### 2023-11-24 - Version 3.44.2

> The CLI fix in version 3.44.1 introduced a new bug, which is fixed by patch release 3.44.2. Version 3.44.2 also fixes an FTS5 problem that was found by a fuzzer just minutes after the 3.44.1 release.

### 2023-11-22 - Version 3.44.1

> Version 3.44.1 is a patch release that fixes various obscure bugs. There is no need to upgrade, unless you are having problems with a prior release.

### 2023-11-01 - Version 3.44.0

> Version 3.44.0 is new enhancement release of SQLite.

> It has only been 69 days since the previous major release (3.43.0). The original plan was for version 3.44.0 to occur at a spacing of approximately 120 days from the prior release. However, the code accumulated so many important enhancements that is seemed better to accelerate the release of 3.44.0, thus getting those enhancements into circulation. This means that some enhancements that where originally planned to be in 3.44.0 have been deferred until subsequent releases.

### 2023-10-10 - Version 3.43.2

> Version 3.43.2 is a patch release that fixes a few small inaccuracies in version 3.43.0 and 3.43.1.

### 2023-09-11 - Version 3.43.1

> Version 3.43.1 is a patch release that fixes a few small inaccuracies that were discovered in the the 3.43.0 and/or 3.42.0 releases after the 3.43.0 release was published.

### 2023-08-24 - Version 3.43.0

> Version 3.43.0 is a routine enhancement release of SQLite. Key enhancements in this release include added support for Contentless-Delete FTS5 Indexes, and performance improvements in JSON processing. See the change log for details.

### 2023-05-16 - Version 3.42.0

> Version 3.42.0 is a routine enhancement release of SQLite. Key enhancements in this release are added support for JSON5 and the FTS5 secure-delete command. See the change log for a summary of all enhancements in this release.

### 2023-03-22 - Version 3.41.2

> Version 3.41.2 is a patch release that fixes multiple fuzzer-found problems in prior releases. The worst problems include reads (not writes) past the end of a buffer. Upgrading is recommended.

### 2023-03-10 - Version 3.41.1

> Version 3.41.1 is a patch release that fixes various obscure problems found in 3.41.0 and reported by users. Upgrading is optional.

### 2023-02-21 - Version 3.41.0

> Version 3.41.0 is a routine enhancement release.

### 2022-12-28 - Version 3.40.1

> Version 3.40.1 is a patch release that fixes some obscure problems in version 3.40.0. The problems fixed have no impact on most applications. Upgrading is only necessary if you encounter problems.

> The two most important fixes are these:

> - Fix the safe command-line option on the CLI so that it correctly disallows functions with side-effects. This is a bug in the CLI — not a bug in the SQLite library — and it only affects the --safe command-line option, making that option less than fully "safe". As the number of systems that use the --safe command-line option in the CLI is approximately zero, this is not considered an important bug. However, a third-party wrote a CVE against it which caused considerable angst among maintainers, so it seems good to get the fix into circulation sooner rather than wait on the next major release.

> - The optional memsys5 memory allocator picked up a bug that might put it into an infinite loop for very large (500MiB) allocations. Almost all systems use their native memory allocator, not memsys5. Memsys5 is only used if SQLite is compiled using SQLITE_ENABLE_MEMSYS5 and then initialized using sqlite3_config(SQLITE_CONFIG_HEAP). Very, very few systems do this, and so the problem is not considered to be serious.

> See the branch-3.40 timeline for a complete listing of changes that have gone into this patch release.

### 2022-11-16 - Version 3.40.0

> Version 3.40.0 is a new feature release of SQLite. See the change log for details. Key enhancements in this release include:

> 1. Official support for compiling SQLite to WASM and running it in a web browser.

> 2. New and improved recovery extension for extracting data from corrupted database files.

> This release also includes performance enhancements and improvements to the query planner.

> A psychological milestone: The performance benchmark that the SQLite developers have used for many years has for the first time dropped below 1 billion CPU cycles (measured using cachegrind) when run in WAL mode. This is less than half the number of CPU cycles used as recently as 8 years ago. (The graph below shows SQLite using a rollback journal which uses fewer CPU cycles at the expense of extra I/O. The benchmark passed through the 1 billion cycle barrier for rollback journals for the previous release.)

