Centrifuge 1025 - Release Notes Highlights

This release is packed with new features and a few breaking changes. Most notably, the definition of the NAV has changed. So far, the NAV represented the so called assets under management (abbreviated by AUM) which are represented by the evaluation of existing loans:

- NAV := NAV(Loans)

With the introduction of Pool Fees, the definition of the NAV needs to be extended due to the reducing effect which the sum of pending pool fees have on the pool valuation, i.e. they represent the negative part. Please note that the Pool Fees NAV does not include disbursement amounts which can be paid during epoch execution because these already reduce the reserve.

+ NAV := min(PoolReserve + NAV(Loans) - NAV(PoolFees), 0)

Please replace any existing reserve and NAV query with the new runtime API added in #1703:

let { navAum, navFees, reserve, total: navTotal } =
    await api.call.poolsApi.nav(poolId)

Please note that runtime API metadata is not included in the v14 metadata such that you need to add type and runtime API call decorations manually.

Altair 1034 - Release Notes Highlights

The Altair system has not received an update for an extended period, and we apologize for any inconvenience this may have caused. This recent update aligns Altair's runtime environment with that of the Centrifuge runtime, ensuring that all modifications mentioned previously, as well as those introduced in subsequent releases, are now incorporated into Altair:

• Centrifuge Client v0.10.35 & Centrifuge 1024
• Centrifuge Client v0.10.34 & Centrifuge 1023
• Centrifuge Client v0.10.31 & Centrifuge 1020

❗️It's crucial to acknowledge that version 0.10.35 of the Centrifuge Client, which was not previously activated for Altair, introduced several breaking changes that could potentially disrupt existing workflows for node operators ❗️
