The Bitcoin Core project, launched past times Satoshi Nakamoto viii years agone too today led past times Wladimir van der Laan, aims to liberate a novel major liberate of the software most 1 time every vi months. Such a liberate (0.12.0, 0.13.0, 0.14.0…) includes most of the improvements made since the terminal major release.In betwixt major releases, the Bitcoin Core projection oftentimes offers tike releases (0.12.1, 0.13.1, 0.13.2…). These either include soft fork upgrades, which are included inward tike releases to brand opting out equally tardily equally possible. Or they include põrnikas fixes too other small-scale improvements. This weekend marks the official liberate of a novel tike release: Bitcoin Core 0.14.1. Here’s what the newest iteration of the commencement most-used Bitcoin implementation has to offer.SegWit SignalingPerhaps the most noteworthy modify inward the novel liberate affects miners, too inward detail concerns Segregated Witness (SegWit), the protocol upgrade at the middle of Bitcoin Core’s scaling roadmap. Segregated Witness is a soft fork, which way that non-upgraded nodes volition rest business office of the same network equally upgraded nodes. This is technically besides truthful for miners; they tin proceed to mine blocks without including whatever SegWit transactions if they too then choose. (Though, if they practise non upgrade at all, they may desire to convey some precautions to avoid mining on tiptop of invalid blocks.)Bitcoin Core 0.14.1 straightaway besides offers miners the selection to exclude whatever Segregated Witness transactions fifty-fifty if the soft fork activates. They tin proceed to mine blocks that entirely include “old style” transactions if they prefer.Additionally, Bitcoin Core 0.14.1 miners that prefer to exclude SegWit transactions will, past times default, all the same hollo for back upwardly for the upgrade regardless. After all, SegWit activation shouldn’t actually hold out a occupation for them: With Bitcoin Core 0.14.1, they are technically ready to avoid invalid blocks, too they tin themselves practise blocks without SegWit transactions all the same.Memory AccountingFor normal, non-mining users, the biggest modify inward Bitcoin Core 0.14.1 is in all likelihood an improvement inward retention use.Bitcoin nodes hold a buffer of recent changes to the set down of the blockchain (the “UTXO-set”) inward memory. Recent changes are most probable to modify again, too keeping this inward retention lets nodes access it equally fast equally possible. This way, nodes tin convey too validate transactions too blocks rapidly, too forrard them accordingly, thereby benefiting the whole network. Once inward a while, the electrical flow set down of the UTXO-set is “flushed”: This is when the information is stored on disc to a greater extent than permanently.Bitcoin Core 0.14.0 showed some problems estimating how much headroom is needed inward retention to perform this flush. This could conduct hold detrimental effects on low-end systems inward particular, similar some Raspberry Pi’s, too other computers alongside express memory. In Bitcoin Core 0.14.1, retention usage for the UTXO-set is calculated to a greater extent than accurately, which should assistance well-configured machines run to a greater extent than smoothly.Additionally, Bitcoin Core 0.14.1 includes a set out of smaller põrnikas fixes too optimisations.The adjacent major release, Bitcoin Core 0.15.0, is expected roughly tumble of this year.For to a greater extent than information, run across the Bitcoin Core 0.14.1 liberate notes.
