Cisco ASA software update frequency

How frequent are Cisco ASA updates released, for arguments sake how many updates for ASA 9.14(3) and 9.15(1) have been released over a 12 month period? I cant find a full version release history for each version online, does anyone have a way of viewing a release history, or based on experience of managing such devices, how frequently are ASA updates released to consumers? Where you could see the latest release for a specific version, and when that was released?

thanks - just looking at release dates there it seems to be similar to Microsoft, with monthly updated versions.

Do Cisco ASA updates work in a cumulative manner like most companies now seem to operate toward?

Thank you, what I was hinting at was if say you had fallen behind with new releases, can you simply apply the latest available update, or do you have to patch consecutively through the released versions?

From that same link:

We strongly encourage you to upgrade to a fully tested Maintenance or Feature release when it becomes available.

To me that sounds like you would go straight to the latest version. Upgrade to a fully tested = I interpret that as skipping those missed.

Does Cisco send you notification of new releases?

Not me personally I don't work on the support side of things, it is just for some general audit purposes that we need to asses how efficiently patching of network devices is working. I will check that the necessary team are at least being alerted to new releases.

New to Cisco patching, I presume the version of ASA is specific to the firewall model. Newer models, work with newer versions of ASA, and the latest versions of ASA aren't available for older hardware.

To a point yes the same code for 5515, 25, 45 etc but different code for a 5516 (different chassis)

>>the latest versions of ASA aren't available for older hardware

All Cisco equipment 'Still in support' will get updates, only when it goes end of support, do they stop producing updates, even then, in special circumstances  they will they release an update (if there a major CVE or somehitng for example).
