* Address [#448](https://github.com/seancorfield/honeysql/issues/448) by adding a new section with hints and tips for database-specific syntax and solutions.
* Fix [#478](https://github.com/seancorfield/honeysql/issues/478) by handling `:do-update-set` correctly in the `upsert` helper and by handling parameters correctly in the `:do-update-set` formatter.
* Fix [#476](https://github.com/seancorfield/honeysql/issues/476) by adding support for multiple arguments to `:raw`, essentially restoring 1.x functionality (while still allowing for embedded vectors as expressions, introduced in 2.x).
* Fix [#467](https://github.com/seancorfield/honeysql/issues/467) by allowing single keywords (symbols) as a short hand for a single-element sequence in more constructs via PR [#470](https://github.com/seancorfield/honeysql/pull/470) [@p-himik](https://github.com/p-himik).
* Fix [#465](https://github.com/seancorfield/honeysql/issues/465) to allow multiple columns in `:order-by` special syntax via PR [#468](https://github.com/seancorfield/honeysql/pull/468) [@p-himik](https://github.com/p-himik).
* Fix [#464](https://github.com/seancorfield/honeysql/issues/464) by adding an optional type argument to `:array` via PR [#469](https://github.com/seancorfield/honeysql/pull/469) [@p-himik](https://github.com/p-himik).
* Address [#462](https://github.com/seancorfield/honeysql/issues/462) by adding a note in the documentation for set operations, clarifying precedence issues.
* Fix [#461](https://github.com/seancorfield/honeysql/issues/461) -- a regression introduced in 2.4.979 -- by restricting unary operators to just `+`, `-`, and `~` (bitwise negation).
* Address [#456](https://github.com/seancorfield/honeysql/issues/456) by allowing `format` to handle expressions (like 1.x could) as well as statements. This should aid with migration from 1.x to 2.x.
* Address [#452](https://github.com/seancorfield/honeysql/pull/452) by adding `:replace-into` to the core SQL supported, instead of just for the MySQL and SQLite dialects (so the latter is not needed yet).
* Address [#445](https://github.com/seancorfield/honeysql/issues/445) and [#453](https://github.com/seancorfield/honeysql/issues/453) by adding key/constraint examples to `CREATE TABLE` docs.
* Fix `:cast` formatting when quoting is enabled, via PR [#443](https://github.com/seancorfield/honeysql/pull/443) [duddlf23](https://github.com/duddlf23).
* Fix [#441](https://github.com/seancorfield/honeysql/issues/441) by adding `:replace-into` to in-flight clause order (as well as registering it for the `:mysql` dialect).
* Fix [#433](https://github.com/seancorfield/honeysql/issues/433) by supporting additional `WITH` syntax, via PR [#432](https://github.com/seancorfield/honeysql/issues/432), [@MawiraIke](https://github.com/MawiraIke). _[Technically, this was in 2.4.947, but I kept the issue open while I wordsmithed the documentation]_
* Address [#405](https://github.com/seancorfield/honeysql/issues/405) by adding `:numbered` option, which can also be set globally using `set-options!`.
* Fix [#439](https://github.com/seancorfield/honeysql/issues/439) by rewriting how DDL options are processed; also fixes [#386](https://github.com/seancorfield/honeysql/issues/386) and [#437](https://github.com/seancorfield/honeysql/issues/437); **Whilst this is intended to be purely a bug fix, it has the potential to be a breaking change -- hence the version jump to 2.4!**
* Fix [#431](https://github.com/seancorfield/honeysql/issues/431) -- `WHERE false` differed between the DSL and the `where` helper.
* Address [#430](https://github.com/seancorfield/honeysql/issues/430) by treating `:'` as introducing a name that should be treated literally and not formatted as a SQL entity (which respects quoting, dot-splitting, etc); this effectively expands the "escape hatch" introduced via [#352](https://github.com/seancorfield/honeysql/issues/352) in 2.2.868. _Note that the function context behavior formats as a SQL entity, rather than the usual SQL "keyword", whereas this new context is a literal transcription rather than as a SQL entity!_
* Address [#425](https://github.com/seancorfield/honeysql/issues/425) by clarifying that `INTERVAL` as special syntax may be MySQL-specific and PostgreSQL uses difference syntax (because `INTERVAL` is a data type there).
* Address [#423](https://github.com/seancorfield/honeysql/issues/423) by supporting `DEFAULT` values and `DEFAULT` rows in `VALUES`.
* Address [#422](https://github.com/seancorfield/honeysql/issues/422) by auto-quoting unusual entity names when `:quoted` (and `:dialect`) are not specified, making HoneySQL more secure by default.
* Address [#413](https://github.com/seancorfield/honeysql/issues/413) by flagging a lack of `WHERE` clause for `DELETE`, `DELETE FROM`, and `UPDATE` when `:checking :basic` (or `:checking :strict`).
* Fix [#392](https://github.com/seancorfield/honeysql/issues/392) by adding support for `WITH` / (`NOT`) `MATERIALIZED` -- via PR [#420](https://github.com/seancorfield/honeysql/issues/420) [@robhanlon22](https://github.com/robhanlon22).
