This is to prevent a spam/DoS attack where validators with zero balance get "slashed" but no validator loses any balance.

Persistent committee size per slot reduced to max 128 ( #734 )
...
* Persistent committee size per slot target 128 max 256
Cuts down the cost of verifying a shard chain and aggregating signatures for a shard chain, and also makes the shard chain signatures more usable by light clients for verification as they would only need to keep track of a max 256-sized committee.

Move to SHA256
...
SHA256 is de facto blockchain standard. Standardisation of the hash function is a prerequisite for [full standardisation of BLS12-381 signatures](https://github.com/ethereum/eth2.0-specs/issues/605 ). Blockchain projects are likely to provide a cheap SHA256 opcods/precompile, and unlikely to provide a Keccak256 equivelent. (Even WASM-enabled blockchains are likely to provide a SHA256 opcode/precompile since WASM does *not* natively support optimised SHA256 CPU instructions.) With Ethereum 2.0 embracing SHA256 the wider industry is more likely to converge towards a unified cross-blockchain communication scheme via Merkle receipts.
There are no security blockers with SHA256 (see comments by Dan Boneh [here](https://github.com/ethereum/eth2.0-specs/issues/612#issuecomment-470452562 )).

Fair proposer sampling
...
I think we want `first_committee[epoch % len(first_committee)]` as opposed to `first_committee[slot % len(first_committee)]`. The reason is that if the shuffling happens infrequently and `len(first_committee)` is a multiple of `SLOTS_PER_EPOCH` then the proposers will not be sampled fairly.
Taking this logic further, we may want to avoiding always picking the proposer from `first_committee`, e.g.:
```
validators_at_slot = []
for crosslink_committee, _ in get_crosslink_committees_at_slot(state, slot, registry_change):
validators_at_slot.append(crosslink_committee)
return validators_at_slot[epoch % len(validators_at_slot)]

Rewrite SSZ spec
...
* Implement tuples and a chunk-size reduction to 32 bytes (see #665 and #679 )
* Simplify presentation where appropriate. For example, deserialisation is implicit from serialisation (similar to `bls_sign` being implicit from `bls_verify`) and is left as an implementation exercise.
* Dramatically reduce spec size and hopefully improve readability.

Unfortunately, it's easy to assume that a merkle_root function would hash its leaves, so it should be clarified.

Bring forward changes to withdrawability from phase 1 ( #615 )
...
* Bring forward changes to withdrawability from phase 1
* The `WITHDRAWABLE` flag is removed; instead, a validator's withdrawability is determined through the `withdrawable_epoch` field (renamed and re-purposed from `withdrawal_epoch` which was not used)
* When a validator passes through the withdrawal queue, the `prepare_validator_for_withdrawal` function does not let them withdraw immediately; instead, they have to wait `MIN_VALIDATOR_WITHDRAWAL_EPOCHS`. This extra minimum delay serves no value in phase 0, but is crucial for phase 1 as the period between a validator passing through the queue and the validator being eligible to withdraw is where proof of custody challenges can come in; adding it in phase 0 is only half a line of code so easier to add it now.
* If a validator is penalized, they are no longer subject to the exit queue; instead, their `withdrawable_epoch` is set `LATEST_PENALIZED_EXIT_LENGTH` into the future and this is used to determine when the validator can withdraw
* Changes the eligibility condition for a transfer to use the `withdrawable_epoch`

Merkleise SSZ container elements ( #595 )
...
Reasons to use `merkle_hash` instead of `hash` for containers:
1) **Smaller witnesses**: `BeaconState` is a somewhat wide container (26 fields as of now, likely 30+ in phase 2). With concatenation and plain concatenation the size of the Merkle witnesses for the top level are ~32 bytes per field element.
2) **Faster incremental hashing**
3) **Consistency**: Consistent with `merkle_hash` for lists/vectors.

Updated phase 1: fork choice rule ( #586 )

Adds the crosslink committee to the fork choice rule. This is useful because it means that even if a proposal committee is byzantine and attempts to prevent a crosslink via a "balance attack" (alternating between chain A and chain B being the canonical chain), the crosslink committee can force the equilibrium to flip to one side or the other.

Attestation data contains latest crosslink, not just latest crosslink data
...
The reason to do this is that it makes it calculable from inside an attestation how many epochs the attestation spans over, which is needed for proof of custody reasons. It's a relatively small change and so arguably easier to do now than to do as a patch in phase 1.
Note that this changes the meaning of latest_crosslink.epoch, from the epoch when the latest crosslink was included to the epoch that the latest crosslink was for. This affects the line:
* `state.latest_crosslinks[shard].epoch > state.validator_registry_update_epoch` for every shard number `shard` in `[(state.current_epoch_start_shard + i) % SHARD_COUNT for i in range(get_current_epoch_committee_count(state))]` (that is, for every shard in the current committees)
But this may actually make it _more_ correct, as it means that in the case where >512 shards are processed per epoch, and so a committee from the previous epoch could get finalized in the current epoch, that would no longer count toward every shard having received a "new" crosslink.

This change allows for easier maintenance of the code and the spec by
uncoupling them. Before any edit to either document resulted in having to
synchronize the other. By adding a reference to the canonical repo for the code
we avoid having to maintain a duplicate copy here.