### 2022-09-29 - Version 3.39.4

> Version 3.39.4 is a security release that addresses a single long-standing problem in the FTS3 extension. An attacker who is able to execute arbitrary SQL statements and who can create a corrupt database that is 2GB or larger in size might be able to trick FTS3 into overflowing an integer used to size a memory allocation, causing the allocation to be too small and ultimately resulting in a buffer overrun. The release also includes fixes for other obscure weaknesses, as described in the release notes.

### 2022-09-05 - Version 3.39.3

> Version 3.39.3 is a patch release that fixes a few obscure problems in the 3.39.0 release. See the release notes for details.

### 2022-07-21 - Version 3.39.2

> Version 3.39.2 is a security release that addresses multiple long-standing issues in SQLite. The most severe problem is identified by CVE-2022-35737. That issue is associated with the auxiliary C-language APIs of SQLite and cannot be reached using SQL or database inputs, and hence is unlikely to affect your application. Nevertheless, upgrading is recommended. The other issues are comparatively minor. This release also fixes a performance regression that appeared in version 3.39.0 that might affect some multi-way joins that use LEFT JOIN.

### 2022-07-13 - Version 3.39.1

> Version 3.39.1 is a patch release that fixes a few minor problem in version 3.39.0. Upgrading is optional.

### 2022-06-25 - Version 3.39.0

> Version 3.39.0 is regular maintenance release of SQLite. The key enhancement in this release is added support for RIGHT and FULL JOIN. There are other language and performance enhancements as well — see the release notes for details.

### 2022-05-06 - Version 3.38.5

> The 3.38.4 patch release included a minor change to the CLI source code that did not work. The release manager only ran a subset of the normal release tests, and hence did not catch the problem. As a result, the CLI will segfault when using columnar output modes in version 3.38.4. This blunder did not affect the core SQLite library. It only affected the CLI.

> Take-away lesson: Always run all of your tests prior to a release - even a trival patch release. Always.

> The 3.38.5 patch release fixes the 3.38.4 blunder.

### 2022-05-04 - Version 3.38.4

> Another user-discovered problem in the new Bloom filter optimization is fixed in this patch release. Without the fix, it is possible for a multi-way join that uses a Bloom filters for two or more tables in the join to enter an infinite loop if the key constraint on one of those tables contains a NULL value.

### 2022-04-27 - Version 3.38.3

> Version 3.38.3 fixes a bug in the automatic-index and Bloom filter construction logic that might cause SQLite to be overly aggressive in the use of ON clause constraints, resulting in an incorrect automatic-index or Bloom filter that excludes some valid rows from output. The bug was introduced in version 3.38.0. Other minor changes were tossed in to complete the patch.

### 2022-03-26 - Version 3.38.2

> Version 3.38.2 fixes another bug in the new Bloom filter optimization that might cause incorrect answers for a LEFT JOIN that has an IS NULL constraint on the right-hand table.

### 2022-03-12 - Version 3.38.1

> Version 3.38.1 fixes a pair of bugs in the Bloom filter optimization that was introduced in version 3.38.0. These bugs might cause incorrect answers for some obscure queries. Various other minor problems and documentation typos were fixed at the same time.

### 2022-02-22 - Version 3.38.0

> Version 3.38.0 is a routine maintenance release of SQLite. There are various minor enhancements and about a 0.5% reduction in the number of CPU cycles used. See the release notes for more detail.

### 2022-01-06 - Version 3.37.2

> Version 3.37.2 fixes a database corruption bug. You are encouraged to upgrade, especially if you are using SAVEPOINT.

> The problem first appeared in version 3.35.0 (2021-03-12) and affects all subsequent releases through 3.37.1. If temporary files are store in memory (which is not the default behavior, but is sometimes selected by applications using either -DSQLITE_TEMP_STORE or PRAGMA temp_store) and if a SAVEPOINT is rolled back and then subsequent changes within the same transaction are committed, the database file might (with low but non-zero probability) go corrupt.

