# Appendix F: Changelog and Release Notes

## F.1 3.12

Released on April 19th, 2026

### F.1.1 Changelog

#### F.1.1.1 Security

- Don't use the Low IL temp directory when elevated (thanks Richard Warren for responsibly disclosing, bug #1326)
  This stops a possible privilege escalation for installers running as SYSTEM.

#### F.1.1.2 Minor Changes

- Added StartsWith[S], EndsWith[S], Contains[S], IsLowerCase and IsUpperCase LogicLib operators.

#### F.1.1.3 Build System

- Support Python older than 3.6 again (bug #1325)

Released on March 8th, 2025

### F.2.2 Changelog

#### F.2.2.1 Security

- Retry creating restricted $PLUGINSDIR (thanks Sandro Poppi for responsibly disclosing, bug #1315)
  This stops a possible privilege escalation. A malicious actor can create the temporary plugins directory ($PLUGINSDIR) at just the right time and fill it with malicious files that the installer might use. Installers running as SYSTEM use `C:\windows\temp` which is accessible by all users on the system. Any user can use this bug to gain SYSTEM privileges by winning the race condition with an installer that starts as SYSTEM.

## F.60 2.16

Released on April 7th, 2006

### F.60.1 Release Notes

- The script compiler, makensis, builds and works on big-endian platforms. This change enlarges the portability range of NSIS to theoretically every POSIX platform. Please report any incompatibility with specific platforms or build-tools.
- The internal changes made to support big-endian platforms also pave the road to x64 installers. There is now a central function which writes data to disk. This function currently only converts the endianity of integers, but it can be changed to selectively write 64-bit integers. Hopefully, there'll soon be a simple method of compiling a script to both x86 and x64 installers.
- Changing Source/exehead/fileform.h to alter the internal structure of installers is no longer enough. The compiler has its own definitions of the structures which must also be changed in Source/fileform.cpp. In the future, fileform.cpp should be automatically generated from fileform.h, but for now, the synchronization must be done manually.

### F.60.2 Changelog

#### F.60.2.1 Major Changes
