[PD] [PD-announce] iemmatrix 040 released

iemmatrix 0.4.0 "double square" aka (040²)ⁿ has been released last night.

https://deken.puredata.info/library/iemmatrix/0.4.0

**developed for science**

most notable features:

• 23 years of relentless development
• 130 battle tested objects
• 13473 lines of spellchecked C-code (without docs!)
• 5575 lines of analyzed Pd-code (without docs!)

**used in science**

NEWS

• multichannel support
  • optional: works out of the box with Pd>0.54
  • also works with older Pds
• improved resiliency against system incompatibilities
  • the core will work on very old systems and very new systems
  • some specialized objects that require 3rd party libraries might only run on newer systems (but you can still use most objects if your system does not meet these requirements)
• lots of bugfixes

notes on compatibility with older OSs

† the Deken binaries for Linux require GLIBC-2.29, such as found on 
Linux distributions released after 2020, such as Ubuntu/20.04 "focal" or 
Debian/11 "bullseye"; but notably *not* on Debian/10 "buster".

‡ the Deken binaries for macOS have been tested to work back to OSX 
10.11 "El Capitan".
some specialist objects require a newer version of macOS however. e.g. 
heavy math like decomposing matrices with [mtx_eig], [mtx_qr] and 
[mtx_svd] requires macOS 10.14 "Mojave", as does [mtx_bessel]. 
[mtx_sndfileread] requires macOS 11 "Big Sur". if you do not need these 
specialized objects, then "El Capitan" will do nicely.

independent of iemmatrix, we strongly suggest that you use an up-to-date 
operating system for the safety of yourself and others.
