Release preparation (0.23.0) (#1598)

* Script concatenating next release notes * Concatenate next release notes I ran ... ``` scripts/cat-files-in-directory-sorted-by-committer-date docs/release-notes/next >> docs/release-notes/RELEASE-NOTES-0.23.0.md && rm -r docs/release-notes/next ``` ... then ... ``` git log -p -w --color-moved ``` ... for checking no spurious notes excluded/excluded. * Place release notes in correct location I removed placeholder lines. I removed spurious line: ``` * Does this. ``` I checked outcome with `git log -p -w --color-moved`. * Add focus

 # About this release
 
-[This release][this-release] is focused on TODOFILLMEIN.
+[This release][this-release] is focused on the Bitcoin-NG Proof of Fraud.
 It:
-* Does all the things mentioned temporarily in files [/docs/release-notes/next/PT-*.md](/docs/release-notes/next/). I.e. each mentioned item is meant to be placed in a file named as the Pivotal Tracker ticket number in which scope the mentioned item is.
-
-TODO: When preparing the release, concatenate all `/docs/release-notes/next/PT-*.md` files and place them in this file.
+* Changes difficulty from a floating point number to an integer value as seen in P2P message PING, and node status.
+* Adds fixed gas limit per micro block
+* Adds fixed gas to all transactions (contract create and contract call transactions use the fixed gas plus gas needed for their execution)
+* Modifies mempool to select transactions up to the gas limit per micro block
+* Adds Proof of Fraud (PoF) for reporting a mining leader that creates forks in a generation. This affects consensus.
+* Restructures the serialization format for headers by shrinking the version field to 32 bits, and by introducing a flags field in 32 bits. This affects consensus.
+* The state channel fsm will now terminate if it detects that someone is
+  trying to close the channel on-chain.
+* Adds built in functions `String.length` and `String.concat` for Sophia strings.
+* Fixes a Sophia bug where None would match a Some(x) pattern
+* Events (logs) generated by the VM are added to the call state tree. This affects consensus.
+* Fixes the VM `CALL` instruction to place `0` (as opposed to `1`) on the stack if the value operand is not covered by the balance of the currently executing account.
+* Fixes the Sophia VM primitive operations to check that the specified value is covered by the balance of the currently executing account - regardless of whether the value is used by the primop.
+* Fixed a bug that affected syncing of large generations (> 64K).
+* Moves Sophia value encoding/decoding from AEVM bytecode to Erlang code. This affects consensus.
+* Makes execution of some chain related instructions in contracts more efficient.
+* Makes the TIMESTAMP instruction deterministic by using the timestamp of the current micro block. This affects consensus.
+* Makes the DIFFICULTY instruction deterministic by using the difficulty at previous key block. This affects consensus.
+* Make the gas cost of oracle VM primitive operations proportional to the TTL of the objects (oracles, queries, responses) on state trees. This impacts consensus.
+* Improves stability of the user HTTP API.
