+
+This is the monthly report for April 2024.
+
+# Introduction
+
+This is some news regarding the development of FusionInventory agent 3.0.
+
+
+# Why no news since couple months?
+
+I took a break from development to take some time to think about Agent 3.0.
+
+After the first testing session (in November 2023) by users of the new agent, some things are good, but others are not, especially in 2024.
+
+# List of good points
+
+This is the list of good points: 
+
+* agent run without many problems (some fixes are be made during the test)
+* agent seems stable
+* data got are ok
+* new file structure of the agent is ok
+* new data structure (JSON) is ok
+* agent in one exe is better
+
+
+# List of bad points
+
+* agent is one exe (archive) and to run, uncompress all files in temp folder; this operation takes time and need clean after.
+* compilation is not simple as I want, because need compiles the agent on each operating system
+* unable to sign the agent exe in this case to prevent a problem with Windows 11
+* the cleaning of existing code is very complex to do
+* the exe is big and contains too many files
+* the new disk program can be used to do modifications on disk partition and not very good for the security
+* same thing with PERL on the device for security reasons (on the server and better for client windows computer), I need prevent have perl interpreter on computers
+* the agent need too many PERL module to install on system or added in archive
+
+
+# Solution: develop the agent in RUST
+
+After much thought, the best solution is to code it in GO or RUST to have a only one exe.
+
+I have compared the 2 languages, and I decided to use **RUST**, it seems the best choice for the FusionInventory agent.
+
+Good points for this new agent: 
+
+* small exe
+* fast execution
+* small memory footprint
+* cross compiling for operating systems
+* better error management, detect many when compile it
+
+
+# Code has started?
+
+Yes, the development of the agent has started.
+
+I started from scratch, but in fact no, I use many parts for the new agent coded last months:
+
+* get same files structure
+* get part of data conversion
+
+I started with the local inventory module; I have coded about 15% of it in couple days. It's fast to code and pleasant to do.
+
+I'm very excited by the agent. It is fast to run (yes, I tested it) and quickly to code!
+
+I think the local inventory will be at a high percentage in June/July, stay connected ^_^
