Segment registers use less disk space now. This should lead to the
smaller IDA database (file 0.ida).
*** There were some problems with processor types. Now this is fixed.
--------------------------------------------------------------------------
11-Dec-93
--------------------------------------------------------------------------
*** If during IDA database compression we run out of the disk space, the
disk compression program would fall into an infinite loop, printing
error messages on the screen. This is fixed.
+++ Virtual Arrays format is changed. Now they can have multiply chunks of
contigious subarrays. This will be used for virtual segments and
structures. They will come soon!
*** DOS critical errors would lead to program hanging if the user selects
to retry. Now this is fixed. The problem was with Tscreen module of
Turbo Vision. This module can't reside in the overlay because it is
called from the DOS error handler.
--------------------------------------------------------------------------
06-Dec-93

*** Fixed a bug in bTree. This bug leaded to the database corruption with
fatal error message. Nobody reported me about it, I hope that nobody
has encountered it. I've found it after modifications from 04.12.93.

+++ Some changes to the database format were made. Now IDA analyses code
sequ beta0
didn't create segments properly. Now it works.
+++ Now IDA recognizes and marks some typical byte sequences as
instructions.

+++ Binary search input line string format is changed.
Now you can specify any sequence of bytes including zeroes etc.
Examples:
0xD, 0xa, "Test" - will search for the CR,LF
followed by the word "Test".
7 8 9 10 - will search for numbers
027 - will search for ESC code.

*** Btree class opens files in readonly mode if Btree will not change.
(the previous version of Btree did it, but I was forced to modify the
new one for this). I need this for IDA.INT file.

18-Dec-92
--------------------------------------------------------------------------
*** New Btree (in C++,written by Pol Rousnak) is used. Althrough I tried
to test it myself, bugs are very possible. Again, version 1.8 is
incompatible with previous versions. For future versions, I will
maintain compatibility (or will write a special utility to upgrade
your databases). Again, IDA is much faster now.
