+### DO NOT REPORT SECURITY ISSUES IN THIS ISSUE TRACKER
+
+Instead, contact security@syncthing.net directly - see
+https://syncthing.net/security.html for more information.
+
+### DO NOT POST SUPPORT REQUESTS OR GENERAL QUESTIONS IN THIS ISSUE TRACKER
+
+Please use the forum at https://forum.syncthing.net/ where a large number of
+helpful people hang out. This issue tracker is for reporting bugs or feature
+requests directly to the developers. Worst case you might get a short
+"that's a bug, please report it on GitHub" response on the forum, in which
+case we thank you for your patience and following our advice. :)
+
+### Please use the correct issue tracker
+
+If your problem relates to a Syncthing wrapper or [sub-project](https://github.com/syncthing) such as [Syncthing for Android](https://github.com/syncthing/syncthing-android/issues), [SyncTrayzor](https://github.com/canton7/synctrayzor) or the [documentation](https://github.com/syncthing/docs/issues), please use their respective issue trackers.
+
+### Does your log mention database corruption?
+
+If your Syncthing log reports panics because of database corruption it is most likely a fault with your system's storage or memory. Affected log entries will contain lines starting with `panic: leveldb`. You will need to delete the index database to clear this, by running `syncthing -reset-database`.
+
+### Please do post actual bug reports and feature requests.
+
+If your issue is a bug report, replace this boilerplate with a description
+of the problem, being sure to include at least:
+
+ - what happened,
+ - what you expected to happen instead, and
+ - any steps to reproduce the problem.

+screenshots as appropriate.

+its entirety.

+# The Syncthing Goals
+
+Syncthing is a **continuous file synchronization program**. It synchronizes
+files between two or more computers. We strive to fulfill the goals below.
+The goals are listed in order of importance, the most important one being
+the first.
+
+> "Syncing files" here is precise. It means we specifically exclude things
+> that are not files - calendar items, instant messages, and so on. If those
+> are in fact stored as files on disk, they can of course be synced as
+> files.
+
+Syncthing should be:
+
+### 1. Safe From Data Loss
+
+Protecting the user's data is paramount. We take every reasonable precaution
+to avoid corrupting the user's files.
+
+> This is the overriding goal, without which synchronizing files becomes
+> pointless. This means that we do not make unsafe trade offs for the sake
+> of performance or, in some cases, even usability.
+
+### 2. Secure Against Attackers
+
+Again, protecting the user's data is paramount. Regardless of our other
+goals we must never allow the user's data to be susceptible to eavesdropping
+or modification by unauthorized parties.
+
+> This should be understood in context. It is not necessarily reasonable to
+> expect Syncthing to be resistant against well equipped state level
+> attackers. We will however do our best. Note also that this is different
+> from anonymity which is not, currently, a goal.
+
+### 3. Easy to Use
+
+Syncthing should be approachable, understandable and inclusive.
+
+> Complex concepts and maths form the base of Syncthing's functionality.
+> This should nonetheless be abstracted or hidden to a degree where
+> Syncthing is usable by the general public.
+
+### 4. Automatic
+
+User interaction should be required only when absolutely necessary.
+
+> Specifically this means that changes to files are picked up without
+> prompting, conflicts are resolved without prompting and connections are
+> maintained without prompting. We only prompt the user when it is required
+> to fulfill one of the (overriding) Secure, Safe or Easy goals.
+
+### 5. Universally Available
+
+Syncthing should run on every common computer. We are mindful that the
+latest technology is not always available to any given individual.
+
+> Computers include desktops, laptops, servers, virtual machines, small
+> general purpose computers such as Raspberry Pis and, *where possible*,
+> tablets and phones. NAS appliances, toasters, cars, firearms, thermostats
+> and so on may include computing capabitilies but it is not our goal for
+> Syncthing to run smoothly on these devices.
+
+### 6. For Individuals
+
+Syncthing is primarily about empowering the individual user with safe,
+secure and easy to use file synchronization.
+
+> We acknowledge that it's also useful in an enterprise setting and include
+> functionality to support that. If this is in conflict with the
+> requirements of the individual, those will however take priority.
+
+### 7. Everything Else
+
+There are many things we care about that don't make it on to the list. It is
+fine to optimize for these values as well, as long as they are not in
+conflict with the stated goals above.
+
+> For example, performance is a thing we care about. We just don't care more
+> about it than safety, security, etc. Maintainability of the code base and
+> providing entertainment value for the maintainers are also things that
+> matter. It is understood that there are aspects of Syncthing that are
+> suboptimal or even in opposition with the goals above. However, we
+> continuously strive to align Syncthing more and more with these goals.

