  • add support for null values in amqp messages

  • use cython 3.0.2 to build rbfly binary extensions

  • fix binary only decoder of rabbitmq streams messages

  • fix reading duplicate messages when re-subscribing to a rabbitmq stream

4.2.4. 2023-06-25, ver. 0.7.1

  • fix reconnection to rabbitmq streams broker, which was failing due to hidden subscriber class attributes

4.2.5. 2023-06-21, ver. 0.7.0

  • rbfly is beta software, now

  • add support for deduplication of published messages

  • add support for publishing messages with amqp application properties

  • publish performance test results for message publishing

  • include aiokafka and apache kafka in message publishing performance tests

  • fix potential buffer overflow issues when decoding message publishing confirmations

  • use cython 3.0.0b2 to build rbfly binary extensions

  • rename PublisherBatch class as PublisherBatchFast class

  • rename PublisherBatchMem class as PublisherBatchLimit class

4.2.6. 2023-05-12, ver. 0.6.2

  • fix parsing of virtual host in rabbitmq streams uri, i.e. /vhost -> vhost but / remains as /

4.2.7. 2023-03-18, ver. 0.6.1

  • fix message id value type; it is 64-bit, not 32-bit value

4.2.8. 2023-02-04, ver. 0.6.0

  • fix various buffer overflow issues

  • split batch of messages, and send multiple batches, when the batch is too big to fit into rabbitmq streams protocol frame

  • increase initial credit value to 128; this improves performance of reading messages with rabbitmq 3.11.8; the possible memory footprint of 400 MB to read messages still seems to be acceptable

  • adapt to rabbitmq 3.11.8 changes related to the handling of stream subscription credit

4.3. Year 2022

4.3.1. 2022-12-22, ver. 0.5.6

  • improve maintenance of rabbitmq stream’s subscription credit

4.3.3. 2022-11-23, ver. 0.5.4

  • fix authentication with rabbitmq streams broker (send password if specified, not username)

4.3.4. 2022-11-11, ver. 0.5.3

  • documentation improvements

4.3.5. 2022-11-01, ver. 0.5.2
