Syncthing: download ældre versioner

What's Changed
Built with Go 1.27.3.

Fixes
- fix: handle missing max-sequence file entries by @calmh in #10912
- fix(sqlite): avoid early garbage collection of deleted recv-enc files by @calmh in #10916
- fix(sqlite): do not generate unbounded prepared statements (ref #10913) by @calmh in #10915
- fix(discover): skip unnecessary identical global announce updates; obey retry-after by @calmh in #10918
- fix(protocol): convert panics on bad data to protocol errors by @calmh in #10923
- fix(model): verify local change before applying metadata shortcut (fixes #10924) by @calmh in #10925

Other
- build(deps): update dependencies by @calmh in #10917
- chore(protocol): add protovalidate validation of incoming messages, reasonable limits by @calmh in #10838

Major changes in 2.1
- Devices and folders can now be grouped in the GUI by setting the new
group attribute.
- HTTP and HTTPS proxies with support for CONNECT can now be used, in
addition to the existing support for SOCKS proxies (the environment
variable all_proxy=https://...).
- Block indexing can be turned off for folders where it's more desirable to
optimise for reduced database size and overhead than minimal transfer
size (the blockIndexing attribute on folder configuration).
- GUI login session duration can be configured to be longer or shorter than
the default one week, or set to infinitely long. The cookie path can also
be adjusted. (The sessionCookieDurationS and sessionCookiePath
attributes in the GUI configuration.)

Major changes in 2.0
- Database backend switched from LevelDB to SQLite. There is a migration on
first launch which can be lengthy for larger setups. The new database is
easier to understand and maintain and, hopefully, less buggy.
- The logging format has changed to use structured log entries (a message
plus several key-value pairs). Additionally, we can now control the log
level per package, and a new log level WARNING has been inserted between
INFO and ERROR (which was previously known as WARNING...). The INFO level
has become more verbose, indicating the sync actions taken by Syncthing. A
new command line flag --log-level sets the default log level for all
packages, and the STTRACE environment variable and GUI has been updated
to set log levels per package. The --verbose and --logflags command
line options have been removed and will be ignored if given.
- Deleted items are no longer kept forever in the database, instead they are
forgotten after fifteen months. If your use case require deletes to take
effect after more than a fifteen month delay, set the
--db-delete-retention-interval command line option or corresponding
environment variable to zero, or a longer time interval of your choosing.
- Modernised command line options parsing. Old single-dash long options are
no longer supported, e.g. -home must be given as --home. Some options
have been renamed, others have become subcommands. All serve options are
now also accepted as environment variables. See syncthing --help and
syncthing serve --help for details.
- Rolling hash detection of shifted data is no longer supported as this
effectively never helped. Instead, scanning and syncing is faster and more
efficient without it.
- A "default folder" is no longer created on first startup.
- Multiple connections are now used by default between v2 devices. The new
default value is to use three connections: one for index metadata and two
for data exchange.
- The following platforms unfortunately no longer get prebuilt binaries for
download at syncthing.net and on GitHub, due to complexities related to
cross compilation with SQLite:
- dragonfly/amd64
- solaris/amd64
- linux/ppc64
- netbsd/*
- openbsd/386 and openbsd/arm
- windows/arm
- The handling of conflict resolution involving deleted files has changed. A
delete can now be the winning outcome of conflict resolution, resulting in
the deleted file being moved to a conflict copy.

What's Changed
Fixes
- fix(beacon): don't join multicast groups on non-multicast interfaces (fixes #10497) by @marbens-arch in #10498

- build: fix hash failure by limiting globbing by @calmh in #10505
- chore: tweak pull retry logic by @calmh in #10491
Full Changelog: v2.0.12...v2.0.13

Major changes in 2.0
- Database backend switched from LevelDB to SQLite. There is a migration on
first launch which can be lengthy for larger setups. The new database is
easier to understand and maintain and, hopefully, less buggy.
- The logging format has changed to use structured log entries (a message
plus several key-value pairs). Additionally, we can now control the log
level per package, and a new log level WARNING has been inserted between
INFO and ERROR (which was previously known as WARNING...). The INFO level
has become more verbose, indicating the sync actions taken by Syncthing. A
new command line flag --log-level sets the default log level for all
packages, and the STTRACE environment variable and GUI has been updated
to set log levels per package. The --verbose and --logflags command
line options have been removed and will be ignored if given.
- Deleted items are no longer kept forever in the database, instead they are
forgotten after fifteen months. If your use case require deletes to take
effect after more than a fifteen month delay, set the
--db-delete-retention-interval command line option or corresponding
environment variable to zero, or a longer time interval of your choosing.
- Modernised command line options parsing. Old single-dash long options are
no longer supported, e.g. -home must be given as --home. Some options
have been renamed, others have become subcommands. All serve options are
now also accepted as environment variables. See syncthing --help and
syncthing serve --help for details.
- Rolling hash detection of shifted data is no longer supported as this
effectively never helped. Instead, scanning and syncing is faster and more
efficient without it.
- A "default folder" is no longer created on first startup.
- Multiple connections are now used by default between v2 devices. The new
default value is to use three connections: one for index metadata and two
for data exchange.
- The following platforms unfortunately no longer get prebuilt binaries for
download at syncthing.net and on GitHub, due to complexities related to
cross compilation with SQLite:
- dragonfly/amd64
- solaris/amd64
- linux/ppc64
- netbsd/*

Major changes in 2.0
- Database backend switched from LevelDB to SQLite. There is a migration on first launch which can be lengthy for larger setups. The new database is easier to understand and maintain and, hopefully, less buggy.
- The logging format has changed to use structured log entries (a message plus several key-value pairs). Additionally, we can now control the log level per package, and a new log level WARNING has been inserted between INFO and ERROR (which was previously known as WARNING...). The INFO level has become more verbose, indicating the sync actions taken by Syncthing. A new command line flag `--log-level` sets the default log level for all packages, and the `STTRACE` environment variable and GUI has been updated to set log levels per package. The `--verbose` and `--logflags` command line options have been removed and will be ignored if given.
- Deleted items are no longer kept forever in the database, instead they are forgotten after fifteen months. If your use case require deletes to take effect after more than a fifteen month delay, set the `--db-delete-retention-interval` command line option or corresponding environment variable to zero, or a longer time interval of your choosing.
- Modernised command line options parsing. Old single-dash long options are no longer supported, e.g. `-home` must be given as `--home`. Some options have been renamed, others have become subcommands. All serve options are now also accepted as environment variables. See `syncthing --help` and `syncthing serve --help` for details.
- Rolling hash detection of shifted data is no longer supported as this effectively never helped. Instead, scanning and syncing is faster and more efficient without it.
- A "default folder" is no longer created on first startup.
- Multiple connections are now used by default between v2 devices. The new default value is to use three connections: one for index metadata and two for data exchange.
- The following platforms unfortunately no longer get prebuilt binaries for download at syncthing.net and on GitHub, due to complexities related to cross compilation with SQLite:
- dragonfly/amd64
- illumos/amd64 and solaris/amd64
- linux/ppc64
- netbsd/*
- openbsd/386 and openbsd/arm
- windows/arm
- The handling of conflict resolution involving deleted files has changed. A delete can now be the winning outcome of conflict resolution, resulting in the deleted file being moved to a conflict copy.

This release is also available as:
- APT repository: https://apt.syncthing.net/
- Docker image: `docker.io/syncthing/syncthing:2.0.3` or `ghcr.io/syncthing/syncthing:2.0.3` (`{docker,ghcr}.io/syncthing/syncthing:2` to follow just the major version)
