 Only accretive/fixative changes will be made from now on.
 
+* 1.3.next in progress
+  * Fix handling of `false` in `clob-column-reader` [#299](https://github.com/seancorfield/next-jdbc/issues/299) via PR [#300](https://github.com/seancorfield/next-jdbc/pull/300) from [@GAumala](https://github.com/GAumala)
+  * Switch tests to LazyTest via PR [#297](https://github.com/seancorfield/next-jdbc/pull/297).
+  * Update dev/test/build deps.
+
+* 1.3.1002 -- 2025-03-06
+  * Address [#296](https://github.com/seancorfield/next-jdbc/issues/296) by adding an explicit check (and `throw`) for `sql-params` in `next.jdbc` functions.
+  * Address [#295](https://github.com/seancorfield/next-jdbc/issues/295) by providing a way to tell `next.jdbc` that certain options should be passed "as-is" in the `Properties` object when creating a `Connection` -- `:next.jdbc/as-is-properties` accepts a sequence (or set) of keywords, identifying properties that should not be converted to strings.
+  * Fix [#181](https://github.com/seancorfield/next-jdbc/issues/181) (again!) by adding `Wrapped` protocol as a way for `DefaultOptions` and `SQLLogging` to consistently expose the underlying connectable, even when nested.
+
+* 1.3.994 -- 2025-01-28
+  * Fix [#293](https://github.com/seancorfield/next-jdbc/issues/293) by no longer `locking` on the `Connection` retrieved from a `DataSource`.
+  * Fix documentation examples of `execute-batch!` via PR [#292](https://github.com/seancorfield/next-jdbc/pull/292) from [@devurandom](https://github.com/devurandom).
+  * Update `java.data` to 1.3.113.
+  * Beef up bit/boolean tests and enable them for XTDB.
+
+* 1.3.981 -- 2024-12-13
+  * Address [#291](https://github.com/seancorfield/next-jdbc/issues/291) by adding an XTDB section to **Tips & Tricks**.
+  * Added XTDB as a supported database for testing via PR [#290](https://github.com/seancorfield/next-jdbc/pull/290). _Note: not all features are tested against XTDB due to several fundamental differences in architecture, mostly around primary key/generated keys and lack of DDL operations (since XTDB is schemaless)._
+  * Update dev/test dependencies.
+
+* 1.3.967 -- 2024-12-02
+  * Address [#288](https://github.com/seancorfield/next-jdbc/issues/288) by adding speculative support for `:dbtype "xtdb"`.
+  * Fix [#287](https://github.com/seancorfield/next-jdbc/issues/287) by merging user-supplied options over `:return-keys true`.
+  * Fix [#282](https://github.com/seancorfield/next-jdbc/issues/282) by tracking raw `Connection` objects for active TXs, which relaxes several of the conditions around nested transactions.
+  * Replace `assert` calls with proper validation, throwing `IllegalArgumentException` on failure.
+  * Removed (experimental) `:name-fn` option since the driver for it no longer exists (qualified columns names in XTDB).
+
+* 1.3.955 -- 2024-10-06
+  * Address [#285](https://github.com/seancorfield/next-jdbc/issues/285) by setting the default Clojure version to the earliest supported (1.10.3) to give a better hint to users.
+  * Update PostgreSQL **Tips & Tricks** example code to fix possible NPE. PR [#284](https://github.com/seancorfield/next-jdbc/pull/284) from [@ExNexu](https://github.com/ExNexu).
+  * Address [#283](https://github.com/seancorfield/next-jdbc/issues/283) by adding a note in the documentation, linking to the PostgreSQL bug report about `ANY(array)`.
+  * ~Address [#269](https://github.com/seancorfield/next-jdbc/issues/269) by adding `:name-fn` as an option (primarily for the SQL builder functions, but also for result set processing); the default is `clojure.core/name` but you can now use `next.jdbc.sql.builder/qualified-name` to preserve the qualifier.~ _[This was removed in 1.3.967 since XTDB no longer supports qualified column names]_
+  * Update testing deps; `docker-compose` => `docker compose`.
+
+* 1.3.939 -- 2024-05-17
+  * Fix [#280](https://github.com/seancorfield/next-jdbc/issues/280) by allowing `-` as well as `_` in `nav` foreign key names.
+  * Address [#279](https://github.com/seancorfield/next-jdbc/issues/279) by adding the missing documentation.
+  * Address [#278](https://github.com/seancorfield/next-jdbc/issues/278) by fixing link in options page.
+  * Update dev dependencies, including testing against Clojure 1.12 Alpha 11.
+
 * 1.3.925 -- 2024-03-15
   * Address [#275](https://github.com/seancorfield/next-jdbc/issues/275) by noting that PostgreSQL may perform additional SQL queries to produce table names used in qualified result set builders.
   * Address [#274](https://github.com/seancorfield/next-jdbc/issues/274) by adding `next.jdbc.sql/aggregate-by-keys` as a convenient wrapper around `find-by-keys` when you want just a single aggregate value back (such as `count`, `max`, etc).

 This project follows the version scheme MAJOR.MINOR.COMMITS where MAJOR and MINOR provide some relative indication of the size of the change, but do not follow semantic versioning. In general, all changes endeavor to be non-breaking (by moving to new names rather than by breaking existing names). COMMITS is an ever-increasing counter of commits since the beginning of this repository.
 
