Version 1.0.0
=============
MDB Tools 1.0 includes a number of new features compared to the 0.9 series. The
most significant change is that mdbtools.h is now generated at build time, and
its internal HAVE_ macros have been removed. This means that it is now safe for
clients to compile against mdbtools.h without needing to provide the same
HAVE_ICONV and HAVE_GLIB flags that were present when the library was first
compiled. For most users, MDB Tools 1.0 will be ABI and API compatible with the
0.9 series but see the notes in the "Install" section below.
The SQL engine has two new operators: ILIKE (case-insensitive pattern matching)
and <> (not equals).

Build:
* Generate platform-specific `mdbtools.h` at configure-time #316
* Ensure compiler supports thread-local storage

* New `--disable-iconv` configure option (falls back to `wcstombs` where possible)
* Fix a build error when `./configure` detected iconv, but thought it was not working
* Generating the configure script now requires autoconf 2.64 or later

Version 0.9.2
=============
MDB Tools 0.9.2 is a security and bug-fix release. Due to a number of memory
errors uncovered by OSS-Fuzz, all users who use MDB Tools to read data from
untrusted sources are encouraged to upgrade to 0.9.2 as soon as possible.
The release also includes some minor improvements and behavior changes,
described below.
libmdb:
* Fix infinite loop with malformed input (oss-fuzz/28789)

* `mdb_col_to_string` now prints a warning and returns `""` for any unsupported data type
* Improved warning with invalid row data #253
Command-line tools:
* All CLI tools which accept string arguments are now locale-aware (#237)
* All CLI tools now accept a `--version` argument (#232)
* `mdb-export`: Fix issue where exported SQL field sizes were sometimes twice the necessary size (#112)
* `mdb-export`: Improved handling of BLOBs (#250)
* `mdb-export`: Implement a serial type and relations for MySQL (#257)
* `mdb-queries` now has long option names `--list`, `--newline`, and `--delimiter`
* `mdb-schema`: Exit with an error code if the requested table is not found
ODBC:
* `SQLBindCol` now respects its TargetType (fCType) argument and converts bound data to the requested type (#23 #242)
* `SQLFetchCol` now returns `SQL_SUCCESS_WITH_INFO` if a bound column was truncated, and `SQL_ERROR` if a bound value is out of range of the target type.
* Fix handling of numeric types in ODBC driver (#255)
Build and documentation:
* Updated man pages with new SQL features and correct `MDBOPTS` information (#203)

Version 0.9.0
=============
MDB Tools is under new management! Update your bookmarks and tell your favorite
search engine that this is our new home on the WWW:
https://github.com/mdbtools/mdbtools
MDB Tools 0.9.0 builds off the fork of cyberemissary on GitHub, collects many
years of unapplied patches, and includes a number of internal improvements.
Besides a host of security fixes, GLib is now completely optional, files can
be opened completely in-memory, and many global variables have been eliminated
to facilitate thread safety.
The core library, libmdb, is believed to be thread-safe in the sense that
several handles can be opened simultaneously and passed between threads.
However, individual handles are NOT thread-safe, so don't try to do work
on a single handle from multiple threads without implementing your own
locking mechanism.
The auxiliary libraries, libmdbsql and ODBC, still have some non-reentrant
function calls. Thread safety is not promised, though the situation is
significantly improved from the 0.7 days.
The ABI has some slight changes (mostly having to do with struct layouts) so
you'll need to bump your SO numbers and such. The main changes to the API are
the introduction of a new function for in-memory parsing:
MdbHandle *mdb_open_buffer(void *buffer, size_t len, MdbFileFlags flags);
And the modification of the "mdb_set_date_fmt" function to include a handle
parameter, so that date formats can be set in a non-global fashion:
void mdb_set_date_fmt(MdbHandle *mdb, const char *);
The above function is the most common reason that old projects will fail to
compile on 0.9, and the fix is straightforward.
The previously-deprecated functions mdb_init() and mdb_exit() have been
removed. These functions did nothing; any calls to them should be excised with
prejudice.
This release introduces two new CLI tools (mdb-count and mdb-queries) and
deprecates mdb-array, mdb-header, and mdb-parsecsv. Several man pages have been
added or otherwise brought up to date.
The GNOME-based GUI tool that formerly shipped with MDB Tools has been moved to
a separate project, here:
https://github.com/mdbtools/gmdb2
It seems to compile but should probably be classified as abandonware. The
project uses a deprecated GUI toolkit, and as such gmdb2 is no longer included
in Linux distros that used to carry it.
Version 0.7.1
=============
autogen.sh is no more. Use "autoreconf -if" to bootstrap the configuration.
autoconf/automake has been updated to more recent standards.
- config.guess config.sub depcomp install-sh ltmain.sh missing ylwrap
files are now in build-aux/ directory
You'll now need autoconf >= 2.58
An experimental (buggy) version of ODBC driver that supports UCS-2 interface
is now available: libmdbodbcW.so
Note that libmdbodbc supports UTF-8 really well, so that this is usually not
needed.
Version 0.3
===========
The organization of the project files has changed a bit from that last release.
The autoconf stuff has been moved to the root directory. The include directory
has also been moved from src/include to include
