## AI overview

ReactOS Newsletter 54 reports fixes that reduced installer memory requirements to 24MB and lowered memory use after boot by about 20MB. It also discusses unresolved hardcoded-size issues in the CSR_API_MESSAGE data structure that could cause crashes.

## Source excerpt

Memory Usage The minimum required memory for ReactOS has been creeping up for some time now, mainly due to the installer. In general, the developers knew that the memory required by ROS after the install was nowhere as high as during the install. Most assumed there was some kind of memory leakage happening, whether it be in the installer or even in the memory manager. It was an issue many people wanted addressed but it wasn't until Alex Ionescu took a look that the problem was resolved.