### 2021-12-30 - Version 3.37.1

> Version 3.37.1 fixes a bug in the UPSERT logic, introduced by the UPSERT enhancements of version 3.35.0, that can cause incorrect byte-code to be generated in some cases, resulting in an infinite loop in the byte code, or a NULL-pointer dereference. This patch release also fixes some other minor problems with assert() statements and in the CLI.

### 2021-11-27 - Version 3.37.0

> Version 3.37.0 is a routine maintenance release of SQLite. The biggest new feature in this release is support for STRICT tables. Other enhancements are described in the release notes.

### 2021-06-18 - Version 3.36.0

> Version 3.36.0 is a routine maintenance release of SQLite. There are no new major features, only incremental improvements to existing features and small performance improvements.

### 2021-04-19 - Patch release 3.35.5

> The new ALTER TABLE DROP COLUMN capability that was added in the 3.35.0 release contained a bug that might cause the table content to go corrupt when the table was rewritten to remove the dropped column. Fixed by this patch.

### 2021-04-02 - Patch release 3.35.4

> Version 3.35.4 is yet another patch release to fix obscure problems in features associated with the 3.35.0.

### 2021-03-26 - Patch release 3.35.3

> Version 3.35.3 contains patches for a handful of minor problems discovered in prior releases.

### 2021-03-17 - Patch release 3.35.2

> Version 3.35.2 is a small patch release to fix some minor problems that were discovered shortly after the 3.35.1 release.

### 2021-03-15 - Patch release 3.35.1

> A user discovered an issue with the new DROP COLUMN capability in version 3.35.0, and so version 3.35.1 was created to fix it. No need to upgrade if you are not using DROP COLUMN.

### 2021-03-12 - Release 3.35.0

> SQLite version 3.35.0 is a routine maintenance release. This release adds a number of new language features, including support for ALTER TABLE DROP COLUMN, built-in math functions, generalized UPSERT, and the MATERIALIZED hint on common table expressions. There are also query planner optimizations and incremental CLI improvements.

### 2020-01-20 - Release 3.34.1

> SQLite version 3.34.1 is a patch releases that fixes a possible use-after-free bug that can be provoked by malicious SQL. Other minor issues in extensions and documentation are also fixed.

### 2020-12-01 - Release 3.34.0

> SQLite version 3.34.0 is a routine maintenance release. This release adds incremental improvements to performance and features, including enhancements to the query planner, multiple recursive SELECTS in recursive common table expressions, and better error messages from CHECK constraint failures. See the change log for details.

### 2020-08-14 - Release 3.33.0

> SQLite version 3.33.0 is a routine maintenance release. This release features added support for "UPDATE FROM" following the PostgreSQL syntax, and a doubling of the maximum database size to 281 TB, as well as many other improvements. See the change log for details.

### 2020-06-18 - Release 3.32.3

> The 3.32.3 release is a patch release that contains fixes for various issues discovered by fuzzers. None of the issues fixed are likely to be encountered by applications that use SQLite in ordinary ways, though upgrading never hurts.

> Map of all changes since the 3.32.0 release: https://www.sqlite.org/src/timeline?p=version-3.32.3&bt=version-3.32.0

### 2020-06-04 - Release 3.32.2

> The 3.32.2 release is a one-line change relative to 3.32.1 that fixes a long-standing bug in the COMMIT command. Since version 3.17.0, if you were to retry a COMMIT command over and over after it returns SQLITE_BUSY, it might eventually report success, even though it was still blocked. This patch fixes the problem.

### 2020-05-25 - Release 3.32.1

> Grey-hats published information about two SQLite bugs approximately 24 hours after the release of version 3.32.0. These bugs enable maliciously crafted SQL to crash the process that is running SQLite. Both bugs are long-standing problems that affect releases prior to 3.32.0. The 3.32.1 release fixes both problems.

### 2020-05-22 - Release 3.32.0

> Version 3.32.0 is an ordinary maintenance release of SQLite. This release features the ability to run an approximate ANALYZE to gather database statistics for use by the query planner, without having to scan every row of every index. See the change log for additional enhancements and improvements.