* Address [#418](https://github.com/seancorfield/honeysql/issues/418) by documenting a potential "gotcha" with multi-column `IN` expressions (a change from HoneySQL 1.x).
* Fix [#416](https://github.com/seancorfield/honeysql/issues/416) via PR [#417](https://github.com/seancorfield/honeysql/issues/417) from [@corasaurus-hex](https://github.com/corasaurus-hex) -- using the internal default state for the integrity assertion.
* Fix [#406](https://github.com/seancorfield/honeysql/issues/406) by adding `:alter-column` (which produces `MODIFY COLUMN` when the MySQL dialect is selected) and deprecating `:modify-column`.
* Address [#401](https://github.com/seancorfield/honeysql/issues/401) by adding `register-dialect!` and `get-dialect`, and also making `add-clause-before`, `strop`, and `upper-case` public so that new dialects are easier to construct.
* Address [#404](https://github.com/seancorfield/honeysql/issues/404) by documenting PostgreSQL's `ARRAY` constructor syntax and how to produce it.
* Address parts of [#403](https://github.com/seancorfield/honeysql/issues/403) by improving the documentation for `:array` and also improving the exception that was thrown when it was misused.
* Fix [#402](https://github.com/seancorfield/honeysql/issues/402) by allowing for expressions in `:insert-into` table.
* Fix [#398](https://github.com/seancorfield/honeysql/issues/398) by adding `honey.sql.pg-ops` namespace that registers PostgreSQL JSON and regex operators and provides symbolic names for "unwritable" operators (that contain `@`, `#`, or `~`).
* Address [#396](https://github.com/seancorfield/honeysql/issues/396) by throwing an exception if you try to cache a SQL statement that includes an `IN ()` expression, using a named parameter for the `IN` values.
* Address [#352](https://github.com/seancorfield/honeysql/issues/352) by treating `:'` as introducing a function name that should be formatted as a SQL entity (which respects quoting, dot-splitting, etc), rather than as a SQL "keyword".
* Address [#381](https://github.com/seancorfield/honeysql/issues/381) by adding `generic-helper-variadic` and `generic-helper-unary` to `honey.sql.helpers`.
* Address #281 by adding support for `SELECT * EXCEPT ..` and `SELECT * REPLACE ..` and `ARRAY<>` and `STRUCT<>` column types -- see [SQL Clause Reference - SELECT](https://cljdoc.org/d/com.github.seancorfield/honeysql/CURRENT/doc/getting-started/sql-clause-reference#select-select-distinct) and [SQL Clause Reference - DDL](https://cljdoc.org/d/com.github.seancorfield/honeysql/CURRENT/doc/getting-started/sql-clause-reference#ddl-clauses) respectively for more details.
* Fix #374 by removing aliasing of `:is` / `:is-not` -- this changes the behavior of `[:is-not :col true/false]` to be _correct_ and _include `NULL` values_. Using `:is` / `:is-not` with values that are not Boolean and not `nil` will produce invalid SQL.
* Address #369 by adding a big clarifying docstring to the `honey.sql.helpers` namespace pointing out that all helper functions are variadic, they are all `[& args]`, some have `:arglists` metadata to provide a more specific usage hint but those _all omit the optional first argument (the DSL hash map)_.
* Address #366 by introducing `:values-default-columns` option to control whether missing columns are treated as `NULL` or `DEFAULT` in `:values` clauses with sequences of hash maps.
* Fix #363 and #362 by aligning more closely the semantics of `:inline` syntax with the `:inline true` option. A side effect of this is that `[:inline [:param :foo]]` will now (correctly) inline the value of the parameter `:foo` whereas it previously produced `PARAMS SOURCE`. In addition, inlining has been extended to vector values, so `[:inline ["a" "b" "c"]]` will now produce `('a', 'b', 'c')` and `[:inline [:lift ["a" "b" "c"]]]` will now produce `['a', 'b', 'c']` which is what people seemed to expect (the behavior was previously unspecified).
* Fix #353 by correcting handling of strings used as SQL entities (such as table names); this was a regression introduced by a recent enhancement to `:create-table`.
* Fix #349 by adding an optional `:quoted` argument to `set-dialect!`.
* Fixes #344 by no longer dropping the qualifier on columns in a `SET` clause _for the `:mysql` dialect only_; the behavior is unchanged for all other dialects.
* Fix #338 by producing `OFFSET n ROWS` (or `ROW` if `n` is 1) if `:fetch` is present or `:sqlserver` dialect is specified; and by producing `FETCH NEXT n ROWS ONLY` (or `ROW` is `n` is 1; or `FIRST` instead of `NEXT` if `:offset` is not present).
* Fix #326 by allowing `ON`/`USING` to be optional and not dropping parameters on the floor.
