Cronus Zen firmware 2.3.2 and Zen Link 2.1.4: what changed, and should you update?

Cronus's current guide lists firmware 2.3.2 (18 August 2026) as the latest Cronus Zen release and 2.3.3 Beta 1 (8 September 2026) as a beta; the 2.3 series added script storage and maths functions, GameSir G7 Pro support and support for the unified Zen Link firmware, and fixed slot readback and Bluetooth clearing. Zen Link's own 2.1.3 and 2.1.4 updates of August 2026 changed its status light. The full history is in the firmware and Zen Studio changelog, and every step and error of updating is in Firmware: update, downgrade, recovery.

What changed in each 2.3 release?

Each row holds only what Cronus's changelog lists.

Release	What Cronus lists	What it means for you
2.3.0, 2 July	GameSir G7 Pro controller support; BVARs, 1,024 extra 16-bit persistent values per slot for scripts; a high-resolution Mouse Ballistics Curve; improved audio handling and Elite Series 2 detection	G7 Pro pads work through the Zen. BVARs let a script keep more of your settings after unplugging. The ballistics curve maps mouse movement to aim movement
2.3.1, 9 July	A fix for a slot 8 readback issue	Readback is the Zen handing a slot's contents back to Zen Studio, used to verify and back up slots
2.3.2, 18 August	Trigonometry functions for scripts (sin, cos, tan, asin, acos, atan2); support for the unified Zen Link v1/v2 firmware; Clear Bluetooth now fully unpairs a connected device; DualShock 4 and DualSense light bar and rumble behave the same over USB and Bluetooth	The Zen side of the August Zen Link update, and the fix if a pad stayed paired after clearing Bluetooth
2.3.3 Beta 1, 8 September	A fix for a race condition in slot readback	A timing fault when the Zen reads slots back

What the script items mean if you only load scripts

BVARs and the trigonometry functions are for script writers. They matter to you in one way: a script that uses them needs firmware that has them, which is 2.3.0 or later for BVARs and 2.3.2 or later for trigonometry. Cronus's scripting guide names circular motion and smooth oscillation as typical uses of sin and cos, so expect them in scripts that move a stick in patterns. If a script's notes name a firmware version, match it.

The changes that stop older scripts compiling came from the tool, not the firmware: Zen Studio Live 1.0.7 (18 August 2026) removed PVAR_1 to PVAR_16, and 1.0.2 removed get_mk and set_mk. The Zen Studio updates tracker lists every tool release.

What did Zen Link 2.1.3 and 2.1.4 change?

Zen Link, the Wi-Fi module behind PS5 Native Mode, has its own firmware.

Release	Date	What Cronus lists
2.1.3	18 August 2026	One firmware for Zen Link v1 and v2; improved LED status signals; general stability
2.1.4	20 August 2026	A tap of the config button cycles the brightness: dim (the default), four steps, max, off, then dim again. Holding it over five seconds enters BLE mode to change the Wi-Fi settings; a tap leaves it, and nothing changes unless you submit new settings. Idle is now a steady dim white instead of two white blinks

Zen firmware 2.3.2 and Zen Link 2.1.3 share a date and a subject; Cronus does not say one requires the other, but updating the Zen to 2.3.2 keeps the pair matched. If the Zenlink app was already open when you hold the button, Cronus says to restart it.

On Cronus's Status Light page, colour shows which part is reporting and rhythm shows how it is going. A normal start runs cyan, yellow if a saved Native Mode is found, blue while joining Wi-Fi, two green flashes, then steady dim white. Red always means a failure: quick blips clear in about ten seconds and can be retried, while long blinks never clear and need support. The full table is on PS5 setup.

Should you install the 2.3.3 beta?

Cronus labels 2.3.3 Beta 1 a beta and lists one change, the slot readback fix. Its guide says nothing else about betas: no install route and no known issues. The trade-off is the usual one: a beta delivers a fix sooner, while the release is the build Cronus presents as the latest. If Zen Studio reports that it cannot read back a slot when you program, the beta's fix is aimed at that, and Zen Studio Live 1.0.9 already lets you skip those slots and program the rest. If programming works, stay on 2.3.2.

How do you update to 2.3.2?

Firmware goes on through Zen Studio Live in Chrome. In short, from Cronus's Update Firmware page:

1. Unplug every cable from the Zen.
2. Hold the small blue button on the back of the Zen and, still holding it, plug a USB data cable into the top port (CONSOLE/PC).
3. In Zen Studio Live, click Update Firmware (bottom left), then Connect Device, choose Cronus Zen and click Connect.
4. Click Update to latest and leave the cable and the page alone until it shows Firmware updated.

Cronus warns that interrupting it can leave half-written firmware. If the Zen then reports 0.0.0, or Cronus Zen is missing from the list, the full procedure has the fixes.

Zen Link updates itself. Cronus's updating page says the update starts over Wi-Fi about 30 seconds after the module connects, with no cable, PC or app. Fast blue blinking means downloading; steady blue for up to about 45 seconds means installing, when Cronus says not to remove power. An original V1 needs a one-time upgrade first, covered in step 2 of PS5 setup.

What should you check after updating?

Check	How	Why
The version	Zen Studio Live's success screen shows the installed version	Confirms 2.3.2, not an interrupted write
Zen Studio Live is current	Reload when prompted; 1.0.9 is the newest Cronus lists	1.0.9 fixed Program attaching the wrong BVAR to a slot after slots were reordered
Your slots	Connect PROG USB, choose Cronus Bridge, read the slot list	Reprogram from your own .gpc files if anything is missing; script slots and memory
Inputs reach the console	In a console menu, move the left stick, confirm and go back; then try every input in a game	Cronus's own test; watch the console screen, not the Zen
Bluetooth pads	If a pad lingered after clearing Bluetooth, clear and pair it again	Bluetooth pairing
Zen Link	The light settles on steady dim white; Zen Studio Live's status bar shows the module's firmware version	Dim white is idle and healthy

If a script misbehaves after the update, script not working works through the causes in order.