### 2020-01-27 - Release 3.31.1

> Applications that use SQLite should only interface with SQLite through the officially published APIs. Applications should not depend upon or use the internal data structures of SQLite as those structures might change from one release to another. However, there is a popular application that does depend on the details of the internal layout of data in an internal SQLite data structure, and those details changed in version 3.31.0, breaking the application. This is, technically, a bug in the application, not in SQLite. But it is within the power of SQLite to fix it, by reverting the internal data structure change, and so that is what we have done for the 3.31.1 release.

### 2020-01-22 - Release 3.31.0

> Version 3.31.0 is an ordinary maintenance release of SQLite. This release features the ability to define generated columns for tables as well as many other enhancements. See the change log for additional information.

### 2019-10-11 - Release 3.30.1

> Version 3.30.1 is a bug-fix release that addresses a problem that can occur when an aggregate function in a nested query makes use of the new FILTER clause capability. Some addition patches for various obscure issues are also included, for completeness.

### 2019-10-04 - Release 3.30.0

> Version 3.30.0 is a regularly scheduled maintenance release of SQLite containing miscellaneous performance and feature enhancements. This release adds support fo the NULLS FIRST and NULLS LAST clauses on ORDER BY statements and the addition of FILTER clauses on all aggregate functions. See the change log for details.

### 2019-07-10 - Release 3.29.0

> Version 3.29.0 is a regularly scheduled maintenance release of SQLite containing miscellaneous performance and feature enhancements. See the change log for details.

> Beginning with this release, the double-quoted string literal misfeature is deprecated. The misfeature is still enabled by default, for legacy compatibility, however developers are encouraged to disable it at compile-time using the -DSQLITE_DQS=0 option, or at run-time using the SQLITE_DBCONFIG_DQS_DML and SQLITE_DBCONFIG_DQS_DDL actions to the sqlite3_db_config() interface. This is especially true for double-quoted string literals in CREATE TABLE and CREATE INDEX statements, as those elements can cause unexpected problems following an ALTER TABLE. See ticket 9b78184be266fd70 for an example.

### 2019-04-16 - Release 3.28.0

> Version 3.28.0 is a regularly scheduled maintenance release of SQLite containing miscellaneous performance and feature enhancements. See the change log for details.

> This release fixes an obscure security issue. Applications using older versions of SQLite may be vulnerable if

> 1. SQLite is compiled with certain optional extensions enabled, and
> 2. the attacker is able to inject arbitrary SQL.
> We are not aware of any applications that are vulnerable to this problem. On the other hand, we do not know about every application that uses SQLite. If your application allows unauthenticated users on the internet (and hence potential attackers) to run arbitrary SQL and if you build SQLite with any of the optional extensions enabled, then you should take this upgrade at your earliest opportunity.

> For further information about improving SQLite's robustness in internet-facing applications, see the our security recommendations.

### 2019-02-25 - Release 3.27.2

> Version 3.27.2 is a patch release that fixes a two bugs and various documentation errors found in the version 3.27.1. The changes from version 3.27.1 and 3.27.0 are minimal.

### 2019-02-08 - Release 3.27.1

> After release 3.27.0 was tagged, but before the build could be completed and uploaded, a long-standing bug in the query optimizer was reported via System.Data.SQLite. Since people will be upgrading anyhow, we decided publish the fix for this newly discovered problems right away. Hence, 3.27.1 was released less than 24 hours after 3.27.0.

> It would have been better if the query optimizer bug had come to our attention one day earlier, so that we could have incorporated a fix into 3.27.0, but sometimes that's the way things go.

### 2019-02-07 - Release 3.27.0

> SQLite version 3.27.0 is a routine maintenance release with various performance and feature enhancements. See the release notes for details.

### 2018-12-01 - Release 3.26.0

> SQLite version 3.26.0 is a routine maintenance release with various performance and feature enhancements. See the release notes for details.

### 2018-11-05 - Release 3.25.3

> SQLite version 3.25.3 is a third patch against 3.25.0 that fixes various problems that have come to light and which seem serious enough to justify a patch.

