晋太元中，武陵人捕鱼为业。缘溪行，忘路之远近。忽逢桃花林，夹岸数百步，中无杂树，芳草鲜美，落英缤纷。渔人甚异之，复前行，欲穷其林。 　　林尽水源，便得一山，山有小口，仿佛若有光。便舍船，从口入。初极狭，才通人。复行数十步，豁然开朗。土地平旷，屋舍俨然，有良田、美池、桑竹之属。阡陌交通，鸡犬相闻。其中往来种作，男女衣着，悉如外人。黄发垂髫，并怡然自乐。 　　见渔人，乃大惊，问所从来。具答之。便要还家，设酒杀鸡作食。村中闻有此人，咸来问讯。自云先世避秦时乱，率妻子邑人来此绝境，不复出焉，遂与外人间隔。问今是何世，乃不知有汉，无论魏晋。此人一一为具言所闻，皆叹惋。余人各复延至其家，皆出酒食。停数日，辞去。此中人语云：“不足为外人道也。”(间隔 一作：隔绝) 　　既出，得其船，便扶向路，处处志之。及郡下，诣太守，说如此。太守即遣人随其往，寻向所志，遂迷，不复得路。 　　南阳刘子骥，高尚士也，闻之，欣然规往。未果，寻病终。后遂无问津者。 .

			<section title="Upgrading to `1.*`">
				<text><![CDATA[
The new `1.*` release **does not break compatibility** with `0.*` and nothing need to change to upgrade. However, the global `parse_user_agent` is now deprecated; it has been replaced with the namespaced `\donatj\UserAgent\parse_user_agent` and functions exactly the same. You can easily replace any existing call to `parse_user_agent` with `\donatj\UserAgent\parse_user_agent`

In addition, 1.x adds a convenience object wrapper you may use should you prefer. More information on this is in the Usage section below.

			<section title="Why Use This">
				<text><![CDATA[
You have your choice in user-agent parsers. This one detects **all modern browsers** in a very light, quick, understandable fashion.
It is less than 200 lines of code, and consists of just three regular expressions!
It can also correctly identify exotic versions of IE others fail on.

It offers 100% unit test coverage, is installable via Composer, and is very easy to use.

			</section>
			<section title="What It Does Not Do">
				<text><![CDATA[
This is not meant as a browser "knowledge engine" but rather a simple parser. Anything not adequately provided directly by the user agent string itself will simply not be provided by this.
]]></text>

				<section title="OS Versions">
					<text><![CDATA[
User-agent strings **are not** a reliable source of OS Version!

- Many agents simply don't send the information.
- Others provide varying levels of accuracy.
- Parsing Windows versions alone almost nearly doubles the size of the code.

I'm much more interested in keeping this thing *tiny* and accurate than adding niché features and would rather focus on things that can be **done well**.

All that said, there is the start of a [branch to do it](https://github.com/donatj/PhpUserAgent/tree/os_version_detection) I created for a client if you want to poke it, I update it from time to time, but frankly if you need to *reliably detect OS Version*, using user-agent isn't the way to do it. I'd go with JavaScript.

				<section title="Undetectable Browsers">
					<text><![CDATA[
- **Brave** - Brave is simply not differentiable from Chrome. This was a design decision on their part.
]]></text>
				</section>
				<section title="Undetectable Platforms">
					<text><![CDATA[
- **iPadOS 13+** - Starting with iPadOS 13 and further hardened in 14, iPadOS returns the **exact** same string as macOS. It is no longer distinguishable by UA string. (See: [#69](https://github.com/donatj/PhpUserAgent/issues/69))