* Fix #325 by making the `%` function call syntax respect `:quoted true` and/or `:dialect` options, and also allowing for qualified column names. (PR from @lognush)
* Fix #310 by adding support for `FILTER`, `WITHIN GROUP`, and `ORDER BY` (as an expression), from [nilenso/honeysql-postgres](https://github.com/nilenso/honeysql-postgres) 0.4.112. These are [Special Syntax](doc/special-syntax.md) and there are also helpers for `filter` and `within-group` -- so **be careful about referring in all of `honey.sql.helpers`** since it will now shadow `clojure.core/filter` (it already shadows `for`, `group-by`, `into`, `partition-by`, `set`, and `update`).
* Fix #317 by dropping qualifiers in `:set` clauses (just like we do with `:insert` columns). Note that you can still use explicit _dotted_ names if you want table qualification.
* Fix #312 by adding `:raw` as a clause. There is no helper function equivalent (because it would be ambiguous whether you meant a function form -- `[:raw ..]` -- or a clause form -- `{:raw ..}`; and for the same reason, there is no `nest` helper function since that also works as a clause and as a function/special syntax).
* Change coordinates to `com.github.seancorfield/honeysql` (although new versions will continue to be deployed to `seancorfield/honeysql` for a while -- see the [Clojars Verified Group Names policy](https://github.com/clojars/clojars-web/wiki/Verified-Group-Names)).
* Confirm the whole of the [nilenso/honeysql-postgres](https://github.com/nilenso/honeysql-postgres) is implemented out-of-the-box (#293, up to 0.3.104 -- see also #310 which brought parity up to 0.4.112).
* The coordinates for HoneySQL 2.x are `com.github.seancorfield/honeysql` so it can be added to a project that already uses HoneySQL 1.x without any conflicts, making it easier to migrate piecemeal from 1.x to 2.x.
* Fix #259 so column names are always unqualified in inserts. (@jrdoane)
* Fix #257 by adding support for `cross-join` / `merge-cross-join` / `:cross-join`. (@dcj)
* Switch dev/test pipeline to use CLI/`deps.edn` instead of Leiningen. Also add CI vi both CircleCI and GitHub Actions.
* Switch to MAJOR.MINOR.COMMITS versioning.
* Remove macrovich dependency as this is no longer needed with modern ClojureScript.
* Add mention of `next.jdbc` everywhere `clojure.java.jdbc` was mentioned.
* 0.9.10 -- 2020-03-06
* Fix #254#255 by adding support for `except`. (@ted-coakley-otm)
* Fix #253 properly by supporting `false` as well. (@ted-coakley-otm)
* Add cljs testing to `deps.edn`, also multi-version clj testing and new `readme` testing.
* 0.9.9 -- 2020-03-02
* Fix #253 by supporting non-sequential join expressions.
* 0.9.8 -- 2019-09-07
* Fix #249 by adding `honeysql.format/*namespace-as-table?*` and `:namespace-as-table?` option to `format`. (@seancorfield)
* 0.9.7 -- 2019-09-07
* Fix #248 by treating alias as "not a subquery" when generating SQL for it. (@seancorfield)
* Fix #247 by reverting #132 / #131 so the default behavior is friendlier for namespace-qualified keywords used for table and column names, but adds `honeysql.format/*allow-namespaced-names?*` to restore the previous behavior. A `:allow-namespaced-names?` option has been adding to `format` to set this more easily. (@seancorfield)
* Fix #235 by adding `set0` (`:set0`) and `set1` (`:set1`) variants of `sset` (`:set`) to support different placements of `SET` (before `FROM` or after `JOIN` respectively) that different databases require. See also #200. (@seancorfield)
* Fix #162 by adding `composite`/`:composite` constructor for values. (@seancorfield)
* Fix #139 by checking arguments to `columns`/`merge-columns` and throwing an exception if a single collection is supplied (instead of varargs). (@seancorfield)
* Fix #128 by adding `truncate` support. (@seancorfield)
* Fix #99 by adding a note to the first use of `select` in the README that column names can be keywords or symbols but not strings. (@seancorfield)
* 0.9.6 -- 2019-09-24
* Filter `nil` conditions out of `where`/`merge-where`. Fix #246. (@seancorfield)
* Fix reflection warning introduced in 0.9.5 (via PR #237).
* 0.9.5 -- 2019-09-07
* Support JDK11 (update Midje). PR #238. (@camsaul)
* Support Turkish user.language. PR #237. (@camsaul)
*`format-predicate` now accepts `parameterizer` as a named argument (default `:jdbc`) to match `format`. PR #234. (@glittershark)
* 0.9.4 -- 2018-10-01
*`#sql/inline nil` should produce `NULL`. Fix #221. (@seancorfield)
*`#sql/inline :kw` should produce `"kw"`. Fix #224 via PR #225. (@vincent-dm) Note: this introduces a new protocol, `Inlinable`, which controls inline value rendering, and changes the behavior of `#sql/inline :foo/bar` to produce just `"bar"` (where it was probably invalid SQL before).
* Alias expressions `[:col :alias]` are now checked to have exactly two elements. Fix #226. (@seancorfield)
* Allow `where` and `merge-where` to be given no predicates. Fix #228 and PR #230. (@seancorfield, @arichiardi)
*`as` alias is no longer split during quoting. Fix #221 and PR #231. (@gws)