### 2018-09-25 - Release 3.25.2

> SQLite version 3.25.2 is another patch against 3.25.0 that fixes still more problems associated with the new window function feature and the ALTER TABLE enhancements. Of particular note is the new PRAGMA legacy_alter_table=ON command, which causes the ALTER TABLE RENAME command to behave in the same goofy way that it did before the enhancements found in version 3.25.0 → references to renamed tables that are inside the bodies of triggers and views are not updated. The legacy behavior is arguably a bug, but some programs depend on the older buggy behavior. The 3.25.2 release also contains a fix to window function processing for VIEWs. There also a slew of other minor fixes that affect obscure compile-time options. See the Fossil Timeline for details.

### 2018-09-18 - Release 3.25.1

> SQLite version 3.25.1 is a patch against version 3.25.0 that contains two one-line fixes for bug that were introduced in version 3.25.0. See the change log for details. Upgrading from 3.25.0 is recommended.

### 2018-09-15 - Release 3.25.0

> SQLite version 3.25.0 is a regularly scheduled maintenance release. Two big enhancements in this release:

> 1. Support for window functions was added, using the PostgreSQL documentation as the baseline.

> 2. The ALTER TABLE command was enhanced to support renaming of columns, and so that column and table renames are propagated into trigger bodies and views.

> In addition, there are various performance enhancements and minor fixes.

> One bug of note is ticket 9936b2fa443fec which describes a hard-to-reach condition where the ORDER BY LIMIT optimization might cause an infinite loop during query evaluation. This ticket raised a lot of concern on HackerNews and Reddit, probably due to my choice of the ticket title. "Infinite Loop" sounds scary. But I argue that the bug isn't really all that bad in that it is very difficult to reach, will show up during testing (rather than magically appearing after a product is deployed), does not cause any data loss, and does not return an incorrect result. It was an important error, but not nearly as dire as many people interpreted it to be. And, in any event, it is fixed now.

### 2018-06-04 - Release 3.24.0

> SQLite version 3.24.0 is a regularly scheduled maintenance release. Highlights of this release include support for PostgreSQL-style UPSERT and improved performance, especially for ORDER BY LIMIT queries.

### 2018-04-10 - Release 3.23.1

> The version 3.23.1 release fixes a bug in the new LEFT JOIN strength reduction optimization added to version 3.23.0. A few other minor and obscure fixes were also inserted, as well as a small performance optimization. Code changes relative to version 3.23.0 are minimal.

### 2018-04-02 - Release 3.23.0

> The version 3.23.0 release is a regularly scheduled maintenance release. See the change log for a list of enhancements and bug fixes.

### 2018-01-22 - Release 3.22.0

> The version 3.22.0 release is a regularly scheduled maintenance release. There are many minor, though interesting, enhancements in this release. See the change log for details.

### 2017-10-24 - Release 3.21.0

> The version 3.21.0 release is a regularly scheduled maintenance release. There are lots of enhancements in this release. See the change log for details.

### 2017-08-24 - Release 3.20.1

> The version 3.20.1 patch release changes two lines of code in the sqlite3_result_pointer() interface in order to fix a rare memory leak. There are no other changes relative to version 3.20.0.

### 2017-08-01 - Release 3.20.0

> SQLite version 3.20.0 is a regularly scheduled maintenance release of SQLite.

> This release contains many minor enhancements, including:

> - Several new extensions
> - Enhancements to the "sqlite3.exe" command-line shell
> - Query planner enhancements
> - Miscellaneous code optimizations for improved performance
> - Fixes for some obscure bugs

> See the release notes for more information.

### 2017-06-17 - Release 3.18.2

> SQLite version 3.18.2 is another backport of a bug fix found in SQLite version 3.19.0, specifically the fix for ticket 61fe9745. Changes against version 3.18.0 are minimal.

### 2017-06-16 - Release 3.18.1

> SQLite version 3.18.1 is a bug-fix release against version 3.18.0 that fixes the auto_vacuum corruption bug described in ticket fda22108. This release was created for users who need that bug fix but do not yet want to upgrade to version 3.19.3.

### 2017-06-08 - Release 3.19.3

> Version 3.19.3 is an emergency patch release to fix a bug in auto_vacuum logic that can lead to database corruption. The bug was introduced in version 3.16.0 (2017-01-02). Though the bug is obscure and rarely encountered, upgrading is recommended for all users, and especially for users who turn on auto_vacuum.

