## v3.135.0
* Added `topicoptions.WithWriterErrOnQueueFull(bool)` option for topic writer to make `Write` return `topicwriter.ErrQueueLimitExceed` immediately when the internal queue is full, instead of blocking. Useful for preventing OOM when the writer cannot keep up with produced messages.
* Un-deprecated `topicwriter.ErrQueueLimitExceed`: it is returned by `Write` when a writer is created with `topicoptions.WithWriterErrOnQueueFull(true)` and the internal queue is full.

## v3.134.2
* Fixed `table.Session.Execute` ignoring `options.WithCommit()` so transactions were not committed when the option was passed

* Fixed panic when topic writer is closed unexpectedly

## v3.128.3
* Fixed panic and `unsupported type` error when passing a nil pointer to a `json.Marshaler`-implementing type as a `database/sql` query parameter (`toType` now handles `json.Marshaler` and returns `types.JSON`, matching the existing `toValue` behaviour)

## v3.128.2
* Downgraded direct dependency `google.golang.org/grpc` to v1.78.0

## v3.128.1

## v3.127.5
* Fixed a bug in `ydb.WithNumericArgs` where the `-- origin query with numeric args replacement` comment was incorrectly prepended even when no `$N` placeholders were replaced in the query
* Fixed a bug where combining `ydb.WithPositionalArgs` and `ydb.WithNumericArgs` caused `ErrInconsistentArgs` when the query contained no `?` placeholders — `PositionalArgs` now passes args through unchanged when it has nothing to bind, regardless of registration order

## v3.127.4
* Stopped tracing `SessionDelete` in `tableService` spans adapter (no value for observability)

* Fixed a bug when sometimes in cases of context cancellation returner error was not `errors.Is(err, context.Canceled)`

## v3.126.5
* Invoke `OnWriterReceiveResult` trace callback when topic writer receives ack from server (enables client-side logging for sync write diagnostics)
* Added `ydb.WithCommitTxContext(ctx)` to request commit along with query execution in database/sql transactions

## v3.126.4
* Fixed a bug where the `internal/value.Any()` method was prematurely converting `*decimalValue` to `decimal.Decimal`, preventing users from implementing custom scanners that need to work with the underlying YDB value type.

## v3.126.3
* Allowed `TxControl` in `database/sql` transaction execution when TxControl equals TxControl on BeginTx

## v3.126.2
