+## Spec alterations
+
+## Publisher Rule 1
+
+**1.0.0:** The total number of onNext signals sent by a Publisher to a Subscriber MUST be less than or equal to the total number of elements requested by that Subscriber´s Subscription at all times.
+
+**1.0.1:** The total number of onNext´s signalled by a Publisher to a Subscriber MUST be less than or equal to the total number of elements requested by that Subscriber´s Subscription at all times.
+
+**Comment: Minor spelling update.**
+
+## Publisher Rule 2
+
+**1.0.0:** A Publisher MAY signal less onNext than requested and terminate the Subscription by calling onComplete or onError.
+
+**1.0.1:** A Publisher MAY signal fewer onNext than requested and terminate the Subscription by calling onComplete or onError.
+
+**Comment: Minor spelling update.**
+
+## Publisher Rule 3
+
+**1.0.0:** onSubscribe, onNext, onError and onComplete signaled to a Subscriber MUST be signaled sequentially (no concurrent notifications).
+
+**1.0.1:** onSubscribe, onNext, onError and onComplete signaled to a Subscriber MUST be signaled in a thread-safe manner—and if performed by multiple threads—use external synchronization.
+
+**Comment: Reworded the part about sequential signal and its implications, for clarity.**
+
+## Subscriber Rule 6
+
+**1.0.0:** A Subscriber MUST call Subscription.cancel() if it is no longer valid to the Publisher without the Publisher having signaled onError or onComplete.
+
+**1.0.1:** A Subscriber MUST call Subscription.cancel() if the Subscription is no longer needed.
+
+**Comment: Rule could be reworded since it now has an intent section describing desired effect.**
+
+## Subscriber Rule 11
+
+**1.0.0:** A Subscriber MUST make sure that all calls on its onXXX methods happen-before [1] the processing of the respective signals. I.e. the Subscriber must take care of properly publishing the signal to its processing logic.
+
+**1.0.1:** A Subscriber MUST make sure that all calls on its signal methods happen-before the processing of the respective signals. I.e. the Subscriber must take care of properly publishing the signal to its processing logic.
+
+**Comment: Rule slightly reworded to use the glossary for `signal` instead of the more *ad-hoc* name "onXXX methods". Footnote was reworked into the Intent-section of the rule.**
+
+## Subscription Rule 1
+
+**1.0.0:** Subscription.request and Subscription.cancel MUST only be called inside of its Subscriber context. A Subscription represents the unique relationship between a Subscriber and a Publisher [see 2.12].
+
+**1.0.1:** Subscription.request and Subscription.cancel MUST only be called inside of its Subscriber context.
+
+**Comment: Second part of rule moved into the Intent-section of the rule.**
+
+## Subscription Rule 3
+
+**1.0.0:** Subscription.request MUST place an upper bound on possible synchronous recursion between Publisher and Subscriber[1].
+
+**1.0.1:** Subscription.request MUST place an upper bound on possible synchronous recursion between Publisher and Subscriber.
+
+**Comment: Footnote reworked into the Intent-section of the rule.**
+
+## Subscription Rule 4
+
+**1.0.0:** Subscription.request SHOULD respect the responsivity of its caller by returning in a timely manner[2].
+
+**1.0.1:** Subscription.request SHOULD respect the responsivity of its caller by returning in a timely manner.
+
+**Comment: Footnote reworked into the Intent-section of the rule.**
+
+## Subscription Rule 5
+
+**1.0.0:** Subscription.cancel MUST respect the responsivity of its caller by returning in a timely manner[2], MUST be idempotent and MUST be thread-safe.
+
+**1.0.1:** Subscription.cancel MUST respect the responsivity of its caller by returning in a timely manner, MUST be idempotent and MUST be thread-safe.
+
+**Comment: Footnote reworked into the Intent-section of the rule.**
+
+## Subscription Rule 13
+
+**1.0.0:** While the Subscription is not cancelled, Subscription.cancel() MUST request the Publisher to eventually drop any references to the corresponding subscriber. Re-subscribing with the same Subscriber object is discouraged [see 2.12], but this specification does not mandate that it is disallowed since that would mean having to store previously cancelled subscriptions indefinitely.
+
+**1.0.1:** While the Subscription is not cancelled, Subscription.cancel() MUST request the Publisher to eventually drop any references to the corresponding subscriber.
+
+**Comment: Second part of rule reworked into the Intent-section of the rule.**
+
+## Subscription Rule 15
+
+**1.0.0:** Calling Subscription.cancel MUST return normally. The only legal way to signal failure to a Subscriber is via the onError method.
+
+**1.0.1:** Calling Subscription.cancel MUST return normally.
+
+**Comment: Replaced second part of rule with a definition for `return normally` in the glossary.**
+
+## Subscription Rule 16
+
+**1.0.0:** Calling Subscription.request MUST return normally. The only legal way to signal failure to a Subscriber is via the onError method.
+
+**1.0.1:** Calling Subscription.request MUST return normally.
+
+**Comment: Replaced second part of rule with a definition for `return normally` in the glossary.**
+
+## Subscription Rule 17
+
+**1.0.0:** A Subscription MUST support an unbounded number of calls to request and MUST support a demand (sum requested - sum delivered) up to 2^63-1 (java.lang.Long.MAX_VALUE). A demand equal or greater than 2^63-1 (java.lang.Long.MAX_VALUE) MAY be considered by the Publisher as “effectively unbounded”[3].
+
+**1.0.1:** A Subscription MUST support an unbounded number of calls to request and MUST support a demand up to 2^63-1 (java.lang.Long.MAX_VALUE). A demand equal or greater than 2^63-1 (java.lang.Long.MAX_VALUE) MAY be considered by the Publisher as “effectively unbounded”.
+
+**Comment: Rule simplified by defining `demand` in the glossary, and footnote was reworked into the Intent-section of the rule.**
