<description>The {[project]} Releases detail each version of the software and lists the changes made in each version.</description>
<intro>
<text><backrest/> release numbers consist of two parts, major and minor. A major release <i>may</i> break compatibility with the prior major release, but <proper>v2</proper> releases are fully compatible with <proper>v1</proper> repositories and will accept all <proper>v1</proper> options. Minor releases can include bug fixes and features but do not change the repository format and strive to avoid changing options and naming.
Documentation for the <proper>v1</proper> release can be found <link url="{[backrest-url-base]}/1">here</link>.
The notes for a release may also contain <quote>Additional Notes</quote> but changes in this section are only to documentation or the test suite and have no direct impact on the <backrest/> codebase.</text>

<release-item>
<p>Allow any option to be set in an environment variable. This includes options that previously could only be specified on the command line, e.g. <br-option>stanza</br-option>, and secret options that could not be specified on the command-line, e.g. <br-option>repo1-s3-key-secret</br-option>.</p>

<p>Exclude temporary and unlogged relation (table/index) files from backup. Implemented using the same logic as the patches adding this feature to <postgres/>, <link url="https://git.postgresql.org/pg/commitdiff/8694cc96b52a967a49725f32be7aa77fd3b6ac25">8694cc96</link> and <link url="https://git.postgresql.org/pg/commitdiff/920a5e500a119b03356fb1fb64a677eb1aa5fc6f">920a5e50</link>.

<p>Allow arbitrary directories and/or files to be excluded from a backup. Misuse of this feature can lead to inconsistent backups so read the <br-option>--exclude</br-option> documentation carefully before using.</p>
</release-item>
<release-item>
<p>Add <br-option>log-subprocess</br-option> option to allow file logging for <id>local</id> and <id>remote</id> subprocesses.</p>

<p>Abstract IO layer out of the storage layer. This allows the routines to be used for IO objects that do not have a storage representation. Implement buffer read and write IO objects. Implement filters and update <code>cryptoHash</code> to use the new interface. Implement size and buffer filters.</p>
</release-item>
<release-item>
<p><code>storageFileRead()</code> accepts a buffer for output rather than creating one. This is more efficient overall and allows the caller to specify how many bytes will be read on each call. Reads are appended if the buffer already contains data but the buffer size will never increase.</p>

<p>Do nothing in <code>memContextMove()</code> when the context is already in the specified parent.</p>
