CIAO 4.8.1/4.8.2 Release Notes


CIAO 4.8.1 is distributed for the following platforms:

[WARNING]
CIAO 4.8.2

CIAO 4.8.2 is distributed for:

  • Mac OS X 64-bit 10.11 (El Capitan)

The CIAO 4.8.2 patch is identical to the CIAO 4.8.1 patch, with a fix on a bug introduced by the previous patch that only affects the OS X 10.11 (El Capitan) pre-compiled binaries.

Functionally, CIAO 4.8.1 and 4.8.2 are the same across platforms.

CIAO is no longer available for 32bit Linux operating systems or for older 64bit Linux machines (CentOS 5 era). CIAO is also no longer available for older versions of OSX (notably 10.6 and 10.7). CIAO 4.7 is still available for users who are unable to upgrade. More details on the Platform Support page.
