-Omni Core v0.0.11.2
-===================
-
-v0.0.11.2 is a bugfix release which resolves an issue where, in the case where a buyer accepts more than available for sale on the traditional distributed exchange, the RPC API reported an amount higher than available, and it fixes an issue with the planned feature of fee distribution system. This release also disables the alert system as per default.
+Omni Core v0.0.12
+=================
 
-v0.0.11.1 is a bugfix release which resolves a critical bug in the RPC API whereby under certain circumstances retrieving data about a sell offer may trigger a failsafe and cause the automatic shutdown of the client.
+v0.0.12 greatly improves Omni Core's performance during the initial parsing, and it includes new logic for the fee distribution system, as well as for cross-property send-to-owner transactions.
 
-This version is built on top of v0.0.11, which is a major release and consensus critical in terms of the Omni Layer protocol rules. An upgrade is mandatory, and highly recommended. Prior releases will not be compatible with new behavior in this release.

 It follows an overview and a description of the consensus rule changes:
 
-Trading of all pairs on the Distributed Exchange
-------------------------------------------------
-
-Once activated trading of any property against any other (within the same ecosystem) will be permitted on the Distributed Exchange.
-
-Due to this change the existing trading UI in the QT version is no longer suitable and has been disabled for this release.  Please use the RPC interface to interact with the Distributed Exchange in this release.  The trading UI will be re-enabled in a future version to accommodate non-Omni pair trading.
-
-This change is identified by `"featureid": 8` and labeled by the GUI as `"Allow trading all pairs on the Distributed Exchange"`.
-
 Fee distribution system on the Distributed Exchange
 ---------------------------------------------------
 
-Omni Core 0.11 contains a fee caching and distribution system.  This system collects small amounts of tokens in a cache until a distribution threshold is reached.  Once this distribution threshold (trigger) is reached for a property, the fees in the cache will be distributed proportionally to holders of the Omni (#1) and Test-Omni (#2) tokens based on the percentage of the total Omni tokens owned.
+Omni Core 0.0.12 contains a fee caching and distribution system.  This system collects small amounts of tokens in a cache until a distribution threshold is reached.  Once this distribution threshold (trigger) is reached for a property, the fees in the cache will be distributed proportionally to holders of the Omni (#1) and Test-Omni (#2) tokens based on the percentage of the total Omni tokens owned.
 
 Once activated fees will be collected from trading of non-Omni pairs on the Distributed Exchange (there is no fee for trading Omni pairs).  The party removing liquidity from the market will incur a 0.05% fee which will be transferred to the fee cache, and subsequently distributed to holders of the Omni token.
 
 - Placing a trade where one side of the pair is Omni (#1) or Test-Omni (#2) incurs no fee
 - Placing a trade where liquidity is added to the market (i.e. the trade does not immediately execute an existing trade) incurs no fee
 - Placing a trade where liquidity is removed from the market (i.e. the trade immediately executes an existing trade) the liquidity taker incurs a 0.05% fee

-Other notable changes
-=====================
-
-Raw payload creation API
-------------------------
-
-Omni Core 0.0.11 adds support for payload creation via the RPC interface.
-
-The calls are similar to the send transactions (e.g. `omni_send`), without the requirement for an address or any of the balance checks.
-
-This allows integrators to build transactions via the [raw transactions interface](https://github.com/OmniLayer/omnicore/blob/omnicore-0.0.10/src/omnicore/doc/rpc-api.md#raw-transactions).
-
-Other API extensions
---------------------
-
-An optional parameter `height` can be provided, when using [omni_decodetransaction](https://github.com/OmniLayer/omnicore/blob/omnicore-0.0.10/src/omnicore/doc/rpc-api.md#omni_decodetransaction), which is used to determine the parsing rules. If no `height` is provided, the chain height is used as default.
-
-When retrieving feature activation transactions with [omni_gettransaction](https://github.com/OmniLayer/omnicore/blob/omnicore-0.0.10/src/omnicore/doc/rpc-api.md#omni_gettransaction), then additional fields are included in the result: `"featureid"`, `"activationblock"` and `"minimumversion"`.
-
-The Omni Core client version is now also exposed under the new key `"omnicoreversion"`, as well as inter via `"omnicoreversion_int"`, when using [omni_getinfo](https://github.com/OmniLayer/omnicore/blob/omnicore-0.0.10/src/omnicore/doc/rpc-api.md#omni_getinfo). The old key `"mastercoreversion"` remains for compatibility in this version.
-
-The field `"positioninblock"` was added to RPCs retrieving or listing Omni transactions to provide visibility into the order of an Omni transaction within a block.
-
-Increased OP_RETURN payload size to 80 bytes
---------------------------------------------
-
-The maximum payload for OP_RETURN outputs was increased to 80 byte.
-
-At this point a majority of the network supports 80 byte payloads, so Omni Core can safely use the larger payload size. This can result in cheaper transactions, as there is no fallback to bare multisig encoding.
-
-Improved consensus checks
--------------------------
-
-Consensus hashing now covers much more of the state to provide wider coverage of the state. The state of properties, crowdsales and the Distributed Exchange are included in the new consensus hashing process.
-
-Checkpoints have been updated in Omni Core 0.0.11 to reflect the new consensus hashing algorithm. Seed blocks (for faster initial transaction scanning) and checkpoints are included with Omni Core 0.0.11 up to block 410,000.
-
-Various bug fixes and clean-ups
-------------------------------
+Notable changes
+===============
 
-Various smaller improvements were added Omni Core 0.0.11, such as:
+Performance improvements during initial parsing
+-----------------------------------------------
 
-- Grow balances to fit on "Overview" tab
-- Switch to "Bitcoin" tab in "Send" page when handling Bitcoin URIs
-- Improve and adjust fee warning threshold when sending transactions
-- Fix missing client notification for new feature activations
-- Fix Travis CI builds without cache
-- Fix syntax error in walletdb key parser
-- Fix too-aggressive database clean in block reorganization events
-- Fix issues related to `omni_gettransaction` and `getactivedexsells`
+Due to various improvements and optimizations, the initial parsing process, when running Omni Core the first time, or when starting Omni Core with `-startclean` flag, is faster by a factor of up to 10x. The improvements also have a positive impact on the time, when processing a new block.
