Version 1.16.0 (10 Dec 2020)

Note: this is the first release since forking from kyuupichan/electrumx. kyuupichan has the electrumx name on PyPI, so we needed a new name there. We are using the e-x name on PyPI, so you can install this package via e.g. pip install e-x.

  • security: a vulnerability has been fixed that allowed a remote attacker to crash electrumx if peer discovery was enabled (#22)

  • fixed some peer-discovery-related bugs (e.g. #35)

  • ENV: when using Bitcoin, the COIN ENV var can now be set to Bitcoin. For compatibility, using BitcoinSegwit will also keep working. (#5)

  • session resource limits: made more useful in general. connection-time-based grouping has been removed (#70). Disconnects of over-limit sessions happen sooner (4b3f6510). Subnet sizes for IP-based grouping can now be configured (a61136c5).

  • protocol: mempool.get_fee_histogram now returns fee rates with 0.1 sat/byte resolution instead of 1 sat/byte, and the compact histogram is calculated differently. (#67)

  • performance: bitcoind is now queried less frequently as estimatefee, relayfee, and server.banner requests are now cached (#24)

  • performance: json ser/deser is now abstracted away and the ujson and rapidjson exras can be used for somewhat faster block processing. (#11)

  • multiple other small performance improvements