-Each encoded block begins with the varint-encoded length of the decoded data,
-followed by a sequence of chunks. Chunks begin and end on byte boundaries. The
-first byte of each chunk is broken into its 2 least and 6 most significant bits
-called l and m: l ranges in [0, 4) and m ranges in [0, 64). l is the chunk tag.
-Zero means a literal tag. All other values mean a copy tag.
-
-For literal tags:
-  - If m < 60, the next 1 + m bytes are literal bytes.
-  - Otherwise, let n be the little-endian unsigned integer denoted by the next
-    m - 59 bytes. The next 1 + n bytes after that are literal bytes.
-
-For copy tags, length bytes are copied from offset bytes ago, in the style of
-Lempel-Ziv compression algorithms. In particular:
-  - For l == 1, the offset ranges in [0, 1<<11) and the length in [4, 12).
-    The length is 4 + the low 3 bits of m. The high 3 bits of m form bits 8-10
-    of the offset. The next byte is bits 0-7 of the offset.
-  - For l == 2, the offset ranges in [0, 1<<16) and the length in [1, 65).
-    The length is 1 + m. The offset is the little-endian unsigned integer
-    denoted by the next 2 bytes.
-  - For l == 3, this tag is a legacy format that is no longer supported.

-ADVENTURE I. A SCANDAL IN BOHEMIA
-
-I.
-
-To Sherlock Holmes she is always THE woman. I have seldom heard
-him mention her under any other name. In his eyes she eclipses
-and predominates the whole of her sex. It was not that he felt
-any emotion akin to love for Irene Adler. All emotions, and that
-one particularly, were abhorrent to his cold, precise but
-admirably balanced mind. He was, I take it, the most perfect
-reasoning and observing machine that the world has seen, but as a
-lover he would have placed himself in a false position. He never
-spoke of the softer passions, save with a gibe and a sneer. They
-were admirable things for the observer--excellent for drawing the
-veil from men's motives and actions. But for the trained reasoner
-to admit such intrusions into his own delicate and finely
-adjusted temperament was to introduce a distracting factor which
-might throw a doubt upon all his mental results. Grit in a
-sensitive instrument, or a crack in one of his own high-power
-lenses, would not be more disturbing than a strong emotion in a
-nature such as his. And yet there was but one woman to him, and
-that woman was the late Irene Adler, of dubious and questionable
-memory.
-
-I had seen little of Holmes lately. My marriage had drifted us
-away from each other. My own complete happiness, and the
-home-centred interests which rise up around the man who first
-finds himself master of his own establishment, were sufficient to
-absorb all my attention, while Holmes, who loathed every form of
-society with his whole Bohemian soul, remained in our lodgings in
-Baker Street, buried among his old books, and alternating from
-week to week between cocaine and ambition, the drowsiness of the
-drug, and the fierce energy of his own keen nature. He was still,
-as ever, deeply attracted by the study of crime, and occupied his
-immense faculties and extraordinary powers of observation in
-following out those clues, and clearing up those mysteries which
-had been abandoned as hopeless by the official police. From time
-to time I heard some vague account of his doings: of his summons
-to Odessa in the case of the Trepoff murder, of his clearing up
-of the singular tragedy of the Atkinson brothers at Trincomalee,
-and finally of the mission which he had accomplished so
-delicately and successfully for the reigning family of Holland.
-Beyond these signs of his activity, however, which I merely
-shared with all the readers of the daily press, I knew little of
-my former friend and companion.

-License, supplemented by the additional permissions listed below.
-
-  0. Additional Definitions.
-
-  As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the GNU
-General Public License.
-
-  "The Library" refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-
-  An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
-  A "Combined Work" is a work produced by combining or linking an
-Application with the Library.  The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
-  The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
-  The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
-  1. Exception to Section 3 of the GNU GPL.
-
-  You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
-  2. Conveying Modified Versions.
-
-  If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
-   a) under this License, provided that you make a good faith effort to
-   ensure that, in the event an Application does not supply the
-   function or data, the facility still operates, and performs
-   whatever part of its purpose remains meaningful, or
-
-   b) under the GNU GPL, with none of the additional permissions of
-   this License applicable to that copy.
-
-  3. Object Code Incorporating Material from Library Header Files.
-
-  The object code form of an Application may incorporate material from
-a header file that is part of the Library.  You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
-   a) Give prominent notice with each copy of the object code that the
-   Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the object code with a copy of the GNU GPL and this license
-   document.
-
-  4. Combined Works.
-
-  You may convey a Combined Work under terms of your choice that,
-taken together, effectively do not restrict modification of the
-portions of the Library contained in the Combined Work and reverse
-engineering for debugging such modifications, if you also do each of
-the following:
-
-   a) Give prominent notice with each copy of the Combined Work that
-   the Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the Combined Work with a copy of the GNU GPL and this license
-   document.
-
-   c) For a Combined Work that displays copyright notices during
-   execution, include the copyright notice for the Library among
-   these notices, as well as a reference directing the user to the
-   copies of the GNU GPL and this license document.
-
-   d) Do one of the following:
-
-       0) Convey the Minimal Corresponding Source under the terms of this
-       License, and the Corresponding Application Code in a form
-       suitable for, and under terms that permit, the user to
-       recombine or relink the Application with a modified version of
-       the Linked Version to produce a modified Combined Work, in the
-       manner specified by section 6 of the GNU GPL for conveying
-       Corresponding Source.
-
-       1) Use a suitable shared library mechanism for linking with the
-       Library.  A suitable mechanism is one that (a) uses at run time
-       a copy of the Library already present on the user's computer
-       system, and (b) will operate properly with a modified version
-       of the Library that is interface-compatible with the Linked
-       Version.
-
-   e) Provide Installation Information, but only if you would otherwise
-   be required to provide such information under section 6 of the
-   GNU GPL, and only to the extent that such information is
-   necessary to install and execute a modified version of the
-   Combined Work produced by recombining or relinking the
-   Application with a modified version of the Linked Version. (If
-   you use option 4d0, the Installation Information must accompany
-   the Minimal Corresponding Source and Corresponding Application
-   Code. If you use option 4d1, you must provide the Installation
-   Information in the manner specified by section 6 of the GNU GPL
-   for conveying Corresponding Source.)
-
-  5. Combined Libraries.
-
-  You may place library facilities that are a work based on the
-Library side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
-   a) Accompany the combined library with a copy of the same work based
-   on the Library, uncombined with any other library facilities,
-   conveyed under the terms of this License.
-
-   b) Give prominent notice with the combined library that part of it
-   is a work based on the Library, and explaining where to find the
-   accompanying uncombined form of the same work.
-
-  6. Revised Versions of the GNU Lesser General Public License.
-
-  The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
-  Each version is given a distinguishing version number. If the
-Library as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
-  If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

