-## What's new in version 0.2
+## News [2023-01-27]
+Since December 2022 Yahoo has been encrypting the web data that `yfinance` scrapes for non-market data. Fortunately the decryption keys are available, although Yahoo moved/changed them several times hence `yfinance` breaking several times. `yfinance` is now better prepared for any future changes by Yahoo.

- Optimised web scraping
- All 3 financials tables now match website so expect keys to change. If you really want old tables, use [`Ticker.get_[income_stmt|balance_sheet|cashflow](legacy=True, ...)`](https://github.com/ranaroussi/yfinance/blob/85783da515761a145411d742c2a8a3c1517264b0/yfinance/base.py#L968)
- price data improvements: fix bug NaN rows with dividend; new repair feature for missing or 100x prices `download(repair=True)`; new attribute `Ticker.history_metadata`
-[See release notes for full list of changes](https://github.com/ranaroussi/yfinance/releases/tag/0.2.1)
+Why is Yahoo doing this? We don't know. Is it to stop scrapers? Maybe, so we've implemented changes to reduce load on Yahoo. In December we rolled out version 0.2 with optimised scraping. ~Then in 0.2.6 introduced `Ticker.fast_info`, providing much faster access to some `info` elements wherever possible e.g. price stats and forcing users to switch (sorry but we think necessary). `info` will continue to exist for as long as there are elements without a fast alternative.~ `info` now fixed and much faster than before.

-### Timezone cache store
+Review the [Wiki](https://github.com/ranaroussi/yfinance/wiki) for more options and detail.
+
+### Logging
+
+`yfinance` now uses the `logging` module. To control the detail of printed messages you simply change the level:
+```
+import logging
+logger = logging.getLogger('yfinance')
+logger.setLevel(logging.ERROR)  # default: only print errors
+logger.setLevel(logging.CRITICAL)  # disable printing
+logger.setLevel(logging.DEBUG)  # verbose: print errors & debug info
+```
+
+### Smarter scraping
+
+To use a custom `requests` session (for example to cache calls to the
+API or customize the `User-agent` header), pass a `session=` argument to
+the Ticker constructor.

-When fetching price data, all dates are localized to stock exchange timezone. 
-But timezone retrieval is relatively slow, so yfinance attemps to cache them 
-in your users cache folder. 
-You can direct cache to use a different location with `set_tz_cache_location()`:
 ```python
-import yfinance as yf
-yf.set_tz_cache_location("custom/cache/location")
-...
+import requests_cache
+session = requests_cache.CachedSession('yfinance.cache')
+session.headers['User-agent'] = 'my-program/1.0'
+ticker = yf.Ticker('msft', session=session)
+# The scraped response will be stored in the cache
+ticker.actions
+```
+
+Combine a `requests_cache` with rate-limiting to avoid triggering Yahoo's rate-limiter/blocker that can corrupt data.
+```python
+from requests import Session
+from requests_cache import CacheMixin, SQLiteCache
+from requests_ratelimiter import LimiterMixin, MemoryQueueBucket
+from pyrate_limiter import Duration, RequestRate, Limiter
+class CachedLimiterSession(CacheMixin, LimiterMixin, Session):
+    pass
+
+session = CachedLimiterSession(
+    limiter=Limiter(RequestRate(2, Duration.SECOND*5),  # max 2 requests per 5 seconds
+    bucket_class=MemoryQueueBucket,
+    backend=SQLiteCache("yfinance.cache"),
+)
