Mac OS X (Intel) support has been added. To build on Mac OS X from the repository sources you must have the most recent versions of bison, automake, autoconf and libtool installed.

There are known issues with the Falcon on Mac OS X build. (Bug#30564)

The Falcon record cache parameters have been altered. The falcon_max_record_memory and falcon_min_record_memory are no longer supported.

Instead, the falcon_record_memory_max, falcon_record_scavenge_threshold, falcon_record_scavenge_floor and falcon_inital_allocation parameters are now used to control the caching of records in memory within Falcon. See Section 13.6.2, “Configuration Parameters”. (Bug#30083)

Falcon would incorrectly allow creation of two tables with the same name but different case sensitivity, without raising an error, but treat the two tables as the same during further queries. . (Bug#30210)

Updating a large table without an index would lock all the records during a transaction and unlock the records individually. (Bug#30124)

Creating a tablespace with a unique name but using the same data file as an existing tablespace results in the re-initialization of the tablespace and the loss of the data contained in it. Falcon now reports an error if the data file already exists. (Bug#29511)

Using SELECT on a table that uses two INT columns with a single index would fail to return rows that queried both columns and complex comparison operators. (Bug#29319)

Falcon could occasionally report a problem with a duplicate key error during INSERT when inserting the same data into a unique column on two or more connections simultaneously. (Bug#29240)

Inserting into a table with a unique index simultaneously on two connections in a way that would cause a deadlock would cause MySQL to hang. The deadlock situation is now identified and an error will be raised. (Bug#29206)