### 2017-05-25 - Release 3.19.2

> Still more problems have been found in the LEFT JOIN flattening optimization that was added in the 3.19.0 release. This patch release fixes all known issues with that optimization and adds new test cases. Hopefully this will be the last patch.

### 2017-05-24 - Release 3.19.1

> One of the new query planner optimizations in the 3.19.0 release contained bugs. The 3.19.1 patch release fixes them.

> Beginning with 3.19.0, subqueries and views on the right-hand side of a LEFT JOIN operator could sometimes be flattened into the main query. The new optimization worked well for all of the test cases that the developers devised, and for millions of legacy test cases, but once 3.19.0 was released, users found some other cases where the optimization failed. Ticket cad1ab4cb7b0fc344 contains examples.

> These problems exist only in 3.19.0. Users of SQLite 3.19.0 should upgrade, but users of all prior versions of SQLite are safe.

### 2017-05-22 - Release 3.19.0

> SQLite version 3.19.0 is a regularly scheduled maintenance release.

> The emphasis on this release is improvements to the query planner. There are also some obscure bug fixes. There is no reason to upgrade unless you are having problems with a prior release.

### 2017-03-30 - Release 3.18.0

> SQLite version 3.18.0 is a regularly scheduled maintenance release.

> This release features an initial implementation the "PRAGMA optimize" command. This command can now be used to cause ANALYZE to be run on an as-needed basis. Applications should invoke "PRAGMA optimize" just before closing the database connection. The "PRAGMA optimize" statement will likely be enhanced to do other kinds of automated database maintenance in future releases.

> The Fossil version control system that is used to manage the SQLite project has been upgraded to use SHA3-256 hashes instead of SHA1. Therefore, the version identifications for SQLite now show a 64-hex-digit SHA3-256 hash rather than the 40-hex-digit SHA1 hash.

> See the change log for other enhancements and optimizations in this release.

### 2017-02-13 - Release 3.17.0

> SQLite version 3.17.0 is a regularly scheduled maintenance release.

> Most of the changes in this release are performance optimizations. Optimizations to the R-Tree extension are especially noticeable.

> In this release, the default size of the lookaside buffer allocated for each database connection is increased from 64,000 to 120,000 bytes. This provides improved performance on many common workloads in exchange for a small increase in memory usage. Applications that value a small memory footprint over raw speed can change the lookaside buffer size back to its old value (or to zero) using the SQLITE_DEFAULT_LOOKASIDE compile-time option, or the sqlite3_config(SQLITE_CONFIG_LOOKASIDE) start-time setting, or the sqlite3_db_config(SQLITE_DBCONFIG_LOOKASIDE) run-time setting.

### 2017-01-06 - Release 3.16.2

> One of the performance optimizations added in 3.16.0 caused triggers and foreign keys to malfunction for the REPLACE statement on WITHOUT ROWID tables that lack secondary indexes. This patch release fixes the problem. See ticket 30027b613b4 for details.

### 2017-01-03 - Release 3.16.1

> SQLite version 3.16.1 fixes a bug in the row-value logic for UPDATE statements inside of triggers. The bug has been there since row-values were added by release 3.15.0, but was not discovered until just a few minutes after the 3.16.0 release was published, and so it was not fixed by 3.16.0. This patch release is version 3.16.0 with the row-value bug fix.

### 2017-01-02 - Release 3.16.0

> SQLite version 3.16.0 is a regularly schedule maintenance release.

> This release includes many microoptimizations that collectively reduce the CPU cycle count by about 9%, add there have been important enhancements to the command-line shell.

> Support for PRAGMA functions is added, so that many pragma statements can be used as part of a larger SQL query. This is considered an experimental feature. We do not anticipate any changes to the PRAGMA function interface, but will keep continue to call this interface "experimental" for a few release cycles in case unforeseen issues arise.

> See the change log for other enhancements.

### 2016-11-28 - Release 3.15.2

> SQLite version 3.15.2 is a bug-fix patch release that fixes several minor issues in the 3.15.0 and 3.15.1 releases.

