+The LHCb collaboration is happy to announce the official release of the [LHCb
+Ntupling Service](https://opendata-lhcb-ntupling-service.app.cern.ch/): a web
+service for on-demand production and publishing of custom LHCb open data. This
+provides the public access to both Run I, and for the first time, Run II pp
+data collected by LHCb. This amounts to over 4 PB of data to explore! The image
+displays an event recorded during Run II.

+  <br/><em>A typical LHCb event fully reconstructed during data taking on May 9th 2016.</em>
+  <br/><em>Particles identified as pions, kaon, etc. are shown in different colours.</em>
+</p>
+
+This follows the release of the full [Run I pp data on the CERN Open Data
+Portal](/docs/lhcb-releases-entire-run1-dataset) in December 2023. While for
+the previous release, knowledge of the LHCb software stack was necessary for
+subsequent analysis of the released data, this is no longer the case for users
+of the LHCb Ntupling Service. Instead, custom ntuples are produced containing a
+collection of physics objects and quantities based on user specifications. The
+Ntupling Service serves as an all in one place for users to request custom
+ntuples with LHCb data, track the request process, communicate with the LHCb
+open data team, and download the resulting ntuples.
+
+During the ntuple creation step, users interact with the [LHCb Ntuple
+Wizard](https://inspirehep.net/literature/2637214), providing an intuitive
+step-by-step process for specifying their ntuple configuration. This process
+consists of (1) selecting a physics object of interest, (2) choosing a
+corresponding dataset, and (3) specifying the configuration of the
+corresponding ntuples.
+
+This release marks a significant advancement in the LHCb open data
+infrastructure, and is an exciting step for the larger open data community,
+where the barrier for entry of data analysis is lowered without the need for
+any experiment specific software. The release is accompanied by a growing
+[usage guide](https://lhcb-opendata-guide.web.cern.ch/ntupling-service/) with
+a detailed walkthrough for request submission and tracking, in addition to
+analysis example workflows with the resulting ntuples.
+
+This work was carried out through the [Data Processing & Analysis
+project](https://lhcb-dpa.web.cern.ch/lhcb-dpa/) of LHCb in collaboration with
+[CERN’s Information Technology
+Department](https://information-technology.web.cern.ch/). The LHCb
+collaboration would like to thank the CERN Information Technology Department
+for co-designing, co-developing and co-operating the new service.