-    import "github.com/juju/ratelimit"
-
-The ratelimit package provides an efficient token bucket implementation. See
-http://en.wikipedia.org/wiki/Token_bucket.
-
-## Usage
-
-#### func  Reader
-
-```go
-func Reader(r io.Reader, bucket *Bucket) io.Reader
-```
-Reader returns a reader that is rate limited by the given token bucket. Each
-token in the bucket represents one byte.
-
-#### func  Writer
-
-```go
-func Writer(w io.Writer, bucket *Bucket) io.Writer
-```
-Writer returns a reader that is rate limited by the given token bucket. Each
-token in the bucket represents one byte.
-
-#### type Bucket
-
-```go
-type Bucket struct {
-}
-```
-
-Bucket represents a token bucket that fills at a predetermined rate. Methods on
-Bucket may be called concurrently.
-
-#### func  NewBucket
-
-```go
-func NewBucket(fillInterval time.Duration, capacity int64) *Bucket
-```
-NewBucket returns a new token bucket that fills at the rate of one token every
-fillInterval, up to the given maximum capacity. Both arguments must be positive.
-The bucket is initially full.
-
-#### func  NewBucketWithQuantum
-
-```go
-func NewBucketWithQuantum(fillInterval time.Duration, capacity, quantum int64) *Bucket
-```
-NewBucketWithQuantum is similar to NewBucket, but allows the specification of
-the quantum size - quantum tokens are added every fillInterval.
-
-#### func  NewBucketWithRate
-
-```go
-func NewBucketWithRate(rate float64, capacity int64) *Bucket
-```
-NewBucketWithRate returns a token bucket that fills the bucket at the rate of
-rate tokens per second up to the given maximum capacity. Because of limited
-clock resolution, at high rates, the actual rate may be up to 1% different from
-the specified rate.
-
-#### func (*Bucket) Rate
-
-```go
-func (tb *Bucket) Rate() float64
-```
-Rate returns the fill rate of the bucket, in tokens per second.
-
-#### func (*Bucket) Take
-
-```go
-func (tb *Bucket) Take(count int64) time.Duration
-```
-Take takes count tokens from the bucket without blocking. It returns the time
-that the caller should wait until the tokens are actually available.
-
-Note that if the request is irrevocable - there is no way to return tokens to
-the bucket once this method commits us to taking them.
-
-#### func (*Bucket) TakeAvailable
-
-```go
-func (tb *Bucket) TakeAvailable(count int64) int64
-```
-TakeAvailable takes up to count immediately available tokens from the bucket. It
-returns the number of tokens removed, or zero if there are no available tokens.
-It does not block.
-
-#### func (*Bucket) TakeMaxDuration
-
-```go
-func (tb *Bucket) TakeMaxDuration(count int64, maxWait time.Duration) (time.Duration, bool)
-```
-TakeMaxDuration is like Take, except that it will only take tokens from the
-bucket if the wait time for the tokens is no greater than maxWait.
-
-If it would take longer than maxWait for the tokens to become available, it does
-nothing and reports false, otherwise it returns the time that the caller should
-wait until the tokens are actually available, and reports true.
-
-#### func (*Bucket) Wait
-
-```go
-func (tb *Bucket) Wait(count int64)
-```
-Wait takes count tokens from the bucket, waiting until they are available.
-
-#### func (*Bucket) WaitMaxDuration
-
-```go
-func (tb *Bucket) WaitMaxDuration(count int64, maxWait time.Duration) bool
-```
-WaitMaxDuration is like Wait except that it will only take tokens from the
-bucket if it needs to wait for no greater than maxWait. It reports whether any
-tokens have been removed from the bucket If no tokens have been removed, it
-returns immediately.