### 2016-11-04 - Release 3.15.1

> SQLite version 3.15.1 is a bug-fix patch release that fixes some minor issues in the 3.15.0 release.

### 2016-10-14 - Release 3.15.0

> SQLite version 3.15.0 is a regularly scheduled maintenance release. The key feature in this release is the added support for row values. There are also other enhancements and fixes for a number of obscure bugs.

> The 3.15.0 release uses about 7% fewer CPU cycles than 3.14.2. Most of the improvement in this release is in the SQL parser, query planner, and byte-code generator (the front-end) corresponding to the sqlite3_prepare_v2() interface. Overall, version 3.15.0 uses about half as much CPU time as version 3.8.1 (2013-10-17). These performance measurements are made using the "speedtest1.c" workload on x64 compiled with gcc and -Os. Performance improvements may vary with different platforms and workloads.

### 2016-09-12 - Release 3.14.2

> SQLite version 3.14.2 fixes several obscure bugs and adds improved support for building SQLite using the STDCALL calling convention on 32-bit windows systems. Upgrading from versions 3.14 and 3.14.1 is optional.

### 2016-08-11 - Release 3.14.1

> SQLite version 3.14.1 adds a small patch to improve the performance of the pcache1TruncateUnsafe() routine for cases when the only a few pages on the end of the cache are being removed. This causes COMMITs to run faster when there is a very large page cache. Upgrading from version 3.14 is optional.

### 2016-08-08 - Release 3.14

> SQLite version 3.14 (the "π" release) is a regularly scheduled maintenance release containing performance enhancements, new features, and fixes for obscure bugs.

### 2016-05-18 - Release 3.13.0

> SQLite version 3.13.0 is a regularly schedule maintenance release containing performance enhancements and fixes for obscure bugs.

### 2016-04-18 - Release 3.12.2

> Yikes! The 3.12.0 and 3.12.1 releases contain a backwards compatibility bug! Tables that declare a column with type `"INTEGER" PRIMARY KEY` (where the datatype name INTEGER is quoted) generate an incompatible database file. The mistake came about because the developers have never thought to put a typename in quotes before, and so there was no documentation of that capability nor any tests. (There are tests now, though, of course.) Instances of quoting the datatype name are probably infrequent in the wild, so we do not expect the impact of this bug to be too severe. Upgrading is still strongly recommended.

> Fixes for three other minor issues were included in this patch release. The other issues would have normally been deferred until the next scheduled release, but since a patch release is being issued anyhow, they might as well be included.

### 2016-04-08 - Release 3.12.1

> SQLite version 3.12.1 is an emergency patch release to address a crash bug that snuck into version 3.12.0. Upgrading from version 3.12.0 is highly recommended.

> Another minor problem involving datatypes on view columns, and a query planner deficiency are fixed at the same time. These two issues did not justify a new release on their own, but since a release is being issued to deal with the crash bug, we included these other fixes for good measure.

### 2016-03-29 - Release 3.12.0

> SQLite version 3.12.0 is a regularly scheduled maintenance release. A notable change in this release is an increase in the default page size for newly created database files. There are also various performance improvements. See the change log for details.

### 2016-03-03 - Release 3.11.1

> SQLite version 3.11.1 is a patch release that fixes problems in the new FTS5 extension and increases a default setting in the spellfix1 extension, and implements enhancements to some of the Windows makefiles. The SQLite core is unchanged from 3.11.0. Upgrading is optional.

### 2016-02-15 - Release 3.11.0

> SQLite version 3.11.0 is a regularly scheduled maintenance release.

### 2016-01-20 - Release 3.10.2

> Yikes! An optimization attempt gone bad resulted in a bug in the LIKE operator which is fixed by this patch release. Three other minor but low-risk fixes are also included in the patch.

### 2016-01-14 - Release 3.10.1

> SQLite version 3.10.1 is a bug-fix release primarily targeting the fix for the query planner bug cb3aa0641d9a4 discovered by Mapscape. Also included is a minor API enhancement requested by the Firefox developers at Mozilla. The differences from version 3.10.0 are minimal.

### 2016-01-06 - Release 3.10.0

> SQLite version 3.10.0 is a regularly scheduled maintenance release.
