Firebird 4 Release

Hello,
the first release version of Firebird 4 was published on 01.02.2021.
When can we expect UniDac support for Firebird 4?
So that we can also test Firebird 4 in interaction with our applications and UniDac.
First point, would be in any case the support for the new data types.
Without the support we can't even start our application, because we access some MON$ and RDB$ system tables and under Firebird 4 they already have the timestamp fields set to "TIMESTAMP WITH TIME ZONE".

Hello,
We support only the release versions of DBMS since beta versions or release candidates may contain errors, and the release version may differ a lot from the beta version or release candidate. Therefore, we will add support for Firebird 4 when it is officially released.

Hello,
for all who already want to test Firebird 4.
In the firebird.conf you can specify DataTypeCompatibility. This will disable the new data types from Firebird 4, so you can use Firebird 4 with Unidac.
6. Application level incompatibilities
Firebird 4 client library "fbclient" is compatible with previous versions at API level. But there may be compatibility problems for some SQL queries. Some of them were described above. Next is information about other incompatibilities.
6.1. New data types
Some expressions can return new data types that your application cannot process without its modification. This modification may take too much time, or will require changing the code of the data access components, etc. To simplify migration to new versions, you can set the DataTypeCompatibility parameter to the compatibility mode with the required version in firebird.conf or databases.conf.
DataTypeCompatibility = 3.0
This is the fastest way to get compatibility with new data types. During time you may add new data types support to your applications. Since it will happen gradually, one datatype first, then another, etc, you may set data type binding of the types that your applications still do not support.

Hi Leonard!
Please note that we have already released UniDAC 9.0.1 and IBDAC 8.0.1 with Firebird 4 support: we supported INT128, DECFLOAT and large NUMERIC types, as well as table names up to 64 characters.
The TIMESTAMP WITH TIME ZONE type is supported as a string in this release.
The full support of this type will be in the next release of IBDAC!
Should you have any questions, do not hesitate to ask!
Best regards,
Viktor

Thanks, and
FYI: connecting with fbclient (v3.07) to a v4 server does all that already..
