The Haiku open-source operating system project inspired by BeOS published their latest monthly report to outline progress made over the past month.

Haiku OS is now better handling unreliable network connections by fixing their TCP implementation to re-transmit packets during connection startup when needed. This will avoid connections failing on unstable network connections.

Haiku has also enabled the checksum-seed feature with its EXT4 driver to match it being enabled by default on recent Linux kernel versions. In turn this allows the EXT4 driver to be able to read and write to partitions created with the default EXT4 settings on Linux.

Also on the data side, there have been some Haiku crash fixes when creating large files as well as the overwriting of hard-linked files while using RAMFS.

Haiku also landed a fix to its linker script and updated packaging to once again allow their RISC-V port to boot.