-> Note: every commit to the **develop** branch runs CI (GitHub Actions) and successful runs push a MAJOR.MINOR.999-SNAPSHOT build to Clojars so the very latest version of `next.jdbc` is always available either via that [snapshot on Clojars](https://clojars.org/com.github.seancorfield/next.jdbc) or via a git dependency on the latest SHA.

 ## Motivation
 
@@ -50,7 +51,7 @@ From a `DataSource`, either you or `next.jdbc` can create a `java.sql.Connection
 
 The primary SQL execution API in `next.jdbc` is:
 * `plan` -- yields an `IReduceInit` that, when reduced with an initial value, executes the SQL statement and then reduces over the `ResultSet` with as little overhead as possible.
-* `execute!` -- executes the SQL statement and produces a vector of realized hash maps, that use qualified keywords for the column names, of the form `:<table>/<column>`. If you join across multiple tables, the qualified keywords will reflect the originating tables for each of the columns. If the SQL produces named values that do not come from an associated table, a simple, unqualified keyword will be used. The realized hash maps returned by `execute!` are `Datafiable` and thus `Navigable` (see Clojure 1.10's `datafy` and `nav` functions, and tools like [Portal](https://github.com/djblue/portal), [Reveal](https://github.com/vlaaad/reveal), and Cognitect's REBL). Alternatively, you can specify `{:builder-fn rs/as-arrays}` and produce a vector with column names followed by vectors of row values. `rs/as-maps` is the default for `:builder-fn` but there are also `rs/as-unqualified-maps` and `rs/as-unqualified-arrays` if you want unqualified `:<column>` column names (and there are also lower-case variants of all of these).

The realized hash maps returned by `execute!` are `Datafiable` and thus `Navigable` (see Clojure 1.10's `datafy` and `nav` functions, and tools like [Portal](https://github.com/djblue/portal), [Reveal](https://github.com/vlaaad/reveal), and Nubank's Morse -- formerly Cognitect's REBL). Alternatively, you can specify `{:builder-fn rs/as-arrays}` and produce a vector with column names followed by vectors of row values. `rs/as-maps` is the default for `:builder-fn` but there are also `rs/as-unqualified-maps` and `rs/as-unqualified-arrays` if you want unqualified `:<column>` column names (and there are also lower-case variants of all of these).
 * `execute-one!` -- executes the SQL or DDL statement and produces a single realized hash map. The realized hash map returned by `execute-one!` is `Datafiable` and thus `Navigable`.
 
 In addition, there are API functions to create `PreparedStatement`s (`prepare`) from `Connection`s, which can be passed to `plan`, `execute!`, or `execute-one!`, and to run code inside a transaction (the `transact` function and the `with-transaction` macro).

 * `clojure.java.jdbc` implicitly allowed transactions to nest and just silently ignored the inner, nested transactions (so you only really had the top-level, outermost transaction); `next.jdbc` by default assumes you know what you are doing and so an inner (nested) transaction will commit or rollback the work done so far in outer transaction (and then when that outer transaction ends, the remaining work is rolled back or committed); `next.jdbc.transaction/*nested-tx*` is a dynamic var that can be bound to `:ignore` to get similar behavior to `clojure.java.jdbc`.

+## XTDB
+
+XTDB is a bitemporal, schemaless, document-oriented database that presents
+itself as a PostgreSQL-compatible database, in terms of JDBC. It has a number
+of SQL extensions, and some differences from common JDBC behavior. See
+its documentation for details:
+* [SQL Overview](https://docs.xtdb.com/quickstart/sql-overview.html)
+* [SQL Queries](https://docs.xtdb.com/reference/main/sql/queries.html)
+* [SQL Transactions/DML](https://docs.xtdb.com/reference/main/sql/txs.html)
+
+`next.jdbc` officially supports XTDB as of 1.3.981 but there are some caveats:
+* You can use `:dbtype "xtdb"` to identify XTDB as the database type.
+* You must specify `:dbname "xtdb"` in the db-spec hash map or JDBC URL.
+* XTDB does not support `.getTableName()` so you always get unqualified column names in result sets.
+* The primary key on all tables is `_id` and it must be specified in all `INSERT` operations (no auto-generated keys).
+* That means that `next.jdbc.sql/get-by-id` requires the 5-argument call, so that you can specify the `pk-name` as `:_id` and provide an options map.
+* If you want to use `next.jdbc`'s built-in `datafy` / `nav` functionality, you need to explicitly specify `:schema-opts {:pk "_id"}` to override the default assumption of `id` as the primary key.
+* DML operations (`INSERT`, `UPDATE`, and `DELETE`) are essentially asynchronous in XTDB and therefore can not return an accurate `next.jdbc/update-count` (so it is always 0).
+* `INSERT` operations do not return the inserted row (like PostgreSQL does) nor even the provided `_id` primary key.
+* That means that the `next.jdbc.defer` namespace functions do not work well with XTDB.
+* `next.jdbc.sql/insert-multi!` returns an empty vector for XTDB (since `INSERT` operations do not return keys or update counts).
+* The `next.jdbc.result-set/*-kebab-maps` functions (and associated `next.jdbc/*-kebab-opts` option maps) cause leading `_` to be stripped from column names and cannot be used with XTDB (this is inherent in the underlying library that `next.jdbc` relies on -- you can of course write your own custom result set builder function to handle this).
