IBM i ACS 1.1.9.12 is Now Available

…and it has a couple of cool/must-have updates

Current Latest Version

• Version 1.1.9.12 — Build date: April 2026

This is the freshest drop. IBM pushes these updates a few times a year, so always grab the newest one.

Previous Recent Releases

• 1.1.9.11 — January 2026 (includes a critical security fix)
• 1.1.9.10 — November 2025

Why You Should Update Right Now

Version 1.1.9.11 fixed a nasty XML External Entity (XXE) injection vulnerability (CVE-2025-66516) that could let an attacker sneak bad stuff into a crafted PDF/XFA file. IBM strongly recommends ditching anything from 1.1.9.8 through 1.1.9.10 and jumping straight to 1.1.9.11 or newer. Security first, folks — your IBM i environment will thank you.

The April 2026 release (1.1.9.12) continues the usual mix of bug fixes, small enhancements, and security hardening. IBM doesn’t always list every tiny change, but these cumulative updates keep the 5250 emulator, Data Transfer, Schemas, Run SQL Scripts, and all the other goodies humming along nicely.

What’s New – All Focused on Run SQL Scripts

This release is laser-focused on making life easier when you’re working with source members and SQL examples. Here’s the good stuff:

• Support for the SELF utility (System-wide Entry Level Feedback – very handy for system and job-level controls)
• Better saving to Source Physical Files
  • No more sneaky x’25’ line endings inserted when you save. (Requested here)
  • Now enforces the actual record length instead of wrapping lines. (Requested here)
  • Nice usability improvements to the Source Physical File chooser dialog.
• 13 brand new “Insert from Examples” (these are gold for quick reference) Db2 for i Services – SELF examples:
  • System-wide controls
  • Job-level controls
  • Log Queries
  • Removing historical rows
  • Initial Stack
  • Top occurrences
  • QA use case example
  IBM i Services – Security focused:
  • Who is creating objects in the IFS root
  • Who is creating objects in the /QOpenSys subdirectory
  • IFS first-level directories that are open to attack
  • IFS subdirectory object attack vector check
  • IFS home directory ownership
  SYSTOOLS:
  • Generate spreadsheet and send email example

IFS first-level directories that are open to attack – we should all be playing with this one immediately!!

Bottom Line

If you live in Run SQL Scripts (and most IBM i programmers do), this update is worth grabbing immediately. The SELF examples alone will save you hours of hunting through the docs, and the improved save-to-source behavior fixes two long-standing annoyances that used to make you curse under your breath.

As we say on the green screen: “Why fight with line endings when ACS can just behave itself?“

How to Get It

Head over to the official page: https://www.ibm.com/support/pages/ibm-i-access-acs-updates

You’ll also find the base package and related PTFs (for the IBM i side) linked from: https://www.ibm.com/support/pages/ibm-i-access-client-solutions-5733xj1

Pro tip: Fire up ACS and use the built-in “Check for Updates” feature — it’s the lazy (and smart) programmer’s way to stay current without bookmarking IBM pages.

Quick Installation Notes

• Works on Windows, Linux, and macOS.
• No separate IBM i Access Family license needed anymore for 5250 emulation or Data Transfer (since version 1.1.9.1).
• Windows users sometimes get extra GSKit security updates bundled in.

Keep your ACS client patched, and you’ll avoid those “why is my emulator acting weird?” moments at 2 a.m. As we like to say on the IBM i side: an unpatched ACS is like leaving your library list wide open, it’s just asking for trouble.

Stay current, stay secure, and happy coding!
