With this month's issue of the FRB Newsletter, we are thrilled to mention the revival of the FRB Host Galaxy Catalog website. See our "Software and Other Resources" section below for how to participate in an ongoing community effort to keep this resource up to date. We hope you enjoy this month's round up of FRB-related news and papers.

• FRB 20240114A was highlighted in our previous Newsletter as a recently discovered and highly active repeating FRB source. It has now been detected at uGMRT (51 bursts, 650 MHz; ATel 16494) and again at FAST (a burst storm at 1.25 GHz, with burst rates ~500/hr over the 30 minute observation; ATel 16505) as well as a bright burst at the Northern Cross Radio telescope (408 MHz; ATel 16547).
  The source was localized with EVN PRECISE to better than ~200 milliarcseconds (ATel 16542), to within the 1-sigma localization region from previous MeerKAT detections, and consistent with the previously reported host galaxy at a redshift z~0.42.

• FRB data and software on GitHub: A collection of all public data on well-localized FRBs and their host galaxies, as well as software to work with these resources. This is a community-driven effort with contributions from members of the F4, CRAFT, DSA, Realfast, and CHIME collaborations. Everyone is encouraged to contribute, especially new data on well-localized FRBs and their hosts. Pull requests and Git issues are welcome.
• The data in the above repository is used to build the FRB Host Galaxy catalog, now revived at www.frb-hosts.org, courtesy of the F4 team. Please submit issues to the frbhosts_web repository to request additions or extra features.

• Localization of fast radio bursts in Taiwan 2024 has some deadlines approaching in the coming months. Submit your abstracts before May 1st 2024.
