+## v0 Milestone
+
+**#Status_Update_Interrupt**
+
+Here is the formal document: https://github.com/nkohen/dlcspecs-1/blob/v0-milestone/v0Milestone.md
+
+Here is an outline:
+
+* phase 1
+  - Enum outcome DLCs
+  - (unsigned) Numeric decomposition ([110](https://github.com/discreetlogcontracts/dlcspecs/pull/110))
+  - Updated phase 1 test vectors
+    - Before [130](https://github.com/discreetlogcontracts/dlcspecs/pull/130) ([125](https://github.com/discreetlogcontracts/dlcspecs/pull/125))
+    - Update after [130](https://github.com/discreetlogcontracts/dlcspecs/pull/130)
+  - Updated (generalized) contract_info ([130](https://github.com/discreetlogcontracts/dlcspecs/pull/130))
+  - Remove range outcomes
+* phase 1.5
+  - Multiple Oracles ([128](https://github.com/discreetlogcontracts/dlcspecs/pull/128))
+    - Enum
+    - Exact (unsigned) numeric
+    - (unsigned) Numeric with differences
+    - In all cases, oracles are assumed to have (1-1) corresponding outcome sets
+* phase 2
+  - Updated ECDSA Adaptor Signatures ([114](https://github.com/discreetlogcontracts/dlcspecs/pull/114)) ([117](https://github.com/ElementsProject/secp256k1-zkp/pull/117))
+  - Oracle Interface Stability
+    - Oracle TLVs/Interface
+      - Announcements
+      - Attestations ([113](https://github.com/discreetlogcontracts/dlcspecs/pull/113) or Lloyd's proposal)
+    - Solidify (numerical) base requirements
+  - Signed numeric outcomes
+  - Multi-oracle support for non-corresponding outcome sets
+  - Disjoint union DLCs
+  - Simple fraud proofs
+  - Minor Changes
+    - Optional prevTx ([98](https://github.com/discreetlogcontracts/dlcspecs/issues/98))
+    - Links between specification documents ([60](https://github.com/discreetlogcontracts/dlcspecs/issues/60))
+    - Order of inputs and outputs ([18](https://github.com/discreetlogcontracts/dlcspecs/issues/18))
+    - Requirements on change SPKs ([53](https://github.com/discreetlogcontracts/dlcspecs/issues/130))
+    - Support for 1/x shaped payout curves
+* Not included in v0
+  - DLC transfers
+  - One-sided signing with atomic payment (option-style) DLCs
+  - Compound outcome DLCs (other than disjoint union)
+  - Segwit v1 (Taproot) DLCs
+  - Lightning DLCs
+
+## Specification Writing
+
+**#Status_Update_Interrupt**
+
+* [ECDSA Adaptor Signature Specification](https://github.com/discreetlogcontracts/dlcspecs/pull/114)
+  * And corresponding secp256k1-zkp implementation
+  * **Query(Lloyd, Jesse)**
+* [Updated and generalized contract_info](https://github.com/discreetlogcontracts/dlcspecs/pull/130)
+  * Needs review and merge (phase 1)
+* [Numeric Outcome DLCs](https://github.com/discreetlogcontracts/dlcspecs/pull/110)
+  * Needs review and merge (phase 1)
+* [Multi-Oracle DLCs](https://github.com/discreetlogcontracts/dlcspecs/pull/128)
+  * Needs review and merge (phase 1.5)
+* [Preliminary Test Vector update](https://github.com/discreetlogcontracts/dlcspecs/pull/125)
+  * These have become the de facto test vectors in place of what is currently on the repo.
+  * Good to merge? (part of phase 1)
+  * **#Query(Tibo)**
+* P2P Updates?
+  * **#Query(Lloyd)**
+* Documenting loss-of-funds vectors
+  * https://github.com/discreetlogcontracts/dlcspecs/issues/132
+  * **#Discussion**
+
+## Oracle Specifications
+
+**#Status_Update**
+
+* [Exact serialization algorithm for oracle signing](https://github.com/discreetlogcontracts/dlcspecs/pull/113) merged!
+* [Oracle Attestation TLV](https://github.com/discreetlogcontracts/dlcspecs/pull/126)
+  * Good for merge?
+* [Oracle Attestation Computation Change Proposal](https://mailmanlists.org/pipermail/dlc-dev/2020-December/000002.html)
+  * **#Query(Lloyd)**
+  * **#Discussion**
+* What other work is left to do to solidify oracle specifications for v0?
+  * Specifically from the oracle's perspective, so not including things like fraud proofs.
+  * Base requirements for numeric signing
+  * **#Query(Ben, Lloyd, Tibo, all)**
