Pausing a directory stops scanning (gh#syncthing/syncthing#3965). * Ignore patterns can now be set at directory creation time, and for paused directories (gh#syncthing/syncthing#3996). * It is no longer possible to configure the GUI/API to listen on a privileged port using the standard settings dialogue (gh#syncthing/syncthing#4020). * The device allowed subnet list can now include negative ("!") entries to disallow subnets (gh#syncthing/syncthing#4096). * Doing "Override changes" now uses less memory (gh#syncthing/syncthing#4112). - Require golang.org/x/net/context on openSUSE older than openSUSE Leap 15.x. - Update to version 0.14.27: * Devices can now have a list of allowed subnets (advanced config) (gh#syncthing/syncthing#219). * The transfer rate units can now be changed by clicking on the value (gh#syncthing/syncthing#234). * UI text explaining "Introducer" is improved (gh#syncthing/syncthing#1819). * Advanced config editor can now edit lists of things (gh#syncthing/syncthing#2267). * Directories created for new directories now obey the user umask setting (gh#syncthing/syncthing#2519). * Incoming index updates are consistency checked better (gh#syncthing/syncthing#4053). - Update to version 0.14.26: * Discovery errors are more clearly displayed in the GUI (gh#syncthing/syncthing#2344). * The language dropdown menu in the GUI is now correctly sorted (gh#syncthing/syncthing#3913). * When there are items that could not be synced, their full path is displayed in the GUI. - Update to version 0.14.25: * Improve "Pause All"/"Resume All" icons (gh#syncthing/syncthing#4003). * There are now mips and mipsle builds by default (gh#syncthing/syncthing#3959). * The "overwriting protected files" warning now correctly handles relative paths to the config directory (gh#syncthing/syncthing#3183). * The experimental KCP protocol for transfers over UDP has been merged, although it's not currently enabled by default (gh#syncthing/syncthing#804). - Update to version 0.14.24: * lib/sync: Fix a race in unlocker logging (gh#syncthing/syncthing#3884). * Make links and log messages refer to https instead of http where possible (gh#syncthing/syncthing#3976). * The default number of parallel file processing routines per directory is now two (previously one), and the number of simultaneously outstanding network requests has been increased. * The UI now contains buttons to pause or resume all directories with a single action. - Update to version 0.14.23 (changes since 0.14.21): * Leading and trailing spaces are no longer stripped in the GUI password field (gh#syncthing/syncthing#3935) * The GUI shows remaining amount of data to sync per directory (gh#syncthing/syncthing#3908). * There should no longer be empty entries in the global log (gh#syncthing/syncthing#3933). * Weak hashing is now by default only enabled when it makes sense from a performance point of view (gh#syncthing/syncthing#3938). - Update to version 0.14.21 (changes since 0.14.19): * There is now a warning when adding a directory that is a parent of an existing directory (gh#syncthing/syncthing#3197). * Using -logfile flag together with -no-restart now causes an error instead of silently failing (gh#syncthing/syncthing#3912). * Weak hashing is now disabled completely when the threshold percentage is > 100 (gh#syncthing/syncthing#3891). * Rate limiting now actually works on ARM64 builds again (gh#syncthing/syncthing#3921). * Fix an issue where UPnP port allocations would be incorrect under some circumstances (gh#syncthing/syncthing#3924). * Weak hashing is a bit faster and allocates less memory. * The hashing performance reported at startup now includes weak hashing. * The GUI "network error" dialogue no longer shows up as easily in some scenarios when using Syncthing behind a reverse proxy. - Update to version 0.14.19: * Changing bandwidth rate limits now takes effect immediately without restart (gh#syncthing/syncthing#3846) * The event log (-audit) can now be directed to stderr for piping into an another application (gh#syncthing/syncthing#3859). * A panic on directory listing at startup has been fixed (gh#syncthing/syncthing#3584). * When a directory is deleted, the .stfolder marker is also removed. The ignore file and .stversions directory are retained, if present (gh#syncthing/syncthing#3857). * Several scenarios where a device would get stuck with 'not a directory' errors are now handled again (gh#syncthing/syncthing#3819). * Third party copyrights in the about box are now more up to date (gh#syncthing/syncthing#3839). * Hashing performance has been improved (gh#syncthing/syncthing#3861) - Update to version 0.14.18: * Fix connections to older Syncthing versions being no longer closed due to an unmarshalling message: 'proto: wrong wireType = 2 for field BlockIndexes' (gh#syncthing/syncthing#3855). - Update to version 0.14.17: * Panics caused by corrupt on disc database are now better explained in the panic message (gh#syncthing/syncthing#3689). * Statically configured device addresses without port number now correctly defaulted to port 22000 again (gh#syncthing/syncthing#3817). * Inotify clients no longer cause 'invalid subpath' errors to be displayed (gh#syncthing/syncthing#3829). * Directories can now be paused (gh#syncthing/syncthing#215). * "Master" directories are now called "send only" in order to standardise on a terminology of sending and receiving changes (gh#syncthing/syncthing#2679). * Pausing devices and directories now persists across restarts (gh#syncthing/syncthing#3407). * A rolling checksum is used to identify and reuse blocks that have moved within a file (gh#syncthing/syncthing#3527). * Syncthing allows setting the type-of-service field on outgoing packets, configured by the advanced setting "trafficClass" (gh#syncthing/syncthing#3790). * Which device introduced another device is now visible in the GUI (gh#syncthing/syncthing#3809).
