Here we summarise some of the important changes for Period 106:

• In sight of the future deployment of Dual-Anonymous Peer Review (DAPR, see accompanying announcement), ESO strongly encourages applicants to formulate the scientific rationales of their proposals following the anonymisation rules and examples described in this link, which also gives a detailed description of the DAPR paradigm.
  
• As previously announced, ESO is now requesting all science users to provide more detailed information in their User Portal profile. Users failing to do this will not be able to submit a proposal as PI and/or as CoI.
  
• Since Period 105, ESO proposals must be submitted using the new web-based tool p1. The LaTeX ESOFORM has been retired. Users are encouraged to get familiarised with the new system well before the deadline, by accessing the p1 introduction webpage and using the p1demo tool. Further details can be found in this Call for Proposals document and in the p1 ESO Messenger article.
• Target of Opportunity runs are now allowed as part of Monitoring Programme proposals.
• Normal, Large and Monitoring Programme proposals will be accepted for OmegaCAM and VIRCAM without restrictions on atmospheric conditions, lunar phase or RA range, but for two Periods only. Both instruments are expected to be scheduled until Period 107.
• The visitor focus of the 3.6-metre telescope is not offered during Period 106 due to the installation and commissioning of NIRPS. The Nasmyth A focus of UT1 is available for a Visitor Instrument during the whole Period 106. Further, two visitor foci for an interferometric instrument are available in the VLTI laboratory. Interested users should consult Section 3 of the Call for Proposals document.
• To allow longer Normal Programmes for nFLASH-230 at APEX that request PWV larger than two millimetres, the maximum length of Normal Programmes - only for this instrument - has been raised to 199 hours.
